PHP :: Bug #18826 :: slow string search (strpos,ereg etc.)

[2002-08-09 04:05 UTC] potsataja at future dot 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.

Can you please try a CVS version?  I believe this is/has been  addressed already, but I'm unsure.

nope, thats impossible, because its a public server with many clients.

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...

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.
