PHP Functions
Function: error_reporting (PHP 3, PHP 4, PHP 5) error_reporting -- Sets which PHP errors are reportedDescriptionint error_reporting ( [int level] )The error_reporting() function sets the error_reporting directive at runtime. PHP has many levels of errors, using this function sets that level for the duration (runtime) of your script. Parameters
level The new error_reporting level. It takes on either a bitmask, or named constants. Using named constants is strongly encouraged to ensure compatibility for future versions. As error levels are added, the range of integers increases, so older integer-based error levels will not always behave as expected. The available error level constants are listed below. The actual meanings of these error levels are described in the predefined constants . Table 1. error_reporting() level constants and bit values value constant 1 E_ERROR 2 E_WARNING 4 E_PARSE 8 E_NOTICE 16 E_CORE_ERROR 32 E_CORE_WARNING 64 E_COMPILE_ERROR 128 E_COMPILE_WARNING 256 E_USER_ERROR 512 E_USER_WARNING 1024 E_USER_NOTICE 2047 E_ALL 2048 E_STRICTReturn ValuesReturns the old error_reporting level. Examples
Example 1. error_reporting() examples <?php // Turn off all error reporting error_reporting(0); // Report simple running errors error_reporting(E_ERROR | E_WARNING | E_PARSE); // Reporting E_NOTICE can be good too (to report uninitialized // variables or catch variable name misspellings ...) error_reporting(E_ERROR | E_WARNING | E_PARSE | E_NOTICE); // Report all errors except E_NOTICE // This is the default value set in php.ini error_reporting(E_ALL ^ E_NOTICE); // Report all PHP errors (bitwise 63 may be used in PHP 3) error_reporting(E_ALL); // Same as error_reporting(E_ALL); ini_set('error_reporting', E_ALL); ?> NotesWarning With PHP > 5.0.0 E_STRICT with value 2048 is available. E_ALL does NOT include error level E_STRICT . Most of E_STRICT errors are evaluated at the compile time thus such errors are not reported in the file where error_reporting is enhanced to include E_STRICT errors. Related Function(s) |
