Best file type to store a single value in, for multiple access:
<p>I need to take a value from a database and store it in a file on the server, which can be accessed by multiple files, and users.</p>

<p>The data will always be a 2 digit integer value.</p>

<p>My thoughts are .txt, .ini, .xml but I am from far an expert on this, which file type would provide speed, reliability and be easy to dynamically update in php.</p>
