Script to open folders and files

Hi guys,
I am just writing some code that will go through an entire folder (all sub-folders and files in it) and will open each file and search it for a search phrase. Basically, I have around 7 folders inside one folder and all these folders have txt files and I want to create a programme that will open all these files and search for the phrase. I can do everything BUT ....

I just need to know if there is a command that:
1. Gives me a list of all folders in a folder
2. Gives me a list of all files in a folder

I don't need all the code, I can manage the rest once I get these commands.

try opendir() and readdir() and is_dir();
Some good examples at php.net and search for opendir

 

Thanks for that. I'll try it out over the weekend and see if it works.
