The prbolem is variable scope.
function foo(){
$x = 'HELLO WORLD!';
}
foo();
echo $x; // Print's nothing
Regardles of $x being assigned at foo(), nothing is echoed. Why? 'cos $x
belongs to variable scope of foo(), not main.
Solutions:
Bad solution: make $x global. Quick and dirty, don't try this at home.
Good solution: make the function return an array of errors and use the
returned array values to echo error messages.
