CI is known for its compatibility and "Zero Configuration". CI 1.x is even fully compatible with php4.

CodeIgniter is fully compatible with the PHP5 Standard Edition.

Install php and its common extensions ...... =

You really don't need to configure anything. Write the code first as needed, and add more when necessary.

Basically, you don't need to install extensions. You just need to install php.
