PHP: variable not working inside of function?

Question

echo $path; //working
function createList($retval) {
    echo $path; //not working
    print \"


        

Answer 1

As an alternative to using a global variable, just pass $path in. Of course, if you don't need the variable inside the function, don't bother!

echo $path;
function createList($retval, $path) {
    echo $path;
    print "";
    foreach ($retval as $value) {
            print "$value
";
    }
    print "";
    print "";    
}
