array_push

PHP array_push()函數(shù) (PHP array_push() function)

array_push() function is used to insert/push one or more than one element to the array.

array_push()函數(shù)用于將一個(gè)或多個(gè)元素插入/推入數(shù)組。

Syntax:

句法：

array_push(array, elemement1, [element2],..);

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(shù)組。

• element is the value to be added, we can add more than one elements too.

  element是要添加的值，我們也可以添加多個(gè)元素。

Examples:

例子：

Input://initial array is$arr = array(100, 200, 300);//pushing elementsarray_push($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(shù)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(guān)聯(lián)數(shù)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(gè)關(guān)鍵的姓名和年齡 ，我們?cè)黾恿巳齻€(gè)要素“瓜廖爾”，“ 男性”和“RGTU大學(xué)”，與鍵0，1和2添加了這三個(gè)要素。
