[SOLVED] List all files in a dir and subdirs

[Wuhtzu]

Hey

 

I have a directory /folder (which is actually /usr/home/web/[customer id]/folder when it comes to working with opendir()) and I would like to populate an array with name and location of all files found in the directory and it's subdirectories. Below are an example of a directory structure and the array I want to create from it:

 

Directory structure:

+/folder

|--file1.ext

|--file2.ext

|

|-+/subdir1

|  |--file1.ext

|  |--file2.ext

|

|--+/subdir2

    |--file3.ext

    |--file4.ext

    |-+/subsubdir1

    |  |--file3.ext

    |  |--file4.ext

 

Desired array:

Array
(
    [0] => Array
        (
            [file] => file1.ext
            [link] => /folder/file1.ext
        )

    [1] => Array
        (
            [file] => file2.ext
            [link] => /folder/file2.ext
        )

    [2] => Array
        (
            [file] => file1.ext
            [link] => /folder/subdir1/file1.ext
        )


    [3] => Array
        (
            [file] => file2.ext
            [link] => /folder/subdir1/file2.ext
        )

    [4] => Array
        (
            [file] => file3.ext
            [link] => /folder/subdir2/file3.ext
        )


    [5] => Array
        (
            [file] => file4.ext
            [link] => /folder/subdir2/file4.ext
        )


    [6] => Array
        (
            [file] => file3.ext
            [link] => /folder/subdir2/subsubdir1/file3.ext
        )


    [6] => Array
        (
            [file] => file4.ext
            [link] => /folder/subdir2/subsubdir1/file4.ext
        )

 

 

This is what I have come up with so far:

get_files_in_dir.php:

<?PHP

function get_files_in_dir($dir) {

//Check if opendir() can use $dir and open it
if($handle = opendir($dir)) {

	//Loop through $dir
	$i = 0;
	while (false !== ($file = readdir($handle))) {
		//Don't bother with the . and .. file/dir
  		if($file != "." && $file != "..") {
  		
  			//The full path to the file (or directory if $file is a dir)
  			$link = $dir . "/" . $file;
  		
  			//Check if $file is a dir
  			if(is_dir($link)){
  				
  				//The file was a dir so loop through that one too
  				get_files_in_dir($link);
  		}
  			else{ 
  				//The file was not a dir so it gets stored in the
  				//array $files[]. Both it's filename and path
  				$files[$i]["file"] = $file;
  				$files[$i]["link"] = $link;
  				$i++;
  			}
  		}
  	}
  
  //Close the dir
  closedir($handle);

//Print the array, just for the test phase
  print_r($files);
}
else {
return false;
}
}


//call the function:

$dir = "/usr/home/web/web115029/random/folder";
get_files_in_dir($dir);
?>

 

The function is "live" here and you can see its output - remember to view the source of the page for readable layout:

http://wuhtzu.dk/random/get_files_in_dir.php

 

As you can see my function creates a new array for each directory it finds because each time it finds a directory it calls it self again. Have you go any suggestions on how to proceed from here to achieve my goal?

 

Best regards

No suggestions?

I got it right:

 

<?PHP

function get_files_in_dir($dir) {


// Verify that $dir is a directory
if(is_dir($dir)) {


// $dirs_to_scan[] contains all the direcotries to scan. It begins by 
// containing only $dir (as specified in the function call, but gets
// populated as more directories are found inside the orginal $dir
$dirs_to_scan[] = $dir;

// count directories
$i = 0;

// count files
$j = 0;

// loop through $dirs_to_scan. Runs as long as $dirs_to_scan holds more entries than
// have already been scanned and counted by $i
while($i < count($dirs_to_scan)) {

	//Create handle for the current dir to scan
	$handle = opendir($dirs_to_scan[$i]);

	//Loop through the current dir ($dirs_to_scan[$i]
	while (false !== ($file = readdir($handle))) {
		//Don't bother with the . and .. file/dir
		if($file != "." && $file != "..") {

			//The full path to the file (or directory if $file is a dir)
			$link = $dirs_to_scan[$i] . "/" . $file;

			//Check if $file is a dir
			if(is_dir($link)){

				//$file was a dir so sign it up for scan
				$dirs_to_scan[] = $link;
			}
			else{ 
				//The file was not a dir so it gets stored in the
				//array $files[]. Both it's filename and path
				$files[$j]["filename"] = $file;
				$files[$j]["file"] = $link;

				//Add to the file count
				$j++;
			}

		}
	}
	//Close the currently open dir
	closedir($handle);

	//Add to the directory count
	$i++;
}


// Print the $dirs_to_scan array - JUST FOR THE TEST PHASE
print_r($dirs_to_scan);

// New lines to improve readability - JUST FOR THE TEST PHASE
echo "\n\n\n";

// Print the $files array - JUST FOR THE TEST PHASE
print_r($files);

}
else {
return false;
}

}


//call the function:
$dir = "/usr/home/web/web115029/random";
get_files_in_dir($dir);
?>

 

The function is "live" here:

Thanks to those who checked by...

Why not echo <pre> before your code and </pre> after it to save you having to view source all the time?

[Wuhtzu]

Do you mean echo for each cycle in the loop?

 

Well if I just wanted to see the output there wouldn't be any point in storing it in an array. It's for a file search function, so the print_r() is just for the testing the script and print_r() just looks horrible if you do not look at the source

 

 

[chigley]

Sorry, the forum parsed what I said... this Is what I meant to say:

 

<pre> before your code and </pre> after it

 

[Wuhtzu]

wow, neat trick. I guess everyone except me knew that was the way to make print_r readable I'll remember that. Thanks

The Proper Way to do this is
