array_push — 배열의 끝에 하나 이상의 원소를 넣는다
설명 ¶
array_push()는 array를 스택으로 취급하고, array 끝에 전달되어진 변수를 넣는다. array의 길이는 집어넣은 변수의 수만큼 증가한다. 다음과 같은 효과를 갖는다:
<?php
$array[] = $var;
?>var에 대해 반복된다.인수 ¶
array입력 배열.
var넣을 값.
반환값 ¶
배열에 새로 추가된 원소의 수를 반환한다.
예제 ¶
Example #1 array_push() 예제
<?php
$stack = array("orange", "banana");
array_push($stack, "apple", "raspberry");
print_r($stack);
?>위 예제의 출력:
Array
(
[0] => orange
[1] => banana
[2] => apple
[3] => raspberry
)
참고 ¶
- array_pop() - 배열의 마지막 원소 빼내기
- array_push()
- array_unshift() - 배열의 맨 앞에 하나 이상의 원소를 첨가

If you're going to use array_push() to insert a "$key" => "$value" pair into an array, it can be done using the following:
$data[$key] = $value;
It is not necessary to use array_push.408

I've done a small comparison between array_push() and the $array[] method and the $array[] seems to be a lot faster.
<?php
$array = array();
for ($x = 1; $x <= 100000; $x++)
{
$array[] = $x;
}
?>
takes 0.0622200965881 seconds
and
<?php
$array = array();
for ($x = 1; $x <= 100000; $x++)
{
array_push($array, $x);
}
?>
takes 1.63195490837 seconds
so if your not making use of the return value of array_push() its better to use the $array[] way.
Hope this helps someone.8

Need a real one-liner for adding an element onto a new array name?
$emp_list_bic = $emp_list + array(c=>"ANY CLIENT");
CONTEXT...
drewdeal: this turns out to be better and easier than array_push()
patelbhadresh: great!... so u discover new idea...
drewdeal: because you can't do: $emp_list_bic = array_push($emp_list, c=>"ANY CLIENT");
drewdeal: array_push returns a count and affects current array.. and does not support set keys!
drewdeal: yeah. My one-liner makes a new array as a derivative of the prior array9

Skylifter notes on 20-Jan-2004 that the [] empty bracket notation does not return the array count as array_push does. There's another difference between array_push and the recommended empty bracket notation.
Empy bracket doesn't check if a variable is an array first as array_push does. If array_push finds that a variable isn't an array it prints a Warning message if E_ALL error reporting is on.
So array_push is safer than [], until further this is changed by the PHP developers.3

Rodrigo de Aquino asserted that instead of using array_push to append to an associative array you can instead just do...
$data[$key] = $value;
...but this is actually not true. Unlike array_push and even...
$data[] = $value;
...Rodrigo's suggestion is NOT guaranteed to append the new element to the END of the array. For instance...
$data['one'] = 1;
$data['two'] = 2;
$data['three'] = 3;
$data['four'] = 4;
...might very well result in an array that looks like this...
[ "four" => 4, "one" => 1, "three" => 3, "two" => 2 ]
I can only assume that PHP sorts the array as elements are added to make it easier for it to find a specified element by its key later. In many cases it won't matter if the array is not stored internally in the same order you added the elements, but if, for instance, you execute a foreach on the array later, the elements may not be processed in the order you need them to be.
If you want to add elements to the END of an associative array you should use the unary array union operator (+=) instead...
$data['one'] = 1;
$data += [ "two" => 2 ];
$data += [ "three" => 3 ];
$data += [ "four" => 4 ];
You can also, of course, append more than one element at once...
$data['one'] = 1;
$data += [ "two" => 2, "three" => 3 ];
$data += [ "four" => 4 ];
Note that like array_push (but unlike $array[] =) the array must exist before the unary union, which means that if you are building an array in a loop you need to declare an empty array first...
$data = [];
for ( $i = 1; $i < 5; $i++ ) {
$data += [ "element$i" => $i ];
}
...which will result in an array that looks like this...
[ "element1" => 1, "element2" => 2, "element3" => 3, "element4" => 4 ]35

