How to set the error level?
error_reporting(-1) displays all errors, error_reporting(0) masks all errors
. ini_set('error_reporting',0) also masks all errors.
Error_reporting can be set in the php.ini file to make the script display or not display certain errors. ini_set('display_errors','On') displays errors.
Note: error_reporting() sets what kind of errors are reported, and ini_set('display_errors','On') sets whether errors are output. Thus error_reporting(-1) and ini_set('display_errors',0) can be used to set the log: errors are reported and not output.
Example:
error_reporting(E_ALL&~E_NOTICE)不显示通知级别的错误。“~”表示非。
