Declaring a variable to be global in a function call argument will cause a parse error.
RIGHT:
<?php
$a = 1; // global scope
function test() {
global $a;
echo subtest($a); // works
}
function subtest($argument) {
return $argument + 1;
}
test();
?>
WRONG:
<?php
$a = 1; // global scope
function test() {
echo subtest(global $a); // results in parse error
}
function subtest($argument) {
return $argument + 1;
}
test();
?>
