PHP Exceptions

The try...catch Statement

Unable to divide.

<?php
// this throws an exception and will result in a fatal error if it is not caught
function divide($dividend, $divisor) {
  if($divisor == 0) {
    throw new Exception("Division by zero");
  }
  return $dividend / $divisor;
}

// this catches the error and allows the script to continue and the page finishes loading
try {
  echo divide(5, 0);
} catch(Exception $e) {
  echo "Unable to divide.";
}
?>

The catch block indicates what type of exception should be caught and the name of the variable which can be used to access the exception. In the example above, the type of exception is Exception and the variable name is $e.
