Disable PHP error reports

 
Int error_reporting (int [level]);

0: Disable the error report.

E_NOTICE indicates that the file is generally not recorded and used only when the program has an error, for example, an attempt to access a variable that does not exist or call stat () to view a file that does not exist.
E_WARNING is usually displayed, but the program execution will not be interrupted. This is effective for debugging. For example, call ereg () in a problematic General notation ().
E_ERROR is usually displayed and the program execution is interrupted. This mask cannot be used to trace memory configurations or other errors.
E_PARSE parses errors from the syntax.
E_CORE_ERROR is similar to E_ERROR, but does not include errors caused by the PHP core.
E_CORE_WARNING is similar to E_WARNING, but does not include PHP core error warnings.
