What am I misunderstanding about quotemeta function?
You usually would use quotemeta on data coming from the database, or the
user, or externally, or, errr, basically things you haven't typed in to
PHP, that you need to pass into Regular Expressions.
In those cases, you've already got the $ (and other characters)
successfully embedded in the string, but you want to escape them for
whatever reason.
A better example code would be:
$string =
'period.backslash\\plus+star*question?lbracket[rbracket]carat^lparen(rparen)dollar$';
echo "<PRE>", quotemeta($string), "</PRE>";
Interesting aside... with the test string above, I noticed that
backslash\\ only resolved to two backslashes. I thought there would be
thats correct...
echo "\\"; // shows one backslash
4. It seems that quotemeta will resolve \ and \\ to \\, \\\ and \\\\
resolve to \\\\, etc.
