automatically searching for a file through a directory structure

[JimmyG]

Hi,
I have a directory structure which is populated with various files. Among these files are various test.txt files that are dispersed within the directory. What I want to do is automatically navigate the directory structure and when the process comes across the test.txt file it does some processing, when it is finished it navigates back and tries to find another test.txt file and so on until all files have been found and processed in the directory structure.
Anyone have any idea how I'd go about this...

Here, try this program

//where "directory" is the name of the directory through
//which php will search, including subdirectories.
searchfolder ("directory");

function searchfolder ($folder) {
//go through all the contents of the folder
$dir = opendir ($folder);
while (($file = readdir ($dir)) !== FALSE) {
if ($file != "." && $file != "..") {
if (is_dir ($folder."/".$file))
searchfolder ($folder."/".$file);
elseif ($file == "test.txt")
processfile ($folder."/".$file);
}
}
}

function processfile ($file) {
//here, enter what you want to happen with each file, given
//the file's name and path relative to this script
}

Hope that helps you out 🙂

Thanks for your reply Rohan but lets say I have a directory structure and files like /projects/text1/test.txt and /projects/text2/test.txt wouldn't your code just find the text1 directory and just process the test file in that directory. If I start the process again wouldn't it just repeat the find and process for /projects/text1/test.txt.
Ther could be multiple directories /projects/text2/test.txt........../projects/text56/test.txt

I need for all test.txt to be found and processed but only once.

Thanks

James

Rohan's script will iterate thru as many subdirectories as there are, processing each file it finds, and then it'll continue iterating through subfolders, folders etc untill all folders under the original foldername are all processed. <gasp>

Nice code.
