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 last catch block defined in sequence. Exceptions can be thrown (or re-thrown)

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 an

Errors can be categorized as syntactical, run-time, or logical: missing the semicolon at the end of a statement is an example of a syntax error; trying to connect to a database when the server is down is an example of a run-time error; providing incorrect data to a variable is an example of a logic error. To help reduce the number of errors in your code, and to mitigate their effects, proper error handling is essential in your web application. This article is a crash course in PHP error handling. You'll learn about PHP's built-in error reporting levels, and how to handle errors with custom error handlers and exception handling. PHP Error Reporting Levels All errors and warnings should be logged. Based on the severity of an error, notifications should be sent out to other systems/teams. So that you can better gauge its severity, PHP provides several built-in error levels to describe the nature of an error. Each level is represented by an integer value and named constant which can be used by the programmer. The table below is taken from the official PHP documentation and shows some of the different levels. The levels can be masked together with bit-operators to include or subtract them from PHP's configuration. For example, E_ALL|E_STRICT enables all errors and warnings with the addition of E_STRICT (necessary in versions of PHP prior to 5.4). PHP provides a few configuration directives related to logging and displaying errors. Their values are generally different depending on whether the system is in a development or a production environment. This table shows some of the error-related directives. The configuration directives can
