Codeigniter Error Handling Example
up vote 0 down vote favorite 3 I'm fairly new to PHP and the setting of custom error handlers, but I have some code which works fine outside of CI but I can't work out how to integrate this into a CI Controller. I get an error "Message: Undefined property: Errors::$my_error_handler" My Controller is: An error ($number) occurred on line $line and in the file: $file.
$message
"; $email .= "" . print_r($vars, 1) . ""; $headers = 'Content-type: text/html; charset=iso-8859-1' . "\r\n"; // Email the error to someone... error_log($email, 1, 'name@domain.com', $headers); // Make sure that you decide how to respond to errors (on the user's side) // Either echo an error message, or kill the entire project. Up to you... // The code below ensures that we only "die" if the error was more than // just a NOTICE. if ( ($number !== E_NOTICE) && ($number < 2048) ) { die("There was an error. Please try again later."); } } function test() { // We should use our custom function to handle errors. set_error_handler($this->my_error_handler); // Trigger an error... (var doesn't exist) echo $somevarthatdoesnotexist; } } ?> If there is a better way to email error messages using CI please let me know. php codeigniter share|improve this question asked Jun 12 '12 at 11:51 Paul Benbow 1561620 does this help: stackoverflow.com/questions/6403571/… –DemoUser Jun 12 '12 at 11:57 add a comment| 3 Answers 3 active oldest votes up vote 7 down vote accepted I don't think that

Exception Handling In Codeigniter
in CodeIgniter SonalFebruary 9, 2015, 2 years ago008.5K Today we are going codeigniter try catch to understand the error handling especially in CI in this Error Handling in CodeIgniter tutorial. PHP has codeigniter log_message various levels of error reporting for different errors. What level of error we get when we run our script depends on our server configuration. The decision to show the error http://stackoverflow.com/questions/10996096/how-to-set-custom-error-handler-in-codeigniter-to-email-errors on screen or not, is controlled by the server setting called display_errors. The developer may or may not have access to the underlying server setting such as display_errors. So the underlying settings are unknown to us. These settings are made known to us by codeigniter by the use of error_reporting() function on every page call, which overrides the settings https://www.eduonix.com/blog/web-programming-tutorials/error-handling-codeigniter/ of display_errors. This error_reporting() is found in the main index.php file. Error functions in codeigniter are simple procedural interfaces that are available globally throughout the application, hence the error messages are triggered without caring about the class/function scope. CodeIgniter helps us to report errors into our applications by using the following functions: show_error(): This function displays the error message using the template in application/errors/error_general.php. Syntax of show_error() function is: PHP show_error(‘message’,status_code); 1 show_error(‘message’,status_code);
Here, the parameter message is mandatory and is the string error message to be shown. The parameter status_code is optional which is an integer value representing the HTTP status code to be sent with the error. Example: PHP show_error(‘File not found!’); 1 show_error(‘File not found!’); show_404(): This function displays the 404 error message supplied to it by the template in application/errors/error_404.php. Syntax of show_404() function is: PHP show_404(‘page’[,’log_error’]); 1 show_404(‘page’[,’log_error’]); The first parameter page in show_404() function is the path of the page that is not found. In general we can see that 404 messages are shown by codeigniter auLearn Bootstrap Learn Graphics Learn Icons Learn How To JavaScript Learn JavaScript Learn jQuery Learn jQueryMobile Learn AppML Learn AngularJS Learn JSON Learn AJAX Server Side Learn SQL Learn PHP Learn ASP Web Building Web Templates Web Statistics Web Certificates XML http://www.w3schools.com/php/func_error_set_error_handler.asp Learn XML Learn XSLT Learn XPath Learn XQuery × HTML