按指定元素值去除数组元素
代码如下:
<?php //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 )
