  2. $a = "joe";
  3. $b = "jerry";
  4. if ($a != $b)
  5. {
  6. echo "not equal";
  7. }
  8. else
  9. {
  10. echo "Equal";
  11. }
  12. ?>

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.

  2. echo strnatcmp("10.gif", "5.gif"); // Return 1 (>0)
  3. echo strnatcasecmp("10.gif", "5.gif "); // Return 1 (>0)
  4. ?>
