#18826 [Fbk]: slow string search (strpos,ereg etc.)

ID: 18826 Updated by: kalowsky@php.net Reported By: potsataja@future.ee Status: Feedback Bug Type: Strings related Operating System: linux, redhat 7.2 PHP Version: 4.2.2 New Comment: Okay lets try this again. 1) A simple sample script. Give us the most basic sample script you can create to reproduce this. 2) Even with your sample scripts I don't see any real slowness to it. You need to quantify the word slow. Off my DSL line your page loaded up fairly quickly once your DNS was resolved. Previous Comments: ------------------------------------------------------------------------ [2002-08-15 01:48:43] potsataja@future.ee sample working script http://potsataja.aasa.ee/bug/index.php script source http://potsataja.aasa.ee/bug/index.php?show=1 template file http://potsataja.aasa.ee/bug/template.htt hope it helps.. ------------------------------------------------------------------------ [2002-08-14 18:28:03] kalowsky@php.net Then give me a full sample script in the simplest form to reproduce this. As your posted code only returns what I've passed into it. Even at that, this takes a minimal amount of time to execute as a debug build... ------------------------------------------------------------------------ [2002-08-14 05:04:11] potsataja@future.ee nope, thats impossible, because its a public server with many clients. ------------------------------------------------------------------------ [2002-08-13 21:56:24] kalowsky@php.net Can you please try a CVS version? I believe this is/has been addressed already, but I'm unsure. ------------------------------------------------------------------------ [2002-08-09 04:05:39] potsataja@future.ee Hi, i just upgraded php in my server to 4.2.2 and then problem began. I use my own html parser (function at the bottom), what parses with new version php very slow. I also found problem, it seems that ANY string-search function is slower then in a older version. ------------------------------------------------ function ParseData($f,$v) { if(defined("SID")) { $v["SID"] = SID; } $n = 0; while($s = strpos($f, "{", $n)) { $e = strpos($f, "}", $s); if(!is_int($e)) { break; } $d = substr($f, $s+1, ($e - $s - 1)); if(!preg_match("/[[:space:]]+/", $d)) { $f = str_replace("{".$d."}", $v[$d], $f); } $n++; } return $f; } --------------------------------------- i also tryd strpos function, what should be faster then regexp search but it doesn't.
