global just makes it available within the function, you then call the
variable as normal
using your code:
$j = 0;
function doThis($tempVariable) {
global $myArray;
if ($myArray[$j] == $tempVariable) {
echo "whatever";
}
$j++;
}

Then how wuld I declare the global as the condition of an if?
$j = 0;
function doThis($tempVariable) {
if (global $myArray[$j] == $tempVariable) {
echo "whatever";
}
$j++;
}
Thanks,
