So your just trying to find out if the string length is 0 or empty correct?

If so you may want to swap them around because I see here that it may assume your $string is a non numeric character and return false when compared to “0” or “0” will be also used as ” ” an empty space. Nothing compared to something will return a false.

Lets define the Variable $string to store here:
$string = "Your String Goes Here!";

Lets check if the string is empty or equal to 0 here.

   if( strlen( $string == "0" ) ){
  return "";
}
 else{
  return $string;
}

or

   if( empty( $string ) ){
  return "";
}
 else{
  return $string;
}

or

   if( !$string ){
  return "";
}
 else{
  return $string;
}

Remember that if for some reason the Var $string is empty, ”, “”, 0 or “0” they will be read as empty or “0”.

Give those a try. if the error goes away and the string does not output or return try replacing:
return $string;
With
echo $string;

Hope that helped!
