Question

$d = opendir(“docs”);

while (($file = readdir($d)) !== false) { 

    if (($file != ".") && ($file != "..")){
        }
}

I want to be able to display the first 5 file names.

Here is the twist, I have a next button, which I want to display the next 5 filenames

Thanks

You could use a counter variable, and make sure it doesn’t go to more that 5 ?

A bit like that :

$counter = 0;
$d = opendir("docs");
while (($file = readdir($d)) !== false && $counter < 5) { 
    if (($file != ".") && ($file != "..")){
        // ...
        $counter++;
    }
}

Not tested : maybe you’ll have to use <= instead of <
