Including remove files in php

http://php.net/manual/en/features.remote-files.php

http://stackoverflow.com/questions/1158348/including-a-remote-file-in-php

To allow inclusion of remote files, the directive allow_url_include must be set to On in php.ini
But it is bad, in a security-oriented point of view ; and, so, it is generally disabled (I've never seen it enabled, actually)
It is not the same as allow_url_fopen, which deals with opening (and not including) remote files -- and this one is generally enabled, because it makes fetching of data through HTTP much easier (easier than using curl)

To use remote includes, the allow_url_fopen and allow_url_include option must be set in php.ini
Be aware that if the remote server is php-enabled, you'll get the output of that remote script, not the script itself. If you do want to fetch the source, you could add a symlink on the remote server, e.g. ln -s file.php file.php.source and then make your include reference file.php.source instead.

What are advantages and disadvantages of PHP / Limitation of PHP

Advantages of PHP

Open source: It is developed and maintained by a large group of PHP developers, this will helps in creating a support community, abundant extension library.
Speed: It is relative fast since it uses much system resource.
Easy to use: It uses C like syntax, so for those who are familiar with C, it’s very easy for them to pick up and it is very easy to create website scripts.
Stable: Since it is maintained by many developers, so when bugs are found, it can be quickly fixed.
Powerful library support: You can easily find functional modules you need such as PDF, Graph etc.
Built-in database connection modules: You can connect to database easily using PHP, since many websites are data/content driven, so we will use database frequently, this will largely reduce the development time of web apps.
Can be run on many platforms, including Windows, Linux and Mac, it’s easy for users to find hosting service providers.

Disadvantages of PHP

Security : Since it is open sourced, so all people can see the source code, if there are bugs in the source code, it can be used by people to explore the weakness of PHP
Not suitable for large applications: Hard to maintain since it is not very modular.
Weak type: Implicit conversion may surprise unwary programmers and lead to unexpected bugs. For example, the strings “1000” and “1e3” compare equal because they are implicitly cast to floating point numbers.
