Can't extend php class

Question

I'm trying to move a php/mysql web application to a new server. The application runs fine on multiple other servers, just not the one the client wants it on. Problem 1 is I can't get errors to display on screen or in an error log. (I've posted a separate question about this). I'm hoping if I can get error to display I'll have more to go on, but what I know so far is it fails when trying to extend a module. I stripped down the class to just this:

class Module_Organization extends LmsModule {
    function Module_Organization($module_name = '') {
        die('Made it into the function');
    }
}

Nothing happens. But if I change it to:

class Module_Organization {
    function Module_Organization($module_name = '') {
        die('Made it into the function');
    }
}

then it does execute the die statement. So it seems that the extend portion is tripping it up. But I don't think it's the code because I know this exact code works fine on other 5 other servers. So I'm wondering if there is any server configuration that could prevent php from extending a class.

Thank you in advance for your help.

Answer 1

I compared the php.ini file to a server where it is working to make them match and it is now working. I'm not sure which changed fixed it though. Thank you.
