If you want to see if a variable has a length of 10:
if (strlen ($variable) == 10)
{
//yes it is
}

Just a small side-note: strip the whitespace at the beginning and end of the variable, too, if you're trying to limit public user input. Example:

  if (strlen(trim($text)) == 10) {
    // do stuff
  }
