Sql file extension type
<p><strong>What is the sql extension type?</strong> <br>
I want to upload to some folder in my server only .sql files.<br> 
I know that for txt is text/plain. what is for sql files?<br></p>

<pre><code> if($_FILES['userfile']['type'] != 'THE SQL EXTENSION'){
    echo ' File is not an sql file.';
    exit;
}
</code></pre>

<p>thanks.</p>
