Bug #10668: preg_replace backquote failure

From: smoonen@andstuff.org Operating system: Linux PHP version: 4.0.5 PHP Bug Type: PCRE related Bug description: preg_replace backquote failure The following code succeeds on PHP 4.03 and PHP 4.04pl1, but fails on PHP 4.05: $str = "abc'\\\\''def"; function f($s) { return "x"; } print preg_replace("/c(.*)d/e", "f('\\1')", $str, -1); This seems to expose *two* underlying bugs: 1) There appears to be some problem in the regex state machine 2) There is a definite problem with the replacement of the backreference with its corresponding string. -- Edit Bug report at: http://bugs.php.net/?id=10668&edit=1
