Re: any solution about array_walk with pass-by-reference UseData?

Online document say's Note: Please note that this function only checks one dimension of a n-dimensional array. Of course you can check deeper dimensions by using, for example, array_udiff_uassoc($array1[0], $array2[0], "data_compare_func", "key_compare_func");. It's not my needed My need is $disable_full=array("a","b","c"); $disable_start=array("_","HTTP"); $check_array=array(array("http"=>"a"),"a"=>"dabdd"); I want to unset all element's key full match in $disable_full and start with string in $disable_start array; 2010/1/13 Joey Smith <joey@joeysmith.com>: > This might be better served by taking it to php-general, because I don't > think you need to pin your question so hard to the behaviour of > array_walk().
