This problem occurs in php version 5.2.x (x=0,4,5), but not in version 4.4.7 or 5.1.6. When I upgraded my server to 5.2.5, I discovered this problem. Of course, I first searched for a solution on the phpBB forum, but I found nothing related to this. Am I the first using an older phpBB forum with a new php version, and long texts between tags? Reproduce code: --------------- type message in a phpBB2.0.x forum: [u]012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789[/u] includes/bbcode.php, function bbencode_second_pass($text, $uid): $text = str_replace("[u:$uid]", $bbcode_tpl['u_open'], $text); $text = str_replace("[/u:$uid]", $bbcode_tpl['u_close'], $text); the first str_replace goes well, the second one makes $text empty. Expected result: ---------------- both string replacements are done well and the message is shown. Actual result: -------------- the second string replacement makes $text empty and no message is shown. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=43602&edit=1
