; This directive controls whether or not and where PHP will output errors,\r\n; notices and warnings too. Error output is very useful during development, but\r\n; it could be very dangerous in production environments. Depending on the code\r\n; which is triggering the error, sensitive information could potentially leak\r\n; out of your application such as database usernames and passwords or worse.\r\n; For production environments, we recommend logging errors rather than\r\n; sending them to STDOUT.\r\n; Possible Values:\r\n; Off = Do not display any errors\r\n; stderr = Display errors to STDERR (affects only CGI\/CLI binaries!)\r\n; On or stdout = Display errors to STDOUT\r\n; Default Value: On\r\n; Development Value: On\r\n; Production Value: Off\r\n; http:\/\/php.net\/display-errors\r\ndisplay_errors = Off\r\n<\/pre>\n","protected":false},"excerpt":{"rendered":"
