原陣列:array

([0] => sdfdsdsdsfrrrrrrr

[1] => fdsfdsdsfds

[2] => fdsfdsdsfdsds

[3] => fdsdsfdsfds

[4] =>

[5] =>

[6] =>

[7] => fdsfdsfdsfds

[8] => fdsfdsfdsfdsfdsfsd

[9] => ssssssss

[10] =>

[11] => sssssssssssssssssssss

)處理之後陣列:array

([0] => sdfdsdsdsfrrrrrrr

[1] => fdsfdsdsfds

[2] => fdsfdsdsfdsds

[3] => fdsdsfdsfds

[4] => fdsfdsfdsfds

[5] => fdsfdsfdsfdsfdsfsd

[6] => ssssssss

[7] => sssssssssssssssssssss

)使用方法:$arr = array();

foreach ($urlarr as $key => $val)

$arr = $val;

}去除空元素方法一:(保持鍵值不變)

原陣列:

array(

[0] => sdfdsdsdsfrrrrrrr

[1] => fdsfdsdsfds

[2] => fdsfdsdsfdsds

[3] => fdsdsfdsfds

[4] =>

[5] =>

[6] =>

[7] => fdsfdsfdsfds

[8] => fdsfdsfdsfdsfdsfsd

[9] => ssssssss

[10] =>

[11] => sssssssssssssssssssss)

處理之後陣列array(

[0] => sdfdsdsdsfrrrrrrr

[1] => fdsfdsdsfds

[2] => fdsfdsdsfdsds

[3] => fdsdsfdsfds

[7] => fdsfdsfdsfds

[8] => fdsfdsfdsfdsfdsfsd

[9] => ssssssss

[11] => sssssssssssssssssssss)

使用方法:function myfunction($v)

return false;

}print_r(array_filter($urlarr, "myfunction"));
