Hmm... I was able to configure and make 5.0.4 with GD without problems. What version of PHP are you building? Can you provide the entire ./configure line? Have you installed the new version of Xcode from the 10.4 DVD? - Gabriel -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php

Same here. I have a number of static arrays that I use for reference data that are usually encapsulated in a function, or a global / session variable. It would be very handy to be able to define a constant array instead. - Gabriel = -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php

"ugly" is a subjective argument and does not change the usefulness of that particular ability. Where would the C language be without the ability to define arbitrary constant values? - Gabriel = -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
[PHP-DEV] Microsoft Scraping Email Addresses From PHP Internals List?
I know it's off topic, and I appologize, but I lurk on this mailing list using a disposable address to avoid spam, and now I'm receiving it as a result of being on the list (or posting to it). I have now received three separate Microsoft emails (security updates and such) at this address, which is only used for sending and receiving mail from the list. Pretty annoying for someone who doesn't use their products. Thankfully I can just whip up a new address and resubscribe, but I figured I'd let you folks know in case you're receiving the same crap. - Gabriel = -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php

[PHP-DEV] intercepting function calls

I'm mostly just curious, but I may actually create an extension to provide user space ability to intercept function/method calls and execute code before / after them. I made a comment about the Aspect Oriented PHP article on /. back in January that it'd be better to implement that type of call interception within PHP itself, not using some kind of preprocessor. The damn idea's been stuck in my brain ever since. So, just to be clear... Will using call_user_function() either from the hooks or a zend_execute() wrapper cause any problems in the zend engine? - Gabriel = -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP-DEV] Creating a Module
