Description
int
error_reporting ( [int level])
Sets PHP's error reporting level and returns the old level. The
error reporting level is either a bitmask, or named constant. 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.
Example 1. Error Integer changes error_reporting (55); // PHP 3 equivalent to E_ALL ^ E_NOTICE
/* ...in PHP 4, '55' would mean (E_ERROR | E_WARNING | E_PARSE |
E_CORE_ERROR | E_CORE_WARNING) */
error_reporting (2039); // PHP 4 equivalent to E_ALL ^ E_NOTICE
error_reporting (E_ALL ^ E_NOTICE); // The same in both PHP 3 and 4 |

Example 2. error_reporting() examples error_reporting(0);
/* Turn off all reporting */
/* Examples are presented firdt in the old sxtax (for PHP 2/3)
* and the new - and adviced - syntax for PHP 3/4
*/
error_reporting (7);
error_reporting (E_ERROR | E_WARNING | E_PARSE);
/* Good to use for simple running errors */
error_reporting (15);
error_reporting (E_ERROR | E_WARNING | E_PARSE | E_NOTICE);
/* good for code authoring to report uninitialized or (possibly mis-spelled) variables */
error_reporting (63);
error_reporting (E_ALL);
/* report all PHP errors */ |
