This article analyzes common functions for adding and deleting units in PHP arrays through examples. Share it with everyone for your reference. The specific analysis is as follows:

<&#63;php
header("Content-type:text/html;charset=utf-8");
$arr = array("a"=>"Horse","b"=>"Cat","c"=>"Dog");
array_push($arr,"hello","world");
//array_push将一个或多个单元压入到数组末尾
print_r($arr);
echo "<br />";

//array_pop()：删除数组的最后一个单元
array_pop($arr);
print_r($arr);
echo "<br />";

//array_shift()：删除数组的第一个单元
array_shift($arr);
print_r($arr);
echo "<br />";

//array_unshift()：在数组开头添加一个或多个单元
array_unshift($arr,"Horse");
print_r($arr);
