ID: 33076 User updated by: sebastianvasile at yahoo dot com Reported By: sebastianvasile at yahoo dot com Status: Open Bug Type: Strings related Operating System: Linux 2.6.3 PHP Version: 5.0.4 New Comment: I think I found what crashes it: I have: str_ireplace("t", "ttttt", "This is a text"); I get: crash. ************************************************ I have: str_ireplace("t", "tttt", "This is a text"); I get: tttthis is a ttttext (final t not replaced) *********************************************** I have: str_ireplace("Z", "zzzzzz", "zThis is a text"); I get: zzzzzzThis is a One more "z" in replacement will crash. ********************************************* Seems like the original string size is not increased. Previous Comments: ------------------------------------------------------------------------ [2005-05-20 15:52:16] sebastianvasile at yahoo dot com I tested this build: May 20 2005 10:18:50 on my WinMe machine. I cannot make a linux test (like the original report) because I cannot administrate the server. It's not working on my machine, it gives an error in Kernel32.dll error. I found a strange behaviour: If I have: "this is a text" and try to replace the "t"'s with something else than it works fine. (but str_replace could be used instead) If I have: "This is a text" (at least one "t" in uppercase) it crashes. It works fine for 2 characters. I hope I'm doing this report right as I don't want to cause more trouble than to help. ------------------------------------------------------------------------ [2005-05-20 11:35:10] sniper@php.net Please try using this CVS snapshot: http://snaps.php.net/php5-latest.tar.gz For Windows: http://snaps.php.net/win32/php5-win32-latest.zip I can not reproduce this. ------------------------------------------------------------------------ [2005-05-20 11:32:57] sebastianvasile at yahoo dot com Description: ------------ str_ireplace is causing a "Page cannot be displayed" when I pass a single letter as $search. Reproduce code: --------------- $value = str_ireplace($keyword, "<font color=\"red\">".strtoupper($keyword)."</font>", $value); I want to use this code for highlighting $keyword found in $value. $value is a large string. It works fine if $keyword has more than one caracter. It works fine if I use str_replace. If I pass only one character I get a Page cannot be displayed Expected result: ---------------- String with characters replaced. Actual result: -------------- The page cannot be displayed, in IE 6.0.2800.1106, on Win Me ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=33076&edit=1
