Quick PHP help

Hey guys,

I'm putting in an upload/download script for a specific function in a sub-dir of my webpage. It's just a script I found on the net. This is the the function of the script that lists the files in the download directory.

/************************************************** **********
* List Files
************************************************** **********/
$handle=opendir($upload_dir);
$filelist = "";
while ($file = readdir($handle)) {
if(!is_dir($file) && !is_link($file)) {
$filelist .= "".$file."";
if ($DELETABLE)
$filelist .= " x";
$filelist .= " _{".date("d-m H:i", filemtime($upload_dir.$file))
."}
";
$filelist .="
";
}
}

What I need to do, is where it lists the current files in the diretory, when it lists them, I want it to make a link to the same file .. So.. like where it says $filelist .= "".$file.""; or whatever, I need it to do http://www.emedicine.com/med/topic280.htm

You concatenate strings with the period operator in php. i.e.

$filelist .= "<a href=\"" . $file . "\">" . $file . "</a>";

php is also capable of parsing unambiguous variables within double-quoted strings, so this works as well:

$filelist .= "<a href=\"$file\">$file</a>";

Personally, though, I avoid the latter method for clarity's sake.

Hey Man!

That seems to make sense. You're totally right, the first way is a lot more readable and makes it make more sense.

Thank you!
