本文实例讲述了php数组函数array_push()、array_pop()及array_shift()简单用法。分享给大家供大家参考，具体如下：
<?php
/**
* array_push()将一个或多个单元压入数组的末尾(入栈)
*/
$stack = array("Java", "Php", "C++");
array_push($stack, "C#", "Ruby", array('jsp', 'Asp'));
print_r($stack);
echo "====================================="."<br>";
/**
* array_pop() 将数组最后一个单元弹出（出栈）
*/
$stack = array("Java", "Php", "C++", "C#", "Ruby");
array_pop($stack);
print_r($stack);
echo "====================================="."<br>";
/**
* array_shift()将数组开头的单元移出数组 array_unshift()在数组开头插入一个或多个单元
*/
$stack = array("Java", "Php", "C++", "C#", "Ruby");
array_shift($stack);
print_r($stack);
?>
运行结果如下：
Array
(
[0] => Java
[1] => Php
[2] => C++
[3] => C#
[4] => Ruby
[5] => Array
(
[0] => jsp
[1] => Asp
))
=====================================
Array
(
[0] => Java
[1] => Php
[2] => C++
[3] => C#
)
=====================================
Array
(
[0] => Php
[1] => C++
[2] => C#
[3] => Ruby
)
