php的error_reporting设置

// 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);

// 报除E_NOTICE之外的所有错误
// php.ini中的默认设置
error_reporting(E_ALL ^ E_NOTICE);

// 报所有错(see changelog)
error_reporting(E_ALL);

// 报所有错
error_reporting(-1);

//同 error_reporting(E_ALL);
ini_set(‘error_reporting‘, E_ALL);
