array_filter 过滤一维中空数组,数组的序列不变
<?php header('Content-type:text;charset=utf8'); $str = "%11111%22222%333333%"; $arr = explode('%',$str); print_r($arr); print_r(array_filter($arr)); ?>
--------------------------------------------------
Array ( [0] => [1] => 11111 [2] => 22222 [3] => 333333 [4] => ) Array ( [1] => 11111 [2] => 22222 [3] => 333333 )
