Just upgraded php on CentOS 5.8 To find your version type:
I used the following link on how to upgrade old versions of CentOS to more current PHP/MySQL.
The upgrade was smooth except that ESL for PHP stopped working. Following error when trying startup PHP.
PHP Warning: PHP Startup: ESL: Unable to initialize module
Module compiled with module API=20050922
PHP compiled with module API=20090626
These options need to match
in Unknown on line 0
Doing the following should have resolved the issue but it didn't work.
When I removed the old version of PHP it must have removed one of the dependencies. The compile error message indicated that I need to install libtermcap
yum install libtermcap.i386
yum install libtermcap-devel
The libtermcap.i386 was already installed but the devel wasn't.
After this make completed properly and everything was back to normal.
Note: The above make commands are correct. The "make phpmod-install" is the way it should be done.
If you do "make phpmod install" it will fail. This can be easily confused if you are doing things really fast.
