Hello everyone,
I've read, in the manual of PHP, about this function, i.e. quotemeta(string $str).
This function
Returns a version of str with a backslash character (\) before every character that is among these:
. \ + * ? [ ^ ] ( $ )
Now, I understand what it says, but I don't understand two things. First, where could this function be useful? And second, what are meta characters in PHP?
Thank you.
