#23268 [Opn->Fbk]: str_replace total system overload

ID: 23268 Updated by: pollita@php.net Reported By: nick at netdupe dot com -Status: Open +Status: Feedback Bug Type: Performance problem Operating System: Linux PHP Version: 4.3.1 New Comment: Significant portions of the str_replace function are rewritten in the development branch. Can you try downloading a snapshot of PHP-5.0-dev and seeing if the problem persists? I'd also like to ask you to try the latest snapshot of the stable branch. PHP-4.3-stable http://snaps.php.net And incidently your first example shouldn't come up with any error, it should simply fail to replace anything (str_replace is case-sensitive) Previous Comments: ------------------------------------------------------------------------ [2003-04-18 17:07:56] nick at netdupe dot com ok this is the code i used it with: <? $file = file("smillies.db"); foreach($file as $value){ list($rand,$code,$image) = explode("|<|", $value); $code = stripslashes($code); $fusnewsm = str_replace("$code","<img src=\"http://images.devdino.com/smillies/$image\" border=\"0\">",$fusnewsm ); } ?> You will need smilies.db you can get it from www.devdino.com/smillies.db. ------------------------------------------------------------------------ [2003-04-18 09:40:03] magnus@php.net I could not reproduce it with exactly that code. Tried both 4.3.0 and current PHP_4_3 branch. ------------------------------------------------------------------------ [2003-04-18 06:33:06] nick at netdupe dot com got a little mistake in there, "shoudnt it come up?" should be "shoudnt it come up with an error?" ------------------------------------------------------------------------ [2003-04-18 06:31:38] nick at netdupe dot com If you accidently put something like the following in str_replace the server goes nuts and does not return any information. <? $code = "hello"; $string = "Hello, Bob how are you"; $text = str_replace("$code", "hey", $string); ?> This only occurs when you put $code in quotation marks. Shouldnt it come up? I did this the server load went from 0.05 to 23.4 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=23268&edit=1
