Hi..I'm getting problem to store the output of this php code into multiple text files. Can anyone sugeest. Here is my code:

<?php

for($i=1; $i<=100; $i++)
{


$html = file_get_contents("$i.html");
$dom = new DOMDocument;

//Parse the HTML. The @ is used to suppress any parsing errors

@$dom->loadHTML($html);


$links = $dom->getElementsByTagName('a');


foreach ($links as $link){

   $output= $link->getAttribute('href'), '<br>';

}

$ourFileName = "$i.txt";
$fp = fopen("$i.txt", "w");
fputs ($fp, $output);
fclose($fp);


}

?>`
