1.  Try  - Catch function :-

Try -
         A function using an exception should be in a "try" block. If the exception does not trigger, the code will continue as normal. However if the exception triggers, an exception is "thrown".
Throw -
       This is how you trigger an exception. Each "throw" must have at least one "catch".
Catch -
        A "catch" block retrieves an exception and creates an object containing the exception information.

Code:-

<?php 
try { 
   $error = 'this error throw everytime'; 
   throw new Exception($error); 

   //Code following an exception is not executed. 
   echo 'This portion is Never executed'; 
 
}catch (Exception $e)
{ 
   echo 'exception message: ',  $e->getMessage(); 
} 

// Continue execution 
   echo '<br>This portion is executed'; 
?> 

Output :-
