Not reproducible. Btw, this code - $rep = '\$2\$1'; apparently won't work. Previous Comments: ------------------------------------------------------------------------ [2006-11-30 16:55:02] ivo_gelov at abv dot bg Description: ------------ There are 2 strange effects/bugs, may be one depends on the other, I do not know. 1. PREG_REPLACE does not recognize $n as a back reference in its second argument. It will recognize only \\n references. 2. PREG_REPLACE returns NULL if no match is found, instead of returning unmodified subject This symptom is present only in 5.2.0 - there are no problems with 5.1.0 Reproduce code: --------------- $pat = '/^([a-zA-Z])(\d*)$/'; $rep = '\$2\$1'; $b = preg_replace($pat,$rep,'D764209812'); Expected result: ---------------- $b should be '764209812D' Actual result: -------------- $b is NULL ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=39695&edit=1
