自定义config.php问题

Question

I have been dropped in the deep end by being asked to migrate an OLD custom built website (using php and mysql) to another server. I have changed the config to reflect the new location but all I get is a white screen. The DB connects fine so that isn't the issue, I think it might be with the $doc_root. Can anyone help with the code below?

$doc_root = str_replace( '\\', '/', substr($_SERVER['SCRIPT_FILENAME'], 0, 0-strlen($_SERVER['PHP_SELF'])))."";
$DOC_ROOT = str_replace( '\\', '/', substr($_SERVER['SCRIPT_FILENAME'], 0, 0-strlen($_SERVER['PHP_SELF'])))."";

I dont know php too well unfortunately so I am stuck! The current test server address is in this formathttp://xx.xxx.xx.xx/thedomain.com/

I have tried so many combinations of the above for the $doc_root but whatever I do won't work.

Can anyone help? Thanks in advance!

Answer 1

Edit your php.ini file and enter the following line:

error_reporting = E_ALL

This will report the exact error as to where your code is going wrong instead of a blank page.

Another method is to run the the command

$php <php-filename>

If you report the error here, maybe then one can help you more.
