If you Get this Error (Fatal error: Call to undefined function: mysql_connect())
Check your Log files..
I was getting these Error Messages too,which was the main cause.
PHP Warning: Unknown(): Unable to load dynamic library '/usr/lib/php/domxml.so' - /usr/lib/php/domxml.so: cannot open shared object file: No such file or directory in Unknown on line 0

PHP Warning: Unknown(): Unable to load dynamic library '/usr/lib/php/pgsql.so' - /usr/lib/php/pgsql.so: cannot open shared object file: No such file or directory in Unknown on line 0
The Reason that we are getting these Errors is very simple.
The PHP4 is not able to read the files mysql.so,..and the others.
The simple change that I made was just to rename the folder from /usr/lib/php4 to /usr/lib/php.
