create url link from variable filename

flashharry82

I have a list of file names and want to make them into links. The list is produced from a variable $file being out put.

I saw the link() function but not quite sure how to use it. Would it be something like,

link(c:\root\$file);

Not really sure. Any suggestions?

Hello, flashharry82,

link() is not the right function to use.

If $file is an Array, then you cna do something like this:

foreach($file as $f) {
echo '<br><a href="'.$f.'">'.$f.'</a>';
}

assuming that the files are in the right place.

If you can give me an example of what $file looks like, and what your $DOCUMENT_ROOT is, I can be more specific.

Thanx But.........
Now I'm gettin this error message

Warning: Invalid argument supplied for foreach() in D:\Inetpub\wwwroot\readdir.php on line 16

that is the actual path name to the file.

Here is the bit of code for readdir.php

<?php
$dh = opendir("D:\Inetpub\wwwroot\documents_basic");
$filename = $_POST["directory"];
while (!(($file = readdir($dh))===false)){
if(stristr($file, $filename)){
if(strstr($file, ".")){
print"$file<br>";
foreach($file as $f){
echo'<br><a href="'.$f.'">'.$f.'</a>';
}
}
}
}
closedir($dh);
?>

Never mind, I cracked it anyway.

Although if you could show me a way to search the whole site for files instead of just a specific directory I'd be most appreciative.

Go and have a look at the php.net 404 error file. It uses this technique to search the site.
