Verzeichnis auslesen

[Christoph Weis]

Hallo,

folgendes kleines Skript zeigt leider kein Ergebnis an:

<?PHP
function getImagesFromPa th($path)
{
$result = array();

$handle=opendir ($path);

while ($file = readdir ($handle))
{
if ($file != "." && $file != "..")
{
if (! is_dir($file))
{
$sub = substr($file, -4);
if ($sub == ".pdf")
$result[] = $file;
}
}
}

return $result;
}

$fileNames = getImagesFromPa th("./data");
$num = count($fileName s);

for ($x=0;$x<$num;$ x++)
{
echo "$fileNames[x]<br>";}

?>

Wenn ich aber folgendes verwende : echo "$filename[1]";
sehe ich den Inhalt von $filename.
Stimmt an der Schleife etwas nicht?

Gruß

You should check if this worked.

if (!$handle)
return FALSE; // or whatever is appropriate
[color=blue]

Should be:

while (($file = readdir($handle )) !== FALSE)

Think of what happens if you get a file named "0" ?

That should give a warning if you have error_reporting set high enough. You're
using 'x' as an array key - not the variable $x.

Presumably you mean:

echo $filenames[$x] . '<br>';

Or:

echo "{$filename s[$x]}<br>";

But there isn't a '$filename' variable anywhere in your post. There's
$fileNames though?
