ok, basically I need a way to turn this:
Into this:
Code: Select all
$folder = C:/bla/bla/
$filename = egg.zip
How would I go about doing this, this has to work for file names that are any length.

This may not invlove php (i'm not sure) but is it possible to open for example my documents from a webpage? Ive tried a few ways but no luck, it either does nothing at all or just shows a page cannot be found message.

find the last occurence of '/' using regex and find the length of the string.
If you have the position of the last occurence of '/', then you can read each character from then to the length of the string - 1

this idea seems to be easier
Code: Select all
<?
$path = "/home/httpd/html/index.php";
$tempArray = explode("/", $path);
echo "filename:".$tempArray[count($tempArray) - 1];
?>

Works brilliant cheers, but unfortunatley its basically useless unless you can popup a local folder from a link or automatically.

not really understood wot you meant.
this is used to get the directory of a file path.
Code: Select all
<?
$path = "/home/httpd/html/index.php";
$tempArray = explode("/", $path);
echo "filename:".$tempArray[count($tempArray) - 1]."<br />";
for($i = 1; $i < count($tempArray) - 1; $i++)
$dirPath .= "/".$tempArray[$i];
echo $dirPath;//prints directory path
?>
if you want the path of a currently running doc, use $_SERVER['DOCUMENT_ROOT']
look at $_SERVER globals for more options

basically what I want is too very simply link to a folder on the users machine, eg if the user browses to the folder C:\stuff\ and submits then the script pops it open, I need to know how to open users folder from a webpage.
