$a = "joe";
$b = "jerry";
if ($a != $b)
{
echo "not equal";
}
else
{
echo "Equal";
}
?>

If you use !==, === to compare, the types of the two objects must be strictly equal to return true; otherwise, use ==, != will automatically convert the string into the corresponding type for comparison.

echo strnatcmp("10.gif", "5.gif"); // Return 1 (>0)
echo strnatcasecmp("10.gif", "5.gif "); // Return 1 (>0)
?>
