I would suggest to use this default value and try again. the exact same bug occurs whatever the limit set.

Re: [PHP-DEV] how to find a memory corruption in php ?
hi, In php 5.3+ the memory limit default is 256MB, not 128MB. 5.3 does not necessary use more memory but actually uses and reports its usage more efficiently. I would suggest to use this default value and try again. About detecting leaks and memory corruptions, valgrind is a good tool to begin with.

[PHP-DEV] how to find a memory corruption in php ?
Hi all, I get an error with my program: Fatal error: Allowed memory size of 134217728 bytes exhausted at /home/courtois/php-5.3.6/Zend/zend_execute.h:163 (tried to allocate 261900 bytes) in /var/www/dev4.sociatomdev.com/chroot/htdocs/templeet/fetch.php on line 580 - The same error occurs with any of php 5.3 versions tested. With 5.2 it's ok. - I know the error message is wrong. The program does not consume much memory. - If i change some lines in my php code like adding trace messages it sometimes work sometimes no (but constant result for same php code) I will not submit the bug since it's hard to reproduce unless being in the exact same configuration as me. I used to be an experienced C programmer (>30 lines written) but almost nothing for the last 15 years. My questions: - is there any document somewhere to read before hunting a bug in php ? - are there any build/compile options other than --enable-debug ? - how should I proceed to debug when php is called via fastcgi ? My configuration: debian squeeze i386 32bits Thanks, Pascal -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP-DEV] Adding a more logical string slicing function to PHP
> string substr( string $string, int $start [, int $second [, int $flag = > SUBSTR_LENGTH ]]) I think this just makes code ugly. I think a new function with something like 'slice' in it is pretty unambiguous and unconfusing. (I also like the current substr() semantics. Actually, I think 'slice' is the new kid on the block, and has only really come up in the last 10 years or so as web tech and scripting languages have grown. Before that, in C and BASIC and so on, semantics like substr() has were more common--at least for positive numbers. But that's neither here nor there.) Ben.

Re: [PHP-DEV] Adding a more logical string slicing function to PHP
Hi all, I just come back on the first reflexion about adding a str_slice() function. As it says before, using one method or the orther can really sucks in some cases, depending what you are coding about. So actually you mention there is two possibility : - Keep all in the actual state. substr is allready quite cool but can suck in some case. - Add a new function and a create a possible confusion about the two method name (like javascript), etc... bad idea. In fact I see a third possibility, change the substr() function to handle the both case.
