PREG_FILTER(3)								 1							    PREG_FILTER(3)

preg_filter - Perform a regular expression search and replace

SYNOPSIS
mixed preg_filter (mixed $pattern, mixed $replacement, mixed $subject, [int $limit = -1], [int &$count]) DESCRIPTION
preg_filter(3) is identical to preg_replace(3) except it only returns the (possibly transformed) subjects where there was a match. For details about how this function works, read the preg_replace(3) documentation. RETURN VALUES
Returns an array if the $subject parameter is an array, or a string otherwise. If no matches are found or an error occurred, an empty array is returned when $subject is an array or NULL otherwise. EXAMPLES
Example #1 Example comparing preg_filter(3) with preg_replace(3) <?php $subject = array('1', 'a', '2', 'b', '3', 'A', 'B', '4'); $pattern = array('/d/', '/[a-z]/', '/[1a]/'); $replace = array('A:$0', 'B:$0', 'C:$0'); echo "preg_filter returns "; print_r(preg_filter($pattern, $replace, $subject)); echo "preg_replace returns "; print_r(preg_replace($pattern, $replace, $subject)); ?> The above example will output: preg_filter returns Array ( [0] => A:C:1 [1] => B:C:a [2] => A:2 [3] => B:b [4] => A:3 [7] => A:4 ) preg_replace returns Array ( [0] => A:C:1 [1] => B:C:a [2] => A:2 [3] => B:b [4] => A:3 [5] => A [6] => B [7] => A:4 ) SEE ALSO
