ERROR TYPE Parse error: A problem with the syntax of your program, such as leaving a semicolon off of the end of a statement. The interpreter stops running your program when it encounters a parse error. Fatal error: A severe problem with the content of your program, such as calling a function that hasn't been defined. The interpreter stops running your program when it encounters a fatal error. Warning: An advisory from the interpreter that something is fishy (เหม็นคาว) in your program, but the interpreter can keep going. Using the wrong number of arguments when you call a function causes a warning. Notice: A tip from the PHP interpreter, playing the role of Miss Manners. For example, printing a variable without first initializing it to some value generates a notice. Reference : http://onlamp.com/pub/a/php/2004/08/12/DebuggingPHP.html
