PHP 4.0 Bug #8945 Updated: include, require, et al.

ID: 8945 Updated by: sniper Reported By: Jason@hspace.net Old-Status: Feedback Status: Closed Bug Type: Performance problem Assigned To: Comments: No feedback. --Jani Previous Comments: --------------------------------------------------------------------------- [2001-02-17 13:09:27] sbergmann@php.net You say that you use conditional statements to determine whether or not to REQUIRE a file. Just to make sure: You're not using require or require_once inside a conditional block, such as: <?php if($condition) { require "some_file.php"; } ?> I'm asking this, because require and require_once are UNCONDITIONALY called, see the manual pages for require and include on this topic. --------------------------------------------------------------------------- [2001-01-26 18:58:49] Jason@hspace.net I discovered that the include(), require() or include_only(), require_only() functions have a profound effect on performance. I use conditional statements to conditionally require files, however, it seems that the PHP interpreter has a performance problem with this. Commenting out all the require() or include() code shows that performance improved by 200%. Web Stressing the app and PHP, I have found that PHP can sometimes crash with an Access Violation at 12345 and CPU usage maxing at 100%. Memory leaks very much when CPU usage is at maximum threshold. Zend Optimizer seems to reduce performance by a noticeable amount. It does not seem to reduce CPU usage, unfortunately. I got the best performance from PHP using page cacheing. Results seem to show that it's faster than static HTML... --------------------------------------------------------------------------- ATTENTION! Do NOT reply to this email!
