phpWe often need to operate on arrays. Sometimes we may need to add units into the array,phpThe array_push() function is built into it, which can push one or more units to the end of the array (on the stack). This article will take you to take a look at it, and first understand the syntax.

array_push   ( array $array   , mixed $value1  , mixed $... = ?  )

• $array: Input array.

• $value1,...: To push the end value of array.

• Return value: Returns the number of elements in the array after processing.

<?php
$arr=array("a"=>"A张三","c"=>"b李四","b"=>"a王五");
$num=array_push($arr,"陆六","金七");
echo $num,"<br>";
print_r($arr);
?>
