Php Custom Error Handler Class
obvious. Users will continuously find ways to trigger errors within your application and how you record, contain, and eliminate these errors is a true testament to your code. http://www.w3schools.com/php/php_error.asp PHP provides means for trapping errors and dealing with them the way you need them to be dealt with. The best part of PHP error handling is that it's extremely customizable using PHP's set_error_handler() function. The Error Handler function xhandler($number,$string,$file,$line,$context) { //log to text file? //log to xml file? //store in database? //whatever you want to do! https://davidwalsh.name/custom-error-handling-php } The Explanation Your error handling function can accept five parameters: $number - Integer error number representative of the PHP error level $string - String description of the error $file - File in which the error occurred $line - Line number in the file that the error occurred $context - Context of the area, including an array of each variable in scope The Usage /* use this error for ALL (E_ALL) errors */ set_error_handler('xhandler',E_ALL); This is a basic example of the custom error handling in PHP. The programming and methods you use to save and analyze these errors is up to you, but common methods include: Saving the error to a database Saving the error information to a local file (text, xml, etc.) Redirecting the user to another page Absolutely nothing (I've actually seen this in other dev's code). Though you can do almost anything in your error handling function(s), I recommend the following for error handling functions: Store the date/time of the error Use more than o

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 error handling 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 php error handling 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 environmen
