I've successfully added several PHP extensions to my stock, Apple-supplied PHP install on my MacBook Pro. Tonight I wanted to add xdebug to help track down some Drupal OpenID problems. A bit of Google searching and I found a number of examples. Virtually all of them pointed at ActiveState's precompiled xdebug.so binaries, so I tried that.
Command-line (php -m) and (php -i) worked fine after getting my php.ini file correct. But my Apache module never saw the xdebug extension, and that's where I needed it most.
Last year, Australia became the first country to announce it would ban the use of incandescent bulbs by 2010. California is planning a phase-out by 2018. And on Tuesday, New Zealand said it would join the fray, ending the use of traditional lightbulbs starting in October 2009. Now Europe is talking about doing the same.
Do you have a Mac still running Tiger (Mac OS 10.4)? And did you recently decide to install a PEAR component for use with some PHP? And lastly, did it fail with some cryptic HTTP error "410 Gone" that you had very little luck finding with Google? I did.
The solution is a bunch of steps backward and then forward again. Unfortunately, it's not very clear to the perhaps large number of Mac users who did not keep their PEAR libraries up to date all along on Tiger. But the answer is here, at the moment (it will scroll off when more news is added): http://pear.php.net/
I run a couple of Drupal sites on 1and1 for historical reasons (3 years free). A while ago, I dutifully upgraded them to Drupal 5.7. And was surprised to find that PHP's register_globals was enabled.
All this time, I've been running with a .htaccess file which explicitly disabled that setting -- if 1and1's Apache was running mod_php only, it turns out. Apparently, such PHP settings in .htaccess files don't do anything if running PHP in CGI mode.
