Im tryig to add some php code to my php script, this is for a domain license but every time I add the code I get an error, the trouble is I dont know what the error is, I hope you dont mind helpng me out with this:

This is the original php code,

<?php

class VidRipScript
{
function VidRipScript()
{
$this->Smarty =& GetInstance('Smarty');
$this->PluginController =& GetInstance('PluginController');
require('config.php');
$this->Config = $Config;
return true;
}

// rip url
function Rip($url)
{
if(!$url || !parse_url($url))
{
$this->Smarty->assign('RIP_FAILED', true);
return false;
}

if($this->Config['Pipe'])
{
$pipe = ' | ' . $this->Config['Pipe'];
}

switch($this->Config['downloader'])
{
case 'curl':
$download_cmd = $this->Config['curl_path'] . ' -L';
break;
case 'wget':
$download_cmd = $this->Config['wget_path'] . ' -O -';
break;
default:
$download_cmd = $this->Config['downloader'];
}

ob_start();

// before ripping
$this->PluginController->RunEvent('BeforeRipping');
passthru(sprintf('%s "%s" | %s -f flv -i - -f mp3 -title "%s" -author "%s" -comment "%s" -%s', $download_cmd, $url, $this->Config['ffmpeg_path'], $this->Config['title'], $this->Config['author'], $this->Config['comment'], $pipe));

// after ripping
$this->PluginController->RunEvent('AfterRipping');
header('Pragma: public');
header('Expires: 0');
header('Content-Type: audio/mpeg');
header(sprintf('Content-Disposition: attachment; filename="%s-%s.mp3"', $this->Config['filename_prefix'], time()));
ob_end_flush();

// after download
$this->PluginController->RunEvent('AfterDownload');
exit;
}

// find FLV
function FindFLV($url)
{
$URLInfo = parse_url($url);
$host = explode('.', $URLInfo['host']);
$host = strtolower($host[count($host) -2]);
if(file_exists('modules/' . $host . '.def.php'))
{
require_once('modules/' . $host . '.def.php');
return RunModule($url);
}
$this->Smarty->assign('NOT_SUPPORTED', true);
return false;
}
}
?>


This is the domain license code and it needs to be inserted into an important file like the one above:

// PLEASE DO NOT EDIT BELOW
// PLEASE DO NOT EDIT BELOW
// PLEASE DO NOT EDIT BELOW

function p($b,$e,$m) {
$a = 1;
$i = 0;
$b2 = $b;
while (($e >> $i)>0) {
if ((($e >> $i) & 1) == 1) {
$a = mo(($a * $b2) , $m);
}
$b2 = mo(($b2 * $b2) , $m);
$i++;
}
return $a;
}

function mo ($g, $l) {
return $g - ($l * floor ($g/$l));
}

function d($c, $d, $n) {
$da = split(" ", $c);
for ($u=0; $u<count ($da); $u++) {
if ($da[$u] == "") {
array_splice($da, $u, 1);
}
}

for ($u=0; $u< count($da); $u++) {
$rm = p($da[$u], $d, $n);
$de.= substr ($rm, 1, strlen($rm)-2);
}

for ($u=0; $u<strlen($de); $u+=2) {
$rd .= chr(substr ($de, $u, 2) + 30);
}
return $rd;
}

}

if(!$licerror)
{
$f=fopen("$v"."_$p.key","w");
fwrite($f,$newkey);
}
}

if($licerror)
{
die($licerror);
}



This is the error I get when I insert the code:


Warning: fopen(15_56.key) [function.fopen]: failed to open stream: Permission denied in /home/vidrip/public_html/electrifire/vidrip/VidRipScript.class.php on line 96

Warning: fwrite(): supplied argument is not a valid stream resource in /home/vidrip/public_html/electrifire/vidrip/VidRipScript.class.php on line 97



The domain license code needs to be inserted within the php tags and I believe it should be at the top of the php code but what is te error?


Sorry for the lengthly post but really stuck

$f=fopen("$v"."_$p.key","w");
fwrite($f,$newkey);
}

Seems to be the problem
Its being denied permission. Using "w" - if the file does not exist, attempt to create it. Does the file exist? Does it have permission to create it if it doesnt exist?

"If you fopen() a handle, you also have to obligation to fclose() it again."
$f=fopen("$v"."_$p.key","w");
fwrite($f,$newkey);
fclose($f);
}

Search fopen and fwrite at php.net
Might find some answers
