Using Include Files and Classes

[Michael42]

I have a file that contains my Application class. I want to have an include file that will make it easier to set the instance variables. So I made an include called config.php.

I use includes for other things (headers\footers) so I think I have the syntax right:
include 'config.php';

If I move my code to the include with my instance variables and create an include directive to it from the page with my classes it does not work. Blank screen etc.???

What can you recommend?

Thanks,

Michael42

Difficult to say.

What have you done to test?

Bascially just move the code back and forth between being in my file that houses my Application class and to my config.php include file.

Instance variable declarations seem to only work when not in an include.

Thanks for the response,

Hey maybe this is it. My include file with class instance variables is at a second tier, i.e., it represents an include file that has an include.

Is that OK in PHP?

Included files and themselves include files.

Just to ask the dumb question...

Does your include file code have <?php...?> tags around it?

Is this cool in PHP?


I tried <?...?>, <?php...?> and none at all.
No joy. :-(

Thanks for the suggestion though,

Sorry, I got my grammar messed up.

Yes, it's all right for an included file to itself include another file.

If you're included file contains code, you're going to need <?php...?> tags as appropriate. An included file reverts PHP's interpretation back to HTML mode.


Have you viewed the source of the HTML produced? There might be something in there that can give you a clue, but malformed HTML tags are preventing you from seeing it on the browser.

What is your error_reporting setting? There might be an error that PHP has been told to not report.

Are you making use of the &quot;@&quot; error-suppression operator? That could be preventing errors from being displayed.

shouldn't it be

include('config.php');

?

KempCGDR:

include, include_once, require, and require_once are language constructs, not functions. As such, the parentheses are not required.

This is similar to echo or print.
