PHP Accessing a global variable inside a class method

[mweinberger]

Hi,

 

I have the following files:

 

/index.php

/Scripts/Header.php

/Scripts/ClassContact.php

 

The Header.php is a file that contains other include files and global variables / constants, such as the following:

 

global $MyConstant1 = 100;

 

The header file gets included at the top of every file on the site, such as:

 

require( "./Scripts/Header.php" );

 

The other file, ClassContact.php, is a file that contains a PHP class that the index file instantiates, i.e.:

 

$objContact = new ClassContact();

 

Inside the class there is a public method. I would like to access the global variable, but alas I cannot. I have to re-include the file in the method. Why is that? In this one particular case, I cannot include the specific file again, because the PHP system seems to know of the previous inclusion and now objects, just the variable does not display its contents.

 

I hope that you are following. Thoughts?

 

Thanks in advance,

 

Sarah

Don't use global variables.  If you have to, you're doing it wrong.

If you are going to the trouble of writing a class, do it properly and don't pass it values using the global keyword. Pass values either in the class constructor or using a specific initialization class function.

 

For your existing problem, the global keyword only has meaning when it is used inside of a function. global $MyConstant1 = 100; has no meaning at all. If you have not researched what the global keyword is or how it is used, then don't use it.

I only thought of using the global keyword to solve the problem. Up until about an hour ago or so, I was not prefixing global. I merely want the class member to see a variable defined outside the class. How do I go about that? Is that possible?

 

thanks in advance.
