数组元素删除有很多种情况,一种是删除第一个元素或随意一个元素或删除数组中空元素,下面我总结一下删除数组元素的一些实例
实例一

实例二
array_flip() 删除数组重复元素
如:
代码如下 | 复制代码 |
$arr1 = array (”age” => 30, “name” => “快乐园”, “age” => 20); 上面的代码写得简洁一些就是: $arr1 = array_flip(array_flip($arr1)); |
实例三
array_pop 删除数组的最后一个元素
代码如下 | 复制代码 |
$user=array('apple','banana','orange'); |
删除数组中指定值的元素
一、利用foreach和unset()函数删除数组中的特定元素
代码如下 | 复制代码 |
foreach($array as $k=>$v){ |
unset()函数即删除指定的数组值。
二、利用array_flip()函数和unset()函数删除数组中的特定值
代码如下 | 复制代码 |
$arr = array_flip($arr); |
