I've a server running Centos 5. Yesterday I upgraded php to 5.4.10 throught remi repository. Operation was successful ( I've checked updated information in phpinfo()) Today I figured out that php launched from shell, displays a different version (5.2.16). This version is the previous one. If I do

which php

output is: /usr/local/bin/php while the new php 5.4 binary is /usr/bin/php

From what I understood, php was manually compiled in the system and there are no source installation files around.

How can I change the path usr/local/bin/php to /usr/bin/php. I dont'k know where to look for.

Just try removing the PHP that was installed to /usr/local. – Michael Hampton Jan 12 '13 at 17:34
I've already done it, but with no luck. php from command line stopped working until I created a symlink ln -s /usr/bin/php /usr/local/bin/php. Btw symlink is not a solution because other commands rely on that path such as pear command. so I need to change this path at the root (I'd like to know where this path is stored in). – cardy Jan 12 '13 at 18:07
Just log out and log back in. – Michael Hampton Jan 12 '13 at 19:13

After digging into documentation and others great Linux stuffs I've found the solution. All depends from $PATH environment variable, specifically from the order of the directory listed in.

#original $PATH
echo $PATH

So, I moved /usr/local/bin at the end of the string, and everything start working again:

export PATH=/usr/bin:/usr/sbin:/bin:/sbin:/usr/local/bin

Now I've to make this edit persistent, because export instruction expires with session end.
