Global doesn't CREATE global variables, it allows variables to be used as
globals. For example, in the above setup, you would do this instead:
function setGlobal() {
global $test;
$test = "123";
return $test;
}
$test = setGlobal();
function getGlobal() {
global $test;
echo $test;
}
And now, getGlobal will echo $test as:
123
Of course, if you are looking to create global variables in a single
function, then you simply would do something like this:
function setGlobal() {
global $test;
$test[0] = "123";
$test[1] = "456";
$test[2] = "789";
return $test;
}
and that would return the array $test, and therefore:
$test = setGlobal();
$test would be an array, and then you could set global in any function $test
and be able to use multiple values (as per the array). This is easier than
globaling 20 or so values you may need.
