Challenge: Exception Handling

Task

You are given a User class with the methods that set and get the user name and age.

• Add code to the setName() method that throws the exception “The name should be at least 3 characters long” whenever the user’s name is shorter than 3 letters.
• Add code to the setAge() method that throws the exception “The age cannot be zero or less” whenever the user’s age is less than or equal to zero.
• In the test() method, feed the class with this nested array:

  $dataForUsers = array( 
   array("Ben",4),
   array("Eva",28), 
   array("li",29), 
   array("Catie","not yet born"), 
   array("Sue",1.5)
  );
  

• Write a foreach loop (like the one we’ve already used in this chapter) that feeds the array to the class and handles the exceptions by echoing the custom error messages as well as the file path in which the exception was thrown.

Expected output

Ben is 4 years old. Eva is 28 years old. Error: The name should be at least 3 characters long in the file: /usercode/main.php. Error: The age cannot be zero or less in the file: /usercode/main.php. Sue is 1 years old.
