PHP Directory Search

[andrewsmd]

I have a program that searches directories for a wild card. i.e. C:\some folder\*.txt would return any file with a .txt extension in the path C:\some folder. Let's say that these files are in c:\some folder

test.txt
test2.txt
folder1 (a folder)
folder2 (another folder)

Now I would like to be able to realize that folder1 and 2 are folders and then in turn search within them. I would like to repeat that for any folders within them and so on. Here is the code I have so far

//an array of the results
$arrayReturn = array();

//an array of the files
$input = glob("c:\\some folder\\*.txt");

foreach($input as $i){

//if it is a folder
if(is_dir($i)){

//we have a directory and I need to search it again.
//i don't know what to do here

}//if

//else it is a file
else{
array_push($returnArray, $i);
}
}//foreach

How would I keep going on and then searching folders within itself. Does this require some kind of recursion? Thanks,

How *I* would approach this is
1. Build a list of directories
2. build the list of the main target directory
3. Loop through the directories for files and add them to that list.

// Or make $filetypes a scalar, in which case you can  
// eliminate the foreach on $filetypes 
$filetypes = Array('*.txt'); 
$arrayReturn = Array(); 
$directories = Array(); 
//The target directory. 
$targetDirectory ="c:\\some-folder"; 

if ($handle = opendir($targetDirectory)) { 
 while (false !== ($file = readdir($handle))) { 
  if(is_dir($file)){ array_push($directories,$file); } 
  else { 
   foreach ($filetypes as $type) { 
    if (preg_match("/$type$/i",$file)) { array_push($arrayReturn,$file); } 
 } 
  } 
 } 
 closedir($handle); 
} 
// If there's no directories, this does nothing 
foreach($directories as $dir){ 
 if ($handle = opendir("$targetDirectory\\$dir")) { 
  while (false !== ($file = readdir($handle))) { 
   foreach ($filetypes as $type) { 
    if (preg_match("/$type$/i",$file)) { array_push($arrayReturn,"$dir\\$file"); } 
 } 
  } 
  closedir($handle); 
 } 
} 
header("Content-type:text/html\n\n"); 
print "<ul>\n"; 
foreach ($arrayReturn as $file) { print "<li>$file </li>\n"; } 
print "</ul>\n"; 
// or var_dump($arrayReturn) 

So your potential list would be

file1.txt
file2.txt
folder1/file1.txt
folder1/file2.txt
folder2/file1.txt
folder2/file2.txt
