It took me a while to figure this one out, but here is a nice way to use preg_replace to convert a
hex encoded string back to clear text
<?php
$text = "PHP rocks!";
$encoded = preg_replace(
"'(.)'e"
,"dechex(ord('\\1'))"
,$text
);
print "ENCODED: $encoded\n";
?>
ENCODED: 50485020726f636b7321
<?php
print "DECODED: ".preg_replace(
"'([\S,\d]{2})'e"
,"chr(hexdec('\\1'))"
,$encoded)."\n";
?>
DECODED: PHP rocks!
