删除数组中一个元素我们是最常见的了，今天只简单的介绍一下关于删除最后一个元素哦，如果想删除数组中的任意一个，可以利用我第二种方法，再加个if(){ unset()}就可以实现了。

实例

 代码如下 复制代码

$stack = array("orange", "banana", "apple", "raspberry");
$fruit = array_pop($stack);
print_r($stack);
?>
经过此操作后，$stack 将只有 3 个单元：

Array
(
    [0] => orange
    [1] => banana
    [2] => apple
)


array_pop() 弹出并返回 array 数组的最后一个单元，并将数组 array 的长度减一。如果 array 为空（或者不是数组）将返回 NULL


用了函数我们还可以利用其它的方法如

 代码如下 复制代码


$array = array('ccc','www.hzhuti.com','abc','bKjia.c0m');
$arrtmp = array();
for( $i=0;$i {
 $arrtmp[] = $array[$i];
}
print_r($arrtmp);

Array
(
    [0] => ccc
    [1] => www.hzhuti.com
    [2] => abc
)

?>
