Question

I have a folder in which there are 12 files, in php i am send two request parameters are:

$from = $_REQUEST['from'];
$to = $_REQUEST['to'];

means if i write there from 1 to 9, then i’ll get all files which is in array as:

 $path = 'example/'
    $files = scandir($path);

    $fi = array();
    foreach ($files as $file) {
    $fi[] = $file; --> array
    }

all file ranges which i am specified using request parameters are display files using through echo or explode, i am trying this, if there is more efficient way then please enlighten on this problem.

Answer 1

You can use array_slice:

$fi = array_slice($files, $from, $to - $from);

If $_REQUEST[from] and [to] are 1-indexed, simply substract 1 from both:

$from = $_REQUEST['from'] - 1;
$to = $_REQUEST['to'] - 1
