#24375 [Bgs]: php.exe - Application error caused when I execute preg_replace

ID: 24375 User updated by: zvorygin at kenjitsu dot net Reported By: zvorygin at kenjitsu dot net Status: Bogus Bug Type: PCRE related Operating System: Win2000 PHP Version: 4.3.1 New Comment: Hello, It's me, zvorygin again. Downloading of new version is in process. I have reread documentation few times again and found: ------------- Every parameter to preg_replace() (except limit) can be an array. If subject is an array, then the search and replace is performed on every entry of subject, and the return value is an array as well. If pattern and replacement are arrays, then preg_replace() takes a value from each array and uses them to do search and replace on subject. If replacement has fewer values than pattern, then empty string is used for the rest of replacement values. If pattern is an array and replacement is a string, then this replacement string is used for every value of pattern. The converse would not make sense, though. /e modifier makes preg_replace() treat the replacement parameter as PHP code after the appropriate references substitution is done. Tip: make sure that replacement constitutes a valid PHP code string, otherwise PHP will complain about a parse error at the line containing preg_replace(). ------------------------- So we don't see what will happen if pattern is string and replacement is array! Maybe, Developers has just forgot to take a look at this case? because when I replace: ------------- return preg_replace("/<!--#(.*)-->/U",$repl,$text); ------------- with ------------ $pattern=array("/<!--&(.*)-->/U"); return preg_replace($pattern,$repl,$text); ------------ Everything works nice!
