Goody - a recursive routine. I have just the thing-
// Dirs you don't want listed
$badlist = "secret phpMyAdmin stats test tools";
$bad_dirs = explode(" ", $badlist);
$docroot = "/usr/local/apache/htdocs/";
$basedir = $docroot;
function read_files($dirname) {
global $filelist;
$dirid = opendir($dirname);
while($entry = readdir($dirid)):
$this = $dirname . '/' . $entry;
if ( (is_file($this)) && ($entry != ".") && ($entry != "..") &&
(!eregi("old$",$entry)) && (!eregi("bck$",$entry)) && (strstr($this,
".htm") || strstr($this, ".html") || strstr($this, ".php"))):
$filelist[] = $entry;
endif;
endwhile;
}
function exclude_dir($dirname) {
global $bad_dirs;
$outcome = false;
while(list($key, $value) = each($bad_dirs)):
if (strstr("$dirname", "$value")):
$outcome = true;
endif;
endwhile;
reset($bad_dirs);
return $outcome;
}
function recurse_dir($basedir) {
global $dirlist;
$dirid = opendir("$basedir");
while ($entry = readdir($dirid) ) {
$this = $basedir . $entry;
if ( (is_dir($this)) && ($entry != ".") && ($entry != "..") &&
(!exclude_dir("$this/"))) {
$dirlist[] = $this;
recurse_dir("$this/");
};
};
};
?>
Call it with recurse_dir(dir-to_start) and get the results in $dirlist[]
Have fun. And yes, there's room for improvement, having looked at it for
the first time in a year or so :-) The first obvious would be to return
$dirlist....
