Create a new file info.php write it in Phpinfo (); Print out detailed information. See if the MySQL extension is loaded first. And then say the rest.

Run the test under the terminal with non-root permissions php index.php To troubleshoot the permissions issue. By the way, the PHP error fully open to see if it was recorded by log

Open the error first to see what is wrong, it looks like death in Mysql_connect

Re-install lamp, now it's ready

The next time you use other resources, you can try this mysql_connect (...) or Die (Mysql_error ());
