Previous Comments: ------------------------------------------------------------------------ [2004-06-23 04:40:49] slunta at msn dot com 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 this bug report at http://bugs.php.net/?id=28886&edit=1
