how about this sample php code:

<?php
$str = "10";
$num = (int)$str;
echo $num * 5;
?>

in addition, did you know you can use is_int() function to find out whether the type of a variable is integer or not. here's an example:

if (is_int($num)) {
echo "is integer\n";
} else {
echo "is not an integer\n";
}
