Question

I get the error for the following code

     class Myclass {
              //...variables

              public function getName() {
                       return $this->strName;
              }

              public function checkDup() {
                      if(empty($this->getName())) {  //HERE IS THE ERROR
                        $strMessage = 'Please Enter First Name';
                        return $strMessage;
                      }
              }
     }

     $a = new Myclass (); //assume constructor is present and variables are set in class
     $a->checkDup();

What could be the solution?
My getName() function returns the name of the variable

I figured out what was going wrong here.

I should be referring to the class member variable using $this and not call the getName() function again inside the class. This changes the function to :

          public function checkDup() {
                  if(empty($this->strName)) {  //HERE IS THE SOLUTION
                    $strMessage = 'Please Enter First Name';
                    return $strMessage;
                  }
          }
