Check string length in PHP

Question

I have a string that is 141 characters in length. Using the following code I have an if statement to return a message if the string is greater or less than 140.

Answer 1

The xpath() function does not return a string. It returns an array with XML elements (of type SimpleXMLElement), which may be casted to a string.

if (count($message)) {
   if (strlen((string)$message[0]) < 141) {
      echo "There Are No Contests.";
   }
   else if(strlen((string)$message[0]) > 142) {
      echo "There is One Active Contest.";
   }
}
