Hey Guys,
I need to make a local function variable into a Global variable for access outside of the function in PHP. I have a feeling if i figured out classes i would be able to do it without using functions but currently i need them.
Any ideas?
Thanks,
Speed

Is there a reason you can't return the variable from the function itself to use it? If you can't simply return the value, I would look to see if using a class made sense. If you don't want to mess with classes then you can make the variable global in scope (see this page)

I recomend using a function with return() as flareback stated. Though it is possible to do what you want... here are some examples:

<?php
// Example 1 - Return value from function
$test_1 = testFunction1();

function testFunction1(){
	return '1';
}
$test_1 += 1;

echo 'Output of test 1:<br />';
echo $test_1; // outputs '2'
echo '<br /><br />';


// Example 2 - Declare global using variable outside of function
$test_2 = 100;
testFunction2();
function testFunction2(){
	global $test_2;
	$test_2 += 99;
}
$test_2 +=1;

echo 'Output of test 2:<br />';
echo $test_2; // outputs '200'
echo '<br /><br />';



// Example 3 - Declare global using variable inside of function
$test_3 = 9999;
testFunction3();
function testFunction3(){
	global $test_3;
	$test_3 = 4;
	$test_3 += 1;
}
$test_3 += 5;

echo 'Output of test 3:<br />';
echo $test_3; // outputs '10'
?>

I had totally forgotten this thread existed, i went the route suggested by flareback.
Thanks all.
