Answers: How do I downgrade php from 5.4 to 5.3 in CentOS?

andekhi

I have a webserver running CentOS 6. Yesterday, I installed php-gd with yum install php-gd because I couldn't see graphics on my website. However, when I see my php version, it changed from 5.3 to 5.4x.

Because my application uses register_globals (which was removed from php 5.4), I cant even log in to my app.

I tried two ways to downgrade my php:

Using yum again to downgrade; this wouldn't downgrade to 5.3x, just 5.4x
Downloading the php rpm directly; I messed this up, and wound up with dependency hell.

Why not simply fix your code - According to http://ubuntuforums.org/showthread.php?t=1973028 add the following to the top of your PHP script -

foreach ($_REQUEST as $key=>$val) { ${$key}=$val; }

(And ask yourself why you are running insecure code).

Apparently you can even automate this further by adding an "auto_prepend_file" directive to a .htaccess file to make it work for the entire directory in 1 hit.

 You could try using --skip-broken to work around the problem
 You could try running: package-cleanup --problems
                        package-cleanup --dupes
                        rpm -Va --nofiles --nodigest
The program package-cleanup is found in the yum-utils package.
