Escaping special characters
<p>Just a quick question. I want to send data from Javascript to a PHP script to store it in my database, then getting it back the same way (a script calls a PHP function, and data is sent back with JSON). </p>

<p>Which function should I use in the javascript ? I should never need to get the data only with PHP, so is it ok to use <code>escape(string);</code> then <code>unescape(encoded_string);</code> to display ?</p>

<p>Thanks.<br>

<p>EDIT : Forgot to mention : The data is a string from an user input (hence the security issues)</p>
