error_reporting

(PHP 3, PHP 4 )

error_reporting -- set which PHP errors are reported

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