If you're adding multiple values to an array in a loop, it's faster to use array_push than repeated [] = statements that I see all the time:
<?php
class timer
{
private $start;
private $end;
public function timer()
{
$this->start = microtime(true);
}
public function Finish()
{
$this->end = microtime(true);
}
private function GetStart()
{
if (isset($this->start))
return $this->start;
else
return false;
}
private function GetEnd()
{
if (isset($this->end))
return $this->end;
else
return false;
}
public function GetDiff()
{
return $this->GetEnd() - $this->GetStart();
}
public function Reset()
{
$this->start = microtime(true);
}
}
echo "Adding 100k elements to array with []\n\n";
$ta = array();
$test = new Timer();
for ($i = 0; $i < 100000; $i++)
{
$ta[] = $i;
}
$test->Finish();
echo $test->GetDiff();
echo "\n\nAdding 100k elements to array with array_push\n\n";
$test->Reset();
for ($i = 0; $i < 100000; $i++)
{
array_push($ta,$i);
}
$test->Finish();
echo $test->GetDiff();
echo "\n\nAdding 100k elements to array with [] 10 per iteration\n\n";
$test->Reset();
for ($i = 0; $i < 10000; $i++)
{
$ta[] = $i;
$ta[] = $i;
$ta[] = $i;
$ta[] = $i;
$ta[] = $i;
$ta[] = $i;
$ta[] = $i;
$ta[] = $i;
$ta[] = $i;
$ta[] = $i;
}
$test->Finish();
echo $test->GetDiff();
echo "\n\nAdding 100k elements to array with array_push 10 per iteration\n\n";

array_push($ta,$i,$i,$i,$i,$i,$i,$i,$i,$i,$i);

If you push an array onto the stack, PHP will add the whole array to the next element instead of adding the keys and values to the array. If this is not what you want, you're better off using array_merge() or traverse the array you're pushing on and add each element with $stack[$key] = $value.
<?php
$stack = array('a', 'b', 'c');
array_push($stack, array('d', 'e', 'f'));
print_r($stack);
?>
The above will output this:
Array (
[0] => a
[1] => b
[2] => c
[3] => Array (
[0] => a
[1] => b
[2] => c
)

Looking for a way to push data into an associative array and frustrated to know that array_push() can't do the job ?
here's my Scenario :
-------------------
I need to relate system command output into an associative array like these :
[sge@digital_db work]$ /usr/local/apache/htdocs/work/qhost.sh -h t1 -F | awk '{if(NR>4) print $1}' | sed 's/hl://g'
arch=lx24-amd64
num_proc=2.000000
mem_total=3.808G
swap_total=3.907G
virtual_total=7.715G
load_avg=0.000000
load_short=0.000000
load_medium=0.000000
load_long=0.000000
mem_free=3.510G
swap_free=3.907G
virtual_free=7.417G
mem_used=305.242M
swap_used=0.000
virtual_used=305.242M
cpu=0.000000
np_load_avg=0.000000
np_load_short=0.000000
np_load_medium=0.000000
np_load_long=0.000000
how I did it :
<? php
# get into the system command output
$assoc_cmd =`$work_dir/qhost.sh -h $host_resource -F | awk '{if(NR>4) print $1}'| sed 's/hl://g' ` ;
# split the "\n" character
$assoc_row = explode("\n", chop($assoc_cmd));
# get the index row
$idx_row = count($assoc_row) - 1 ;
# initialize the associative array
$host_res_array = array();
for ($i = 0 ; $i<= $idx_row ; $i++)
{
# get params & values
list($host_param,$host_val) = explode("=",$assoc_row[$i]);
# populate / push data to assoc array
$host_res_array[$host_param]= $host_val ;
}
echo "<pre> Architecture : </pre>\n" ;
echo $host_res_array['arch'] ;
echo "<pre> Mem Total : </pre>\n" ;
echo $host_res_array['mem_tot'];
?>
Hope this helps ! :)4

If you want to preserve the keys in the array, use the following:
<?php
function array_pshift(&$array) {
$keys = array_keys($array);
$key = array_shift($keys);
$element = $array[$key];
unset($array[$key]);
return $element;
}

If the element to be pushed onto the end of array is an array you will receive the following error message:
Unknown Error, value: [8] Array to string conversion
I tried both: (and works, but with the warning message)
$aRol = array( $row[0], $row[1], $row[2] );
$aRoles[] = $aRol;
and
array_push( $aRoles, $aRol);
The correct way:
$cUnRol = implode("(",array( $row[0], $row[1], $row[2] ) );
array_push( $aRoles, $cUnRol );

When developing a pocketmine plugin, a good way to add stuff to a YAML table is
$table=$this->config->get("Table");
array_push($table, "New Value for table");
$this->config->set("Table", $table);-1

