ID: 11018 Updated by: brianlmoon Reported By: [EMAIL PROTECTED] Status: Open Bug Type: Performance problem Operating system: PHP Version: 4.0.4pl1 Assigned To: Comments: What is that second regex doing? It looks like there is a missing \ in there. Just for testing, have you tried using preg_replace instead of ereg. The preg functions are faster and more reliable. Previous Comments: --------------------------------------------------------------------------- [2001-05-22 09:50:52] [EMAIL PROTECTED] I suggest using preg_replace and try to splitup the $bib variabele into smaller parts (i.e. per line). Can you see if this works better for you? Derick --------------------------------------------------------------------------- [2001-05-22 09:45:22] [EMAIL PROTECTED] My publication page (http://gongolo.usr.dsi.unimi.it/~vigna/papers) is generated with PHP. Part of the generation process includes the following regular expression substitutions: $bib = ereg_replace("([0-9]+)--([0-9]+)", "\1-\2",$bib); $bib = ereg_replace("{((['`]|w)+)}", "\1", $bib); $bib is a variable containig about 20K of text generated by a BibTeX style. Everything worked fine with PHP 3, but since I installed PHP 4, the page is output in >20 seconds. Indeed, there where other 10 substitutions, and initially the page wouldn't simply display because of server timeout. I changed whenever possible ereg_replace to str_replace, but of course the two substitutions above need regular expressions. They increase the page serving time of about 15s. Computation time was negligible with PHP 3. The strange thing is that the page is _serverd_ slowly. One would expect that there is a long wait, and then the page is served all at one time. Instead, there is a long wait, and then the page is served slowly. Eliminating the two regular expressions above solves the problem (but serves the wrong page 8^). --------------------------------------------------------------------------- ATTENTION!
