PHP is an open-source, server-side scripting language used primarily for web development on Apache and the usual programming language in a LAMP environment. You can learn PHP programming with the content, tutorials and PHP help and tutorial examples from Dev Shed. The PHP language lets programmers create web pages with dynamic content that can interact with databases and provides an object-oriented structure via php5 for developers. This makes it very popular for developing any web based software applications. If you’re looking for PHP answers, look no further. You have it right here and in our PHP forums.

How to Split a File During an FTP Upload Using PHP

Codex-M 26915

One of the known limitations of free hosting packages is the file upload limit. For example, some hosting companies set an upload limit of 500 KB. This means that for any uploads to the FTP server, the file should not be more than 500 KB or else the server won’t accept it and you will not be able to upload your file. Fortunately, by splitting your files, you can get around this limitation; this two-part tutorial series will show you how.
