preg_grep
(PHP 4)
Description
preg_grep() returns the array consisting of the elements of the input array that match the given pattern.
Since PHP 4.0.4, the results returned by preg_grep() are indexed using the keys from the input array. If this behavior is undesirable, use array_values() on the array returned by preg_grep() to reindex the values.
瞰赽 1. preg_grep() example
// return all array elements // containing floating point numbers $fl_array = preg_grep ("/^(\d+)?\.\d+$/", $array);
