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 */ error_reporting (7); // Old syntax, PHP 2/3 error_reporting (E_ERROR | E_WARNING | E_PARSE); // New syntax for PHP 3/4 /* Good to use for simple running errors */ error_reporting (15); // Old syntax, PHP 2/3 error_reporting (E_ERROR | E_WARNING | E_PARSE | E_NOTICE); // New syntax for PHP 3/4 /* good for code authoring to report uninitialized or (possibly mis-spelled) variables */ error_reporting (63); // Old syntax, PHP 2/3 error_reporting (E_ALL); // New syntax for PHP 3/4 /* report all PHP errors */ |
