Quick Question

[Fira]

I've been learning php for a month, and have made decent progress, but seem to have stumbled upon this:

I've an include file, named inc.php. Within it stores many variables, one of which is called $var.
I've another file, named function.php. It includes inc.php. Within function.php is a function named fun().

Would Fun() be able to recognize $var without any direct declarations within the function itself? And what if Fun() was called from another file that includes function.php?

Help is appreciated.

If you set $var as GLOBAL you can use it within the function fun()

[Fira]

And global is only needed for usage of variables within functions?

edit:

Now I'm recieving the error

Parse error: parse error, unexpected '=', expecting ',' or ';' in c:\WEB_ROOT\includes\include.php on line 13

Here's line 13 of include.php:

[quote]

global $epts = (mysql_result($result,0,'ep'));

try

global $epts;
$epts = mysql_result($result,0,'ep');

also, unless you passed $result as an argument ot the function, you're going to have to declare it as a global too.

Better than using globals - pass variables to the function as arguments and use return value.

So define the function as
[code]
fun ($result) {
    $res = mysql_result($result,0,'ep');
    return $res;
}
[/code]

and call with

$epts = fun($result);

Problem solved. Thanks everyone.
