From: [EMAIL PROTECTED] Operating system: Linux PHP version: 4.0.4pl1 PHP Bug Type: Performance problem Bug description: ereg_replace takes a preposterous amount of time w.r.t. PHP3 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^). -- Edit Bug report at: http://bugs.php.net/?id=11018&edit=1 -- PHP Development Mailing List <http://www.php.net/> To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
