PHP 忒聊 綴豖 ヶ輛 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. 桶跡 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 See also the display_errors directive and ini_set(). 綴豖 れ萸 ヶ輛 error_log 奻珨撰 restore_error_handler
