Directory recursion has angered me many long nights. Here is what I
finally came up with, which works perfectly. This should be easily
changed into what you need.. it's just an example of the logic. ;)
This was meant to run from the command line with /usr/bin/php -q ;)
$base = $argv[1];
$i = 0;
$directory[$i] = array ($argv[1]);
while (1) {
if ( @ is_array ($directory[$i])) {
$subdirs = "";
foreach ($directory[$i] as $dir) {
if (($dir_handle = @ opendir ($dir))) {
print ("Reading $dir\n");
while (($file = readdir ($dir_handle)) !==
false) {
// Drop these two, else we'll be no better
// than glibc's glob() ;)
if (($file != '.') && ($file != '..')) {
if ( ! ereg ('^/', $dir)) {
$temp = $base . $dir;
} else { $temp = $dir; }
if ( ! ereg ('/$', $temp)) {
$temp .= '/' . $file;
} else { $temp .= $file; }
// Consider dropping symlinks right here,
// or treating them as a normal file.
if ( @ is_dir ($temp)) {
$subdirs .= $temp . ',';
} else { print ("\t$file\n"); }
}
}
closedir ($dir_handle);
}
}
$i++;
if ($subdirs) {
$directory[$i] = explode (',', substr ($subdirs, 0, ((strlen
($subdirs) - 1))));
}
}
else { break; }
}
Hope that helps a bit. I know that was one of the most frustrating things
I've ever tried to figure out (in any language). It's certainly not
perfect.. you will probably need to add a few more string checks to it,
but the basic logic seems flawless to me.
Good luck! ;)
