=== Flags ===
Flags are used to redefine the behaviour of a regular expression. These flags include:
{| class="wikitable"
|+Flags
!Flag
!Name
!Description
|-
|g
|Global
|Finds all the matching sub-strings not only the first one
|-
|i
|Case-insensitive
|Makes the rule case-insensitive. For example if the rule is [e] and the flag [ig] all e '''and''' E's get matched
|-
|m
|multi-line
|Changes the meaning of the rule $ and ^ to be the end and beginning of a line and whole string
|-
|s
|dotalls
|changes the . character to include '''every''' character including new-line
|}
To use multiple flags you write them, as seen in the description of the case-insensitive flag, after another with '''no delimiter''' (a space or comma inbetween the flags). Order does not matter.
