- Check STDIN instead of local files and directories
-n Do not print warnings (shortcut for --warning-severity=0)
-w Print both warnings and errors (this is the default)
-l Local directory only, no recursion
-s Show sniff codes in all reports
-a Run interactively
-e Explain a standard by showing the sniffs it includes
-p Show progress of the run
-q Quiet mode; disables progress and verbose output
-m Stop error messages from being recorded
(saves a lot of memory, but stops many reports from being used)
-v Print processed files
-vv Print ruleset and token output
-vvv Print sniff processing information
-i Show a list of installed coding standards
-d Set the [key] php.ini value to [value] or [true] if value is omitted
--help Print this help message
--version Print version information
--colors Use colors in output
--no-colors Do not use colors in output (this is the default)
--cache Cache results between runs
