Errors and Logging Value Constant Description Note 1 E_ERROR (integer) Fatal run-time errors. These indicate errors that can not be recovered from, such as a memory allocation problem. Execution of the script is halted. 2 E_WARNING (integer) Run-time warnings (non-fatal errors). Execution of the script is not halted. 4 E_PARSE (integer) Compile-time parse errors.

The result is an integer like the one you see so if you set it to E_ALL & ~E_NOTICE it will
is run based on this setting of the php.ini file the generated errors and/or warnings will be shown or not. Generally speaking in a development environment it is recommended to set this as high as possible http://www.efrag.gr/2013/01/how-to-get-your-error-reporting-constant-values/ so that you are informed about all the little details of your code whereas inĀ a production environment this setting is usually set to something less "explanatory". In order to set the value of the error_reporting http://www.hacksparrow.com/turning-on-php-error-reporting-php-error_reporting.html directive php constant values and bitwise operators are used, as they are described in the PHP manual . The setting can be set during runtime using the php error_reporting() function (manual) passing as a parameter php error the int value calculated based on the constant values and bitwise operators used. The function returns the integer value of the previous error_reporting level. Now if you wish to find out what is your current error_reporting level you could go and have a look in your php.ini file or you could use the error_reporting() function with no parameters, in which case the function will return an integer value representing the current error php error reporting reporting level. If you go via the php.ini file you will see the names of the constants used and the operations applied to produce your current reporting level but if you try to get a similar result via a php file that you have written you might notice that it is more difficult to understandĀ what is going on since now you are only dealing with an integer value and not with the named constants. So which is the description of your error reporting level and how can you retrieve it from within a php file? In order to be able to retrieve the error reporting level we will create a class named ErrorReporting with two protected properties $level and $levels which will hold the current integer value of the error reporting level that we have in our system and the second will be an array of the php constants along with their integer value. When a new object is constructed the current integer value of the error reporting level is stored in the $level variable. In addition we will need a public function that will return the error reporting level as a string representation of the constants. For this function to return a result we should first find out which bits are t
error How do you turn on error reporting in PHP?PHP error_reporting has a changeable value of 'PHP_INI_ALL', which means you can set the value anywhere in the system. To turn on PHP Error Reporting in your PHP file add this at the top of the file:ini_set('display_errors', 1);error_reporting(E_ALL | E_STRICT);The same can be achieved using the .htaccess file. To turn on PHP Error Reporting using .htaccess file add this in your .htaccess file:php_flag display_errors onphp_value error_reporting 8191The integer value of 8191 is the same as 'E_ALL|E_STRICT'. Although integer values and error constants both work for setting the error reporting level, it is highly recommended to use PHP predefined error constants, because integer values may change in future versions of PHP but constants will always point to the intended integer value.Tip: to get the correspondig integer value of error reporting flag, just echo the PHP error predefined constant parameters their combinations.echo error_reporting(E_ALL | E_STRICT); // 8191echo error_reporting(E_NOTICE); // 8echo error_reporting(E_PARSE); // 2echo error_reporting(E_WARNING); // 2echo error_reporting(E_ERROR); // 1echo error_reporting(E_ERROR | E_PARSE); // 5The above tip works because the PHP error reporting constants are mapped to real integers. So it's no surprise you can see integer values when you echo them or their bitwise operations.ReferencesPHP ini_setPHP error_reportingPHP Predefined Error ConstantsPHP Constants Related to this post Kohana Route not Working: Kohana gives a 404 Error for Route PHP CURLOPT_GET Does not Exist!
