modes

/i makes the regex match case insensitive.
/s enables "single-line mode". In this mode, the dot matches newlines.
/m enables "multi-line mode". In this mode, the caret and dollar match before and after newlines in the subject string.
/x enables "free-spacing mode". In this mode, whitespace between regex tokens is ignored, and an unescaped # starts a comment.
