Hello,

I needed to downgrade php from 5.3 to 5.2.13 on Snow Leopard and did the following after installing macports:

1. sudo port uninstall php5 (seemed to run quickly with no error)
2. port install php52 +mysql5 +apache2(ran successfuly)
3. port variants php52 (ran and produced the following:

In the future, please review WikiFormatting and Cc the port maintainers.

This is not appropriate for Trac, but I'm assigning it to the php port maintainers and they can decide.

How did you determine that this is the case?

Does port installed php52 show that php52 is installed and active?

What does /opt/local/bin/php -v say? On my system, when php52 is installed, it says

PHP 5.2.13 (cli) (built: Jul 17 2010 14:32:26) 
Copyright (c) 1997-2010 The PHP Group
Zend Engine v2.2.0, Copyright (c) 1998-2010 Zend Technologies

If we are talking about using php52 in a web server (e.g. within apache2), have you restarted that web server?

Ryan, Thanks for your response, I think we're close to finding the solution, here's what's up...

1. I have a test.php file that contains the phpinfo command and when it runs it says that the php version is 5.3.1.
2. When I run the two commands you specified, I get the results you expected:

   dfmacbookpro:~ dforrest$ port installed php52
   The following ports are currently installed:
     php52 @5.2.13_2+apache2+mysql5 (active)
   dfmacbookpro:~ dforrest$ /opt/local/bin/php -v
   PHP 5.2.13 (cli) (built: Jul 17 2010 00:59:37) 
   Copyright (c) 1997-2010 The PHP Group
   Zend Engine v2.2.0, Copyright (c) 1998-2010 Zend Technologies
   

3. I have restarted apache numerous times and have rebooted the machine too and still get the same results using phpinfo command, version=5.3.1.
4. httpd.conf for apache has "LoadModule php5_module libexec/apache2/libphp5.so"
5. Should #4 point to somewhere else? It's obvious according to #2 that 5.2.13 is installed, but, apache seems to still be using 5.3.1. Any ideas how to correct this?

Thank you very much,
David

David, remember to enter your replies into the ticket on the web site; replies sent by email do not become part of the ticket comments.

I suspect you are using Apple's Apache and not MacPorts' Apache. Turn off Apple's Apache (System Preferences > Sharing > Web Sharing) and turn on MacPorts' Apache (set up /opt/local/apache2/conf/httpd.conf as desired, then type "sudo port load apache2"). Don't use Apple's Apache if you want to use Apache modules supplied by MacPorts.

Ryan, Thank you SOOOOOOooooooo much for your help. Using the apache2 from macports did the trick along with a little httpd.conf tweaking. Is there a command I can run that will ensure that on reboot the machine will launch the macports apache instead of the apple one? Thanks again, David

You have already run the command: "sudo port load apache2" launches MacPorts apache2 immediately and schedules it to launch at every subsequent system startup. To stop MacPorts apache2 immediately and prevent it from launching on startup in the future, run "sudo port unload apache2". MacPorts just installs normal Apple launchd plists, so you can also use "sudo launchctl" directly if you prefer, or a 3rd-party launchd plist manager. (​Lingon used to be nice for this, but has been discontinued and I don't know if it works with current versions of Mac OS X anymore.)