Unfortunately array_push returns the new number of items in the array
It does not give you the key of the item you just added, in numeric arrays you could do -1, you do however need to be sure that no associative key exists as that would break the assumption
It would have been better if array_push would have returned the key of the item just added like the below function
(perhaps a native variant would be a good idea...)
<?php
if(!function_exists('array_add')){
function array_add(array &$array,$value /*[, $...]*/){
$values = func_get_args(); //get all values
$values[0]= &$array; //REFERENCE!
$org=key($array); //where are we?
call_user_func_array('array_push',$values);
end($array); // move to the last item
$key = key($array); //get the key of the last item
if($org===null){
//was at eof, added something, move to it
return $key;
}elseif($org<(count($array)/2)){ //somewhere in the middle +/- is fine
reset($array);
while (key($array) !== $org) next($List);
}else{
while (key($array) !== $org) prev($List);
}
return $key;
}
}
echo "<pre>\n";
$pr = array('foo'=>'bar','bar'=>'foo');
echo "Taken array;";
print_r($pr);
echo "\npush 1 returns ".array_push($pr,1)."\n";
echo "------------------------------------\n";
$pr = array('foo'=>'bar','bar'=>'foo');
echo "\npush 2 returns ".array_push($pr,1,2)."\n";
echo "------------------------------------\n";
$pr = array('foo'=>'bar','bar'=>'foo');
echo "\n add 1 returns ".array_add($pr,2)."\n\n";
echo "------------------------------------\n";
$pr = array('foo'=>'bar','bar'=>'foo');
echo "\n add 2 returns ".array_add($pr,1,2)."\n\n";
echo "<pre/>\n\n";
?>
Outputs:
Taken array;Array
(
[foo] => bar
[bar] => foo
)
push 1 returns 3
------------------------------------
push 2 returns 4

add 1 returns 0

I did a performance check, and I saw, if you push more than one value it can be faster the array push, that the normal $array[] version.
Case 1: $array[] = something;
Case 2: array_push($array, $value);
Case 3: array_push($array, $value1, $value2, $value3 [...]); $values are definied
Case 4: array_push($array, $value1, $value2, $value3 [...]); $values are definied, when $array is not empty
Case 5: Case1 + Case 3
Case 6: Result array contains some value (Case 4)
Case 7: Result array contains same value as the push array (Case 4)

Be warned using $array "+=" array(1,2,3) or union operations (http://php.net/manual/en/language.operators.array.php)
I think it worked in the past or i havent test it good enough. :-/
(once it worked, once [] was faster than array_push, the past :-D ):
php -r '$a = array(1,2); $a += array(3,4); print_r($a);'
Array (
[0] => 1
[1] => 2
)
php -r '$a = array(1,2); $b = array(3,4);$c = $a + $b; print_r($c);'

I found a simple way to have an "array_push_array" function, without the references problem when we want to use call_user_func_array(), hope this help :
function array_push_array(array &$array)
{
$numArgs = func_num_args();
if(2 > $numArgs)
{
trigger_error(sprintf('%s: expects at least 2 parameters, %s given', __FUNCTION__, $numArgs), E_USER_WARNING);
return false;
}
$values = func_get_args();
array_shift($values);
foreach($values as $v)
{
if(is_array($v))
{
if(count($v) > 0)
{
foreach($v as $w)
{
$array[] = $w;
}
}
}
else
{
$array[] = $v;
}
}
return count($array);

A function which mimics push() from perl, perl lets you push an array to an array: push(@array, @array2, @array3). This function mimics that behaviour.
<?php
function array_push_array(&$arr) {
$args = func_get_args();
array_shift($args);
if (!is_array($arr)) {
trigger_error(sprintf("%s: Cannot perform push on something that isn't an array!", __FUNCTION__), E_USER_WARNING);
return false;
}
foreach($args as $v) {
if (is_array($v)) {
if (count($v) > 0) {
array_unshift($v, &$arr);
call_user_func_array('array_push', $v);
}
} else {
$arr[] = $v;
}
}
return count($arr);
}
$arr = array(0);
$arr2 = array(6,7,8);
printf("%s\n", array_push_array($arr, array(),array(1,2,3,4,5), $arr2));
print_r($arr);
# error..
$arr = "test";
printf("%s\n", array_push_array($arr, array(),array(1,2,3,4,5), $arr2));

