Thought of sharing this with everybody.

While trying to compile PHP 5 with mysql and mysqli , I was facing some issues.
Actually, the configure command generates a bad Makefile.
Open the Makefile and look for a line staring with EXTRA_LIBS

You will see that the option “-lmysqlclient” is repeated twice. Delete one of them and save the Makefile.

Now, you should be able to run the Make command and compile PHP without any issues.
