This example will log the errors to syslog instead of displaying them in the browser. ini_set("display_errors", 0); ini_set("log_errors", 1); //Define where do you want the log to go, syslog or a file of your liking with ini_set("error_log", "syslog"); share|improve this answer edited Dec 1 '08 at 21:12 answered Dec 1 '08 at 21:02 Vinko Vrsalovic 166k35272324 As a heads up in replacement of "syslog" you can place a file path and write the log to whatever location you require. –Ryan Rentfro Dec 1 '15 at 21:05 add a comment| up vote 4 down vote Assuming you are in control of the php.ini file, you can make these changes globally inside that file instead of having the ini_set code laying around in all your php files (which you might forget to put in one of your files one day, which could be bad in production). share|improve this answer answered Dec 1 '08 at 22:32 grepsedawk 4,38741618 add a comment| up vote 2 down vote set an environment variable on your development machine. then you can check your environment in the beginning of your code to make sure you are on the development en

Join them; it only takes a minute: Sign up Turn off or handle errors within a production environment? up vote 1 down vote favorite 2 After having an argument with my team because we all have different views on this sort of situation.. When is it actually acceptable to turn off PHP error messages, or php error reporting to suppress some functions which are throwing warnings, notices for whatever reason.. I understand everyone says that you should turn off error_reporting within a production environment, but that might cause some complications which will not be picked up.. So nothing will get fixed, furthermore. PHP comes with many different methods to control error messages.. For example: $Var = "Variable Is Set"; if (@$Var){ echo $Var; } Over: if (isset($Var)){ echo $Var; } Because we have a set variable, this will sucessfully echo.. Whereas if we didn't have a set variable, this would throw a notice.. So Which one to use? The isset or error suppression? And within a production environment, which one would be more acceptable to use? error_reporting(0); The above will turn off all types of PHP error reporting, giving no error messages even if something is encountered. So in some cases this could lead to broken code that stops working for an unknown reason, due to the message being destroyed or: set_error_handler(""); The above enables a custom err
Error Settings Error settings in php.ini tell PHP interpreter what kind of errors should be reported and where those should be reported. You may enable these settings in your development environment and disable few in your production environment since useful information error reports provide can also be sensitive information that outsiders shouldn't see. display_errors Default value of this setting is ‘On'. It tells PHP interpreter that if it finds a type of error mentioned in error_reporting setting then add it to the output of the script. This basically means to show the errors in web browser. display_startup_errors Default value of this setting is ‘Off'. This tells whether to display errors that occur in PHP's startup sequence. PHP manual recommends turning this ‘On' only in your development environment as an aid for debugging. log_errors Default value of this setting is ‘Off'. This setting tells whether errors should be logged in web server's error log file. When you finish your application and put it live, it's a good practice that you turn ‘Off' display_errors and turn ‘On' log_errors in your production server's php.ini file. This prevents users seeing any sensitive information that can go with error reports and let you still see them via web server's error log. But in development, you would rather like to see errors on the web browser and would set the settings other way around. error_reporting This setting tells what type of errors should be displayed and/or logged. There are constants that can be given as values to this setting and there is single constant (E_ALL) that represents all error types. Default value of this setting will be like below. error_reporting = E_ALL & ~E_NOTICE Above it instructs to discard errors fall into notices category. For an example, if you used an undefined variable in an echo() statement, PHP generates a notice. This can be a useful feature in debugging. Think that you defined a variable as $name but mistyped it in the echo() statement as $nmae then PHP interpreter would let you know it. So, make sure you enable notices in your development environment by using just E_ALL as below. error_reporting = E_ALL E_STRICT was introduced in PHP 5.0.0 and till PHP 5.4.0, it was not included in E_ALL. So, if you are using a version in-between, have the error_reporting setting as below in your development
