error messages;

PHP error messages can vary

Notice	This is normally a simple message that reminds users of an oversight this could be the simple use of a variable that has not been declared
Strict notice	This is advice from the interpreter that could refer to "deprecated" code, this is code that is not supported as it could be out of date.
Warning	An error in the code somewhere that could be happening, however, it is not enough for the interpreter to stop running the PHP scripts.
Parse error	This refers to a syntax error or issue that has stopped the interpreter from running the code and outputting the results, this could be a missing semicolon.
Fatal error	This is a major problem with the code forcing it to stop from running.
