note 109890 added to errorfunc.constants

As an alternative to the examples provided by vladvarna and russthom, the following will display all error types currently reported by error_reporting. While it's just a personal preference, I find if/then constructs much more intuitive and easier to read than case/switch's. (Side note: The contants themselves could also be used for the "if" comparison, of course, instead of 1, 2, 4, etc... However, this way self-documents the value of each constant.) <?php //Just for example: error_reporting(E_ALL | E_STRICT); ini_set('display_errors', 'on'); function Show_Error_Types() { $E_level = error_reporting(); $E_types = ''; $spc = '<br>'; // Spacing: '<br>', or PHP_EOL, or whatever... if ( $E_level & 1 ) { $E_types .= 'E_ERROR' .$spc; } if ( $E_level & 2 ) { $E_types .= 'E_WARNING' .$spc; } if ( $E_level & 4 ) { $E_types .= 'E_PARSE' .$spc; } if ( $E_level & 8 ) { $E_types .= 'E_NOTICE' .$spc; } if ( $E_level & 16 ) { $E_types .= 'E_CORE_ERROR' .$spc; } if ( $E_level & 32 ) { $E_types .= 'E_CORE_WARNING' .$spc; } if ( $E_level & 64 ) { $E_types .= 'E_COMPILE_ERROR' .$spc; } if ( $E_level & 128 ) { $E_types .= 'E_COMPILE_WARNING' .$spc; } if ( $E_level & 256 ) { $E_types .= 'E_USER_ERROR' .$spc; } if ( $E_level & 512 ) { $E_types .= 'E_USER_WARNING' .$spc; } if ( $E_level & 1024 ) { $E_types .= 'E_USER_NOTICE' .$spc; } if ( $E_level & 2048 ) { $E_types .= 'E_STRICT' .$spc; } if ( $E_level & 4096 ) { $E_types .= 'E_RECOVERABLE_ERROR'.$spc; } if ( $E_level & 8192 ) { $E_types .= 'E_DEPRECATED' .$spc; } if ( $E_level & 16384 ) { $E_types .= 'E_USER_DEPRECATED' .$spc; } echo $spc.'error_reporting() is set to: '.$E_level.$spc.$E_types; } Show_Error_Types(); ?> ---- Server IP: 69.147.83.197 Probable Submitter: 71.99.64.218 ---- Manual Page -- http://www.php.net/manual/en/errorfunc.constants.php Edit -- https://master.php.net/note/edit/109890 Del: integrated -- https://master.php.net/note/delete/109890/integrated Del: useless -- https://master.php.net/note/delete/109890/useless Del: bad code -- https://master.php.net/note/delete/109890/bad+code Del: spam -- https://master.php.net/note/delete/109890/spam Del: non-english -- https://master.php.net/note/delete/109890/non-english Del: in docs -- https://master.php.net/note/delete/109890/in+docs Del: other reasons-- https://master.php.net/note/delete/109890 Reject -- https://master.php.net/note/reject/109890 Search -- https://master.php.net/manage/user-notes.php
