按指定元素值去除数组元素

复制代码 代码如下:

//去除值为"Cat"的元素
$a=array("a"=>"Dog","b"=>"Cat","c"=>"Horse");
print_r($a);
unset($a[array_search("Cat",$a)]);//array_search("Cat",$a)按元素值返回键名。去除后保持索引
print_r($a);
?>

查看array_search用法

显示结果

去除前：
Array
(
[a] => Dog
[b] => Cat
[c] => Horse
)

去除后：

Array
(
[a] => Dog
[c] => Horse
)
