This function can be used for defining your own way of handling errors during runtime, for example in applications in which you need to do cleanup of data/files when a critical error happens, or when you need to trigger an error under certain conditions (using trigger_error()). It is important to remember that the standard PHP error handler is completely bypassed for the error types specified by error_types unless the callback f

Php Error Handling Best Practices
2011 Errors are the most common event a developer faces when programming. Errors can be php fatal error handler categorized as syntactical, run-time, or logical: missing the semicolon at the end of a statement is an example of a syntax error; trying error handler codeigniter 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 http://php.net/manual/en/function.set-error-handler.php 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 https://www.sitepoint.com/error-handling-in-php/ 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 be set either in php.ini, in a web server configuration file (httpd.conf or .htaccess file), or at run-time in your script using the ini_set() function. Read the documentation for more information on the directives and how/where to set them. Creating Custom Error Handlers It's also good practice not to display raw errors to the end user. Errors that are displayed should be abstracted with friendly, custom error messages. PHP not only provides built-in functions for logging and displaying errors, but also for raising them. You can pragmatically trigger an error of a specific level using trigger_error(). For example, this code triggers an

Saiful Islam 88441626 add a comment| 6 Answers 6 active oldest votes up vote 23 down vote accepted Simple Answer: You can't. See the manual: The following error types cannot be handled with a user defined function: php error handling E_ERROR, E_PARSE, E_CORE_ERROR, E_CORE_WARNING, E_COMPILE_ERROR, E_COMPILE_WARNING, and most of E_STRICT raised in the file where set_error_handler() is called. For every other error, you can use set_error_handler() EDIT: Since it seems, that there are some discussions on this topic, with regards to using register_shutdown_function, we should take a look at the definition of handling: To me, handling an error means catching the error and reacting in a way that is "nice" for the user and the underlying data (databases, files, web services, etc.). Using register_shutdown_function you cannot handle an error from within the code where it was called, meaning the code would still stop working at the point where the error occurs. You can, however, present the user with an error message instead of a white page, but you cannot, for example, roll back anything that your code did prior to failing. share|improve this answer edited Sep 30 '11 at 20:58 answered Dec 14 '09 at 10:59 Dan Soap 7,38711943 3 Actually you can handle those errors with an user defined function. All you have to do is define register_shutdown_function. See my answer below for a working example I implemented in my website. –jdias Sep 20 '11 at 18:32 Yes, you can. However, ther
