Here's one way to do it in PHP. There are possibly better ways.
#!/usr/bin/php -q <?php error_reporting(E_ALL); $data = array("one", "foo", "two", "foo", "three", "foo", "four", "foo", "foo"); $changed = 0; $new = preg_replace_callback("/foo/", create_function( '', '$GLOBALS{"changed"}++; return "bar";' ), $data); print_r($new); print "We changed $changed items\n"; ?>
This prints
Array ( [0] => one [1] => bar [2] => two [3] => bar [4] => three [5] => bar [6] => four [7] => bar [8] => bar ) We changed 5 items
I hope this helps satisfy your curiosity