This will work to solve the associative array issues:
$aValues[$key] = $value;
Where $key is a unique identifier and $value is the value to be stored. Since the $key works off a string or number, if you already have a $key with the same value as an existing $key, the element will be overwritten.
e.g.
$aValues["one"] = "value of one";
$aValues["two"] = "different value of two!";
gives:
array([one] => "value of one", [two] => "value of two");
but will be overwritten when using the same key (one):
$aValues["one"] = "value of one";
$aValues["one"] = "different value of two!";
will give:
array([one] => "different value of two!");

A very good function to remove a element from array
function array_del($str,&$array)
{
if (in_array($str,$array)==true)
{
foreach ($array as $key=>$value)
{
if ($value==$str) unset($array[$key]);
}
}

A small and basic implementation of a stack without using an array.
class node
{
var $elem;
var $next;
}
class stack
{
var $next;
function pop()
{
$aux=$this->next->elem;
$this->next=$this->next->next;
return $aux;
}
function push($obj)
{
$nod=new node;
$nod->elem=$obj;
$nod->next=$this->next;
$this->next=$nod;
}
function stack()
{
$this->next=NULL;
}
}0

Further Modification on the array_push_associative function
1. removes seemingly useless array_unshift function that generates php warning
2. adds support for non-array arguments
<?
// Append associative array elements
function array_push_associative(&$arr) {
$args = func_get_args();
foreach ($args as $arg) {
if (is_array($arg)) {
foreach ($arg as $key => $value) {
$arr[$key] = $value;
$ret++;
}
}else{
$arr[$arg] = "";
}
}
return $ret;
}
$items = array("here" => "now");
$moreitems = array("this" => "that");
$theArray = array("where" => "do we go", "here" => "we are today");
echo array_push_associative($theArray, $items, $moreitems, "five") . ' is the size of $theArray.<br />';
echo "<pre>";
print_r($theArray);
echo "</pre>";
?>
Yields:
4 is the size of $theArray.
Array
(
[where] => do we go
[here] => now
[this] => that
[five] =>
)0

A variation of kamprettos' associative array push:
// append associative array elements
function associative_push($arr, $tmp) {
if (is_array($tmp)) {
foreach ($tmp as $key => $value) {
$arr[$key] = $value;
}
return $arr;
}
return false;
}
$theArray = array();
$theArray = associative_push($theArray, $items);0

regarding the speed of oneill's solution to insert a value into a non-associative array, I've done some tests and I found that it behaves well if you have a small array and more insertions, but for a huge array and a little insersions I sugest using this function:
function array_insert( &$array, $index, $value ) {
$cnt = count($array);
for( $i = $cnt-1; $i >= $index; --$i ) {
$array[ $i + 1 ] = $array[ $i ];
}
$array[$index] = $value;
}
or if you are a speed adicted programmer (same situation: big array, few insertions) use this:
array_splice ( $array, $offset, 0, $item );
item may also be an array of values ;).0

As someone pointed out the array_push() function returns the count of the array not the key of the new element. As it was the latter function i required i wrote this very simple replacement.
function array_push2(&$array,$object,$key=null){
$keys = array_keys($array);
rsort($keys);
$newkey = ($key==null)?$keys[0]+1:$key;
$array[$newkey] = $object;
return $newkey;
}0

Array_push also works fine with multidimensional arrays. Just make sure the element is defined as an array first.
<?php
$array["element"][$element]["element"] = array();
array_push ($array["element"][$element]["element"], "banana");

If you want to put an element to a specific position in an array, try this function.
<?php
function array_put_to_position(&$array, $object, $position, $name = null)
{
$count = 0;
$return = array();
foreach ($array as $k => $v)
{
// insert new object
if ($count == $position)
{
if (!$name) $name = $count;
$return[$name] = $object;
$inserted = true;
}
// insert old object
$return[$k] = $v;
$count++;
}
if (!$name) $name = $count;
if (!$inserted) $return[$name];
$array = $return;
return $array;
}
?>
Example :
<?php
$a = array(
'a' => 'A',
'b' => 'B',
'c' => 'C',
);
print_r($a);
array_put_to_position($a, 'G', 2, 'g');
print_r($a);
/*
Array
(
[a] => A
[b] => B
[c] => C
)
Array
(
[a] => A
[b] => B
[g] => G
[c] => C
)
*/

To insert a value into a non-associative array, I find this simple function does the trick:
function insert_in_array_pos($array, $pos, $value)
{
$result = array_merge(array_slice($array, 0 , $pos), array($value), array_slice($array, $pos));
return $result;
}
Seems an awful lot simpler than the iterative solutions given above...'WEB > jQuery' 카테고리의 다른 글
