Here,

這里，

• array is the source array in which we have to push the elements.

  array是我們必須在其中推送元素的源數組。

  element是要添加的值，我們也可以添加多個元素。

Examples:

例子：

    Input:
//initial array is
$arr = array(100, 200, 300);
//pushing elements
array_push($arr, 10);
array_push($arr, 400, 500);
Output:
Array
(    
[0] => 100
[1] => 200
[2] => 300
[3] => 10 
[4] => 400
[5] => 500
)

PHP code 1: Inserting elements in an indexed array

PHP代碼1：在索引數組中插入元素

<?php
$arr = array(100, 200, 300);
array_push($arr, 10);
array_push($arr, 400, 500);
print("array after inserting elements...\n");
print_r($arr);
?>

Output

輸出量

random key: age
array of random keys...
Array          
(              
[0] => age 
[1] => city
)

PHP code 2: Inserting elements in an associative array

PHP代碼2：在關聯數組中插入元素

<?php
$arr = array("name" => "Amit", "age" => 21);
array_push($arr, "Gwalior");
array_push($arr, "Male", "RGTU University");
print("array after inserting elements...\n");
print_r($arr);
?>

Output

輸出量

array after inserting elements...
Array             
(  
[name] => Amit
[age] => 21
[0] => Gwalior
[1] => Male
[2] => RGTU University
) 

See the output – There are two keys name and age and we added three more elements "Gwalior", "Male" and "RGTU University", these three elements added with the keys 0, 1 and 2.

看到輸出-有兩個關鍵的姓名和年齡 ，我們增加了三個要素“瓜廖爾”，“ 男性”和“RGTU大學”，與鍵0，1和2添加了這三個要素。
