error_reporting
(PHP 3, PHP 4)
Description
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.
error_reporting() sets PHP's error reporting level, and returns the old level. The level parameter 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.
Some example uses:
瞰赽 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);?
The available error level constants are listed below. The actual meanings of these error levels are described in the predefined constants.
