syslog.filter

INI • Added in PHP 7.3

syslog.filter — Set this to disable filtering control characters (the default). Some loggers only accept NVT-ASCII, others accept anything that's not control characters. If your logger accepts everything, then no filtering is needed at all. Allowed values are: ascii (all printable ASCII characters and NL) no-ctrl (all characters except control characters) all (all characters) raw (like "all", but messages are not split at newlines)

Default value "no-ctrl"
Development value "no-ctrl"
Production value "no-ctrl"

Modifiability: INI_ALL - The syslog.filter INI directive can be configured anywhere, including php.ini files, ini_set calls, Apache .htaccess files, per-directory .ini files, etc.
