Answer 1

There are two problems here:

1. You are only printing inside your foreach loop, not saving anything.
2. You are using the copy() function with the static filename file.pdf .

You will probably want to save all the files within your foreach loop and with either the same name or something random (otherwise, each save operation would overwrite the previous file.pdf ), something like this:

// Set your save path here
$path = '/home/igos/pdfs/';

foreach($output as $item){ 
    copy($item, $path . basename($item));
  }

That would save all the files, keeping their original filename to the /home/igos/pdfs/ folder.

Answer 2

i've solved it, using this code, thank you for @Oldskool :) :

<?php
set_time_limit(0);
include 'simple_html_dom.php';
$url='example.com';
//set your save path here
$path = '/home/igos/pdfs/';

$html = file_get_html($url) or die ('invalid url');
foreach($html->find('a') as $e) {
     $link= $e->href;
     if (preg_match('/\.pdf$/i', $link)) {
          $result[] = $link;
          copy($link, $path . basename($link));
     }
}

?>
