Which built-in function in php will add value at the end of array

The built-in function array_push() in php will add a value to the end of the array. The array_push() function can insert one or more elements (push) to the end of the array and return the array length after inserting the new elements. The syntax is "array_push(array,value1,value2...)".

PHP array_push() : Insert elements at the end of the array

array_push() function is used to insert one or more elements (push) at the end of the array. Its syntax is as follows:

array_push(array,value1,value2...)

Return value: Returns the length of the array after inserting the new element.

The array_push() function treats the original array array as a stack and pushes the incoming elements into the end of the array array; the length of the array will increase according to the number of elements pushed onto the stack.

Example 1:

<?php
header(&#39;content-type:text/html;charset=utf-8&#39;);   
$num = array(10, 45, 9);
echo "原数组：";
var_dump($num);
array_push($num, 100, 6);  //在数组结尾插入元素
echo "插入多个元素后：";
var_dump($num);
?>

Note: Even if your array has string keys, the elements you add will have numeric keys.

Example 2:

<?php
header(&#39;content-type:text/html;charset=utf-8&#39;);   
$arr= array("a"=>"red","b"=>"green");
echo "原数组：";
var_dump($arr);
array_push($arr, "blue","yellow");  //在数组结尾插入元素
echo "插入多个元素后：";
var_dump($arr);
?>
