meaning of `$/i` in regular expressions
php, regex
Solution
`/` denotes the end of the pattern. The `i` is a modifier that makes the pattern case-insensitive, and the `$` anchor matches the end of the string.
Problem
What does the `$/i` mean in the following php code? ``` preg_match ('/^[A-Z \'.-]{2,20}$/i') ```
