<div>
I suggest you split the file according to number of charachters instead number of lines.<br />
Cause one line could be longer than another.<br />
<br />
use file_get_contents() to get the file into a string. and the use strlen() to get char count.<br />
after that you write file back into several files with max char count of n.<br />
<br />
This way you can control exact file size to upload.

PHP is a widely-used server-side scripting language especially suited for web development, powering tens of millions of sites from Facebook to personal WordPress blogs. PHP is often paired with the MySQL relational database, but includes support for most other mainstream databases. By utilizing different Server APIs, PHP can work on many different web servers as a server-side scripting language.
