Difference Between Error Handling And Exception Handling In Php
missing it somewhere in the PHP manual, but what exactly is the difference between an error and an exception? The only difference that I can see is that errors and exceptions are handled differently.

Error Exception Java
vote 65 down vote accepted Exceptions are thrown - they are intended to be caught. Errors are generally unrecoverable. Lets say for instance - you have a block of code that will insert a row into a database. It is possible that this call fails (duplicate ID) - you will want to have a "Error" which in this case is an "Exception". When you are inserting these rows, you can do something like this try { $row->insert(); $inserted = true; } catch (Exception $e) { echo "There was an error inserting the row - ".$e->getMessage(); $inserted = false; } echo "Some more stuff"; Program execution will continue - because you 'caught' the exception. An exception will be treated as an error unless it is caught. It will allow you to continue program execution after it fails as well. share|improve this answer answered May 8 '09 at 19:58 gnarf 73.5k1497149 14 Errors are generally unrecoverable <-- actually, this isn't really true. E_ERROR and E_PARSE are the two most common unrecoverable errors (there are a couple of others) but the vast majority of errors you'll see in dev are recoverable (E_NOTICE, E_WARNING et al). Unfortunately PHP's error handling is a complete mess - all kinds of things trigger errors

This depends on your needs. It can't be said which one is better (and there are other ways of error handling as well you should put into consideration when you actually want to discuss error handling which this site is probably not the right place for). Any benefit's throwing an exception instead of stoping executing script ? An exception can be caught, a die can't be caught. If you want to test your code for example, dies are often a show-stopper. Next to that an exception can carry more information and carry it more precisely. The message for example is more accessible with an exception than it is with a die. An exception keeps the file and line where it was thrown. For debugging there are stack traces and so
