PHP equivalent of Java Character.getNumericValue (char c)?

Question

Is there a PHP equivalent of Java Character.getNumericValue(char c)?

Answer 1

No. There is no baking in equivalents.

Answer 2

Use the function intval().

This will not handle letters or roman numbers the same way, but you can create your own method for this. However, it will handle standard numbers.

if (intval ("2") === 2)
  echo ("YAY!");

    return ord($ch) - ord('0');
  if (ctype_upper($ch))
    return ord($ch) - ord('A') + 10;
  if (ctype_lower($ch))
    return ord($ch) - ord('a') + 10;
  return -1;
