php数组函数array_push()、array_pop()及array_shift()简单用法示例
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
- )
