$end of line

Global pattern flags

m modifier: multiline. Causes ^ and $ to match the start and end of each line, not only the start and end of the string

g modifier: global. Finds all matches instead of stopping after the first

x modifier: extended. Ignores unescaped whitespace and comments outside character classes

u modifier: unicode. Treats the pattern and subject as UTF-16

X modifier: eXtra. A \ followed by a letter with no special meaning causes an error
