calling a variable outside a function

[dazed]

I have it set up like this.

index.php (main page, includes all the pages for the site)
codes/main.php (has the functions for the top and bottom parts of the pages)
codes/backbone.php (has the settings for the database and the site than has all the functions not in main.php)

how can I call a variable from a function that isn't in the function. I'm trying to call variables from backbone.php inside of the header function in main.php.

Your variables will have to be global if you want to access them in all of your functions without having to pass them around. This isn't a good design.

You should figure out what variables a function needs and then figure out how to uses them best. If your main.php needs a database connection then you'd better have index.php create the connection (using backbone.php) and then pass that connection into the functions in main.php that need it.

Yeah my design is something I lack in big time. I'm trying to figure that out now by doing this. Thanks. But this is just a little sample code I made, it just shows what i'm trying to do with GLOBAL.

<?
GLOBAL $r;
$r = "blah";

function testtest($somevar) {

	print "$somevar <br>";
	print "$r";

}

testtest("hehe");
?>

it will only print out the $somevar why won't it print out the $r var?

Change:

&nbsp;&nbsp;GLOBAL $r;
&nbsp;&nbsp;$r = "blah";

&nbsp;&nbsp;function testtest($somevar) {

to

&nbsp;&nbsp;$r = "blah";

&nbsp;&nbsp;function testtest($somevar) {
&nbsp;&nbsp;&nbsp;&nbsp;GLOBAL $r;

and you should be in business.