HTML Tag Reference HTML Event Reference HTML Color Reference HTML Attribute Reference HTML Canvas Reference HTML SVG Reference Google Maps Reference CSS CSS Reference CSS Selector Reference W3.CSS http://programmers.stackexchange.com/questions/133335/handling-errors-in-php-when-using-mvc Reference Bootstrap Reference Icon Reference JavaScript JavaScript Reference HTML DOM Reference jQuery Reference jQuery Mobile Reference AngularJS Reference XML XML Reference XSLT Reference XML Schema Reference Charsets HTML Character Sets HTML ASCII HTML ANSI HTML Windows-1252 HTML ISO-8859-1 error handling HTML Symbols HTML UTF-8 Server Side PHP Reference SQL Reference ASP Reference × HTML/CSS HTML Examples CSS Examples W3.CSS Examples Bootstrap Examples JavaScript JavaScript Examples HTML DOM Examples jQuery Examples jQuery Mobile Examples AngularJS Examples AJAX Examples XML XML Examples XSL Examples XSLT Examples XPath Examples XML Schema Examples SVG Examples Server Side PHP Examples ASP Examples Quizzes HTML Quiz CSS Quiz JavaScript Quiz Bootstrap Quiz jQuery Quiz PHP Quiz SQL Quiz XML Quiz × handling in codeigniter PHP Tutorial PHP HOME PHP Intro PHP Install PHP Syntax PHP Variables PHP Echo / Print PHP Data Types PHP Strings PHP Constants PHP Operators PHP If...Else...Elseif PHP Switch PHP While Loops PHP For Loops PHP Functions PHP Arrays PHP Sorting Arrays PHP Superglobals PHP Forms PHP Form Handling PHP Form Validation PHP Form Required PHP Form URL/E-mail PHP Form Complete PHP Advanced PHP Arrays Multi PHP Date and Time PHP Include PHP File Handling PHP File Open/Read PHP File Create/Write PHP File Upload PHP Cookies PHP Sessions PHP Filters PHP Filters Advanced PHP Error Handling PHP Exception MySQL Database MySQL Database MySQL Connect MySQL Create DB MySQL Create Table MySQL Insert Data MySQL Get Last ID MySQL Insert Multiple MySQL Prepared MySQL Select Data MySQL Delete Data MySQL Update Data MySQL Limit Data PHP - XML PHP XML Parsers PHP SimpleXML Parser PHP SimpleXML - Get PHP XML Expat PHP XML DOM PHP - AJAX AJAX Intro AJAX PHP AJAX Database AJAX XML AJAX Live Search AJAX RSS Reader AJAX Poll PHP Examples PHP Examples PHP Quiz PHP Certificate PHP Reference PHP Array PHP Calendar PHP Date PHP Directory PHP Error PHP Filesystem PHP Filter PHP FTP PHP HTTP PHP Libxml PHP Mail PHP Math PHP Misc PHP MySQLi PHP SimpleXML PHP String PHP XML PHP Zip PHP Timezones PHP set_error_handler() Function PHP Erro

I've never been good at handling errors without it getting messy. My main concern is when returning errors to the user. Is it good practice to use exceptions and throw/catch exceptions rather than returning 0 or 1 from functions and then using if/else to handle the errors. Thus, making it easier to inform the user about the issue. I tend to go away from exceptions. My Java tutor at university some years ago told me "exceptions shouldn't be used in production code it's more for debugging". I get the feeling he was lying. But, an example, I have code that adds a user to a database. During the process more than 1 thing could go wrong, such as a database issue, a duplicate entry, a server issue, etc. When an issue happens during registration the user needs to know about it. What's the best way to handle errors in PHP, keeping in mind that I'm using an MVC framework. php mvc error-handling share|improve this question edited Feb 4 '12 at 21:15 Thomas Owens♦ 46.9k12117200 asked Feb 4 '12 at 20:38 James Jeffery 16113 add a comment| 3 Answers 3 active oldest votes up vote 13 down vote Is it good practice to use exceptions and throw/catch exceptions rather than returning 0 or 1 from functions and then using if/else to handle the errors. Thus, making it easier to inform the user about the issue. Yes, yes, yes! If you want to have clean code, you should almost exclusively use exceptions and don't bother using error codes. Error codes are meaningless. They are almost always tied to some numerical constant that does not reveil much information. It can make your code unreadable and they'll make it hard to propagate data alongside the error. Exceptions, however, are classes and can contain a
