FYI, I just ran a quick scope test based on my guess of your
situation. If you include a PHP file containing global variables
inside a function, the variables will _only_ be available after you
include the file, and only for the duration of the function. They
will not exist after the function ends, even if you specify global
$var1; in your other functions, or at the global level of your script.
This was tested using PHP 5.0.4.
Here is my sample code:
test.php:
<?
print "Top Level: Var1: $var1 Var2: $var2\n<br>";
test1();
test2();
function test1 ()
{
print "Before: Var1: $var1 Var2: $var2\n<br>";
include("testinc.php");
print "After: Var1: $var1 Var2: $var2\n<br>";
}
function test2 ()
{
print "Test2: Var1: $var1 Var2: $var2\n<br>";
}
print "Bottom Level: Var1: $var1 Var2: $var2\n<br>";
testinc.php:
<?
$var1 = 1;
$var2 = 2;
?>
