I have a directory of pictures that I want to loop through and do some file calculations on. It might just be lack of sleep, but how would I use PHP to look in a given directory, and loop through each file using some sort of for loop? Check out the DirectoryIterator class. The recursive version is RecursiveDirectoryIterator. Looks for the function glob :. Use the glob function in a foreach loop to do whatever is an option.

Would you like to view your directories in your browser this script might come in handy.
If I called the function more than once on the same page it would combine the file lists. I looked at Lasse Dalegaard's example and used the following solution. I ran into a little snag in example 1. I was trying to print the files numerically in a directory.
Solution: Use scandir instead php5 or store the files in an array and sort it. Hope this helps someone. I was trying to access network drives using this opendir function.
I read so many posts saying that it was almost impossible to access a network drive and finally, I found the answer; there are 2 steps to be followed to access a network drive with PHP either on the same machine or another machine.

Unless you specify no sorting, file names are sorted in ASCII alphabetic order, meaning numbers first, then uppercase, then lowercase letters, even on operating systems whose file system ignores the case of file names when it does its own sorting. For example, on Mac OS, the following files will appear in this order in the Finder, when your disk is formated using the standard file system: 1file. I wrote this function to read a folder and place all the folders and sub folders it contains into an array.
Back in the saddle of scandir I wrote this function for a function that I needed to seperate directories from files. Since I am still learning from my last example way below I would figure I would add it so it can be criticized. Here is such a function. By default, this function will keep in memory the scandir result, to avoid scaning multiple time for the same directory. Requires at least PHP5. Since scandir returns and array, here is a more concise method of dealing with the '.
