I just made a major booboo! Let me explain: I finished upgrading to PHP version 5.2.6 from PHP 4.2.1, and in my code I use a lot of include() and require() functions to create the page templates. Well, as soon as I restarted my server, those functions stopped working. Even worse is I have literally thousands of pages on my site and practically all of them use these functions in one way or another; these pages are no longer rendering... Is there some sort of setting I need to change or fix in php.ini, or something else, or is there a way to fix this globally? If not, how can I downgrade back to PHP 4.2.1?

Also, I have a MySQL database and for some reason, I can't connect to the database using this code:
CODE
$con = mysql_connect('localhost', 'mysql_user', 'mysql_password');
It just flat out doesn't return anything. Am I doing something wrong here, too?

Please, please, please help me fix my mess catastrophe!! stupid.gif

the mysql code looks fine.

Without some idea of what is in the files, it is really hard to know what isn't working. You may want to check your php.ini file and make sure it is setup to use mysql. Installing a new version will overwrite many old values.

All those functions should work fine in PHP 5.x - I would review your php setup and see if you have configured everything correctly, or just uninstall the lot and install a package like WAMP or XAMPP.

What error messages are you seeing? If you're not getting anything on screen or in your logs, then make you have error_reporting cranked up and display_errors or log_errors turned on in your php.ini. Once we know what the actual error is, it'll be easier to provide a meaningful response.

As for the MySQL, the only compatibility issue that springs to mind is that PHP5 no longer ships with the MySQL extension by default, so you may have to install/enable it separately.

Hi there!

I turned on full E_ALL debugging, but where would I find the error messages? Is there a file on my server that is written to whenever an error happens or something? Where would I find this if there is?

Thanks for your help! biggrin.gif

The logfile would be specified in your php.ini file.

The logfile would be specified in your php.ini file.

Specifically, the error_log setting would indicate the path to the error logs. If error_log is not set, then the errors are probably being sent to the web server's error log.
