I’ve looked through the PHP documentation and it seems like this is possible, but it’s still dropping my variable values with global. Is there something I’m missing?

I set $var to a value. Then declare it global $var. Then the value shouldn’t change and I will be able to use it globally right? Forgive my ignorance, I’m new to this.

    The global keyword does not make a variable global, it makes the variable accessible in the context of a function.

    If you want to make a variable global you can use the $GLOBALS array

    From the Manual:

    The $GLOBALS array is an associative array with the name of the global variable being the key and the contents of that variable being the value of the array element. Notice how $GLOBALS exists in any scope, this is because $GLOBALS is a superglobal. 

    $GLOBALS['myvar'] = 'test'; // $GLOBALS['myvar'] can now be accessed in any scope
