#28886 [NEW]: line breaks in textareas forces preg_replace to quit

From: slunta at msn dot com Operating system: Linux PHP version: 4.3.6 PHP Bug Type: Output Control Bug description: line breaks in textareas forces preg_replace to quit Description: ------------ I don't know why, or how, but it appears that a line break in a textarea will cause a preg_replace to quit. Let me show you the code and the page so you can test it and see for yourself what I'm talking about. You can find the page with the code at: http://turkeybot.olddh.com/bug.php Reproduce code: --------------- <? $message=isset($_POST['message']) ? htmlentities($_POST['message']) :''; $array1=array('/&lt;b&gt;(.+)&lt;\/b&gt;/','/&lt;i&gt;(.+)&lt;\/i&gt;/','/&lt;u&gt;(.+)&lt;\/u&gt;/'); $array2=array('<b>$1</b>','<i>$1</i>','<u>$1</u>'); $mess=preg_replace($array1,$array2,$message); echo '<html> <form action="bug.php" method="post"> ' .$mess. ' <textarea name="message" cols="40" rows="10"></textarea> <input type="submit" name="post" value="Post" /><input type="reset" name="reset" value="Reset" /></form>'; ?> Expected result: ---------------- When I post the data, I always expect to see my <b>,<i>,and<u> tags to run correctly and display the message with the proper html. Actual result: -------------- The preg_replace fails in replacing the entities with the proper tags once a line break is inserted into the textarea. -- Edit bug report at http://bugs.php.net/?id=28886&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=28886&r=trysnapshot4 Try a CVS snapshot (php5): http://bugs.php.net/fix.php?id=28886&r=trysnapshot5 Fixed in CVS: http://bugs.php.net/fix.php?id=28886&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=28886&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=28886&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=28886&r=needscript Try newer version: http://bugs.php.net/fix.php?id=28886&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=28886&r=support Expected behavior: http://bugs.php.net/fix.php?id=28886&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=28886&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=28886&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=28886&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=28886&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=28886&r=dst IIS Stability: http://bugs.php.net/fix.php?id=28886&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=28886&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=28886&r=float
