Break large .csv into smaller .csvs with proper header field with PHP
<p>We have a little program we use internally to upload lists into our system. It won't take files longer then 5k lines, and needs each .csv to have the same formatting, including the header row from the original file.</p>

<p>Could someone point me in the direction of a script I could use to accomplish this on a server running PHP?</p>

<p>Thanks!</p>
