What will be the output for the below code?

for ($col = 0; $col < $highestColumnIndex; ++ $col) {
    $cell = $worksheet->getCellByColumnAndRow($col, $row);
    $val = $cell->getValue();
    echo "Print Value is: ".$VAL;   
}

OUTPUT:

Notice: Undefined variable: VAL in C:\xampp\htdocs\trunk_release_cycle04\application\importstatus.php on line 28

SOLUTION:

Variable name in PHP is case-sensitive. Replace $VAL into $val.
