                                   preg_grep

   (PHP 4 )
   preg_grep --  Return array entries that match the pattern

Description

   array preg_grep ( string pattern, array input)

   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.

   Example 1. preg_grep() example
   <?php
   // return all array elements
   // containing floating point numbers
   $fl_array = preg_grep("/^(\d+)?\.\d+$/", $array);
   ?>
