Including a Class file causing script to stop

andrewbft

Looking for help with a very strange problem.

I have a DatabaseConnection class stored in a file called db.class.php in the include folder of my site.

I include this using the line

include_once 'include/db.class.php';

When the script hits the Class file it stops there.

Any help with this would be appreciated

You may have something in db.class.php that ends the script execution.
Like exit() or die()
Could be some db connection error for example.

Or you have an error in there. Check php.ini to make sure that error reporting is turned on.

I have checked the file on a local server on my machine and it works fine but when I upload it onto the production server I get the problem.

So i think the file is fine

The production server has php 4.3.7, i think

and the local server has 5.3.1

Would this be the problem?

I have personally had this problem on numerous occasions, and I have to say its one of the most annoying things in the world. It could be the compatibility issue you just mentioned. But you may want to try this as well just in case. What I usually do to see what is causing my class to die is simply comment everything out then slowly comment it all back in. A few lines at a time. That way you narrow down what is causing it until eventually you find what the problem is. In most circumstances I have noticed it is usually nothing more than a small characted missing or something. Like the decimal point when appending a variable to a string. Give it a try, see what happens.

The solution is to use PHP 5 on any machine you use. The PHP4 lifecycle ended last year or something like that. PHP 5 has existed for many years. If you're using a host that still hasn't upgraded to PHP5, or lets you choose which version to use, get a host that isn't seriously horrible.

There were lots of changes in classes, and other things, between 4 and 5. Among other things visibility keywords were added in 5: public, protected and private.
