Re: [PHP] Directory Walking From: Hans H. Anderson (me <email protected>)

Alex,

This was just a quick and dirty attempt, but it seems to work. Maybe it
can help you get to where you want: 

----
<?php

if(!isset($dir)) $dir = "/home/hans/www/clients/solplex/htdocs";

if(ereg("\.{2,2}$",$dir)) {
	$fix = explode("/",$dir);
	$c = count($fix);
	// could use array_splice here, if using version of PHP with it
	unset($fix[$c-1]);
	unset($fix[$c-2]);
	$dir = implode("/",$fix);
}

print "<b>$dir</b><br><br>";

$d = opendir($dir);

while($f = readdir($d)) {
	if(is_dir($f)) print "<a href=\"$PHP_SELF?dir=" . urlencode($dir . "/$f") . "\">$f</a><br>\n";
}
closedir($d);

?>
