An exception can be thrown, and caught ("catched") within PHP. Code may be surrounded in a try block, to facilitate the catching of potential exceptions. Each try must have at least one corresponding catch or finally block. The thrown object must be an instance of the Exception class or a subclass of Exception. Trying to throw an object that is not will result in a PHP Fatal Error. catch Multiple catch blocks can be used to catch different classes of exceptions. Normal execution (when no exception is thrown within the try block) will continue after that

These errors can be prevented to a very large degree by careful programming. External Errors: These are errors related to the interactions with the world outside your code (e.g., failing to opening a file or database, the network connection dropping, being unable to load a certain PHP module, etc.). These errors will always occur, but their impact can be mitigated. The better you prepare your code for these external errors, by assuming as little as possible when your code is executing, the
