quoted_printable_decode
Took me a while to realize this was NOT the command I wanted for escaping potentially harmful characters in a string that would be used as part of a system command. Instead, I needed either escapeshellarg() (http://www.php.net/manual/en/function.escapeshellarg.php) or escapeshellcmd() (http://www.php.net/manual/en/function.escapeshellcmd.php)

This function escapes characters that have special meaning in regular expressions. preg_quote() <http://php.net/manual/en/function.preg-quote.php> has similar functionality, but is more powerful since it escapes more characters (including one user-specified character).

qutemeta() is note for quoting meta tags, but is for quoting characters which can be misunderstanded by php or a database.
