Global Variables

[Peterstephen]

I've got a php file that Contains Functions. This is included into my main script using an include statement

include("func.php").

In my main file I set some Global Variables. These can be seen within the file func.php but not within the functions definded in there.

I want to be able to reference these variables within the functions. Is this possible and how do I do it.

Cheers

<?php

// define a variable
$var = 'foo';

// the function
function glob()
{
   global $var;
   echo $var;
}

// call the function!
glob();

?>

As you may have noticed, you should only use global within functions. Using the keyword global outside of a function does absolutely nothing.

Also note that this is not really good programming practice. If you need a value in a function, pass it in.

Exactly, but now he was asking for the other way... 😉
