php数组过滤

1. //fast filtering values of a array
2. function fast_array_filter($array,$partten){
3. $partten = '/' . preg_quote($partten) .'/';
4. return preg_grep ($partten, $array);
5. }
6. //fast filtering keys of a array
7. function fast_array_keys_filter($array,$partten){
8. $partten = '/' . preg_quote($partten) .'/';
9. $keys = preg_grep($partten,array_keys($array));
10. //$retArray = array_combine ($keys , array_fill(0,count($keys),0) );
11. $retArray = array_flip($keys)
12. return array_intersect_key($array,$retArray);
13. }

 

 

如过需要过滤除 空值 null 0 false 意外的任何值 fast_array_filter（$array ,'/[^0]/'）;
