#39624 [NEW]: Regexp fails if there's more than 1 string to replace in the same line

From: nino at recgr dot com Operating system: Windows XP SP2(with all patches) PHP version: 5.2.0 PHP Bug Type: Regexps related Bug description: Regexp fails if there's more than 1 string to replace in the same line Description: ------------ A Regex command normally replaces (using preg_replace), but only when there is just one string to match in line. Otherwise it gives some unexpected(weird) code. I've tried some *similar* codes, and they are all buggy in the same way. Reproduce code: --------------- $s = preg_replace("#\[url\=(.*)\](.*)\[\/url\]#i", "<a href=\"$1\" target=\"_blank\">$2</a>", $s); Then, for instance, a $s would be: EXAMPLE #1 If you dunno, or have no idea, you can try looking up [url=http://www.here.com]here[/url]. EXAMPLE #2 If you dunno, or have no idea, you can try looking up [url=http://www.here.com]here[/url] or [url=http://www.anotherhere.com]here[/url] ! Expected result: ---------------- EXAMPLE #1 is fine, but I expect for EXAMPLE #2 to get this: If you dunno, or have no idea, you can try looking up <a href="http://www.here.com" target="_blank">here</a> or <a href="http://www.anotherhere.com">here</a> ! Actual result: -------------- EXAMPLE #1 works fine, I get this: If you dunno, or have no idea, you can try looking up <a href="http://www.here.com" target="_blank">here</a>. EXAMPLE #2 doesn't work fine, I get this: If you dunno, or have no idea, you can try looking up <a href="http://www.here.com]here[/url] or [url=http://www.anotherhere.com" target="_blank">here</a> ! -- Edit bug report at http://bugs.php.net/?id=39624&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=39624&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=39624&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=39624&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=39624&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=39624&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=39624&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=39624&r=needscript Try newer version: http://bugs.php.net/fix.php?id=39624&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=39624&r=support Expected behavior: http://bugs.php.net/fix.php?id=39624&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=39624&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=39624&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=39624&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=39624&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=39624&r=dst IIS Stability: http://bugs.php.net/fix.php?id=39624&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=39624&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=39624&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=39624&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=39624&r=mysqlcfg
