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

If you would handle errors properly then it may lead to many unforeseen consequences. Its very simple in PHP to handle an errors. Using die() function While writing your PHP program you should check all possible error condition before going ahead and take appropriate action when required. Try following example without having /tmp/test.xt file and with this file. This way you can write an efficient code. Using above technique you can stop your program whenever it errors out and display more meaningful and user friendly message. Defining Custom Error Handling Function You can write your own function to handling any error. PHP provides you a framework to define error handling function. This function must be able to handle a minimum of two parameters (error level and error message) but can accept up to five parameters (optionally: file, line-number, and the error context) − Syntax error_function(error_level,error_message, error_file,error_line,error_co
