Great software!

Why PHPTracker? Because it’s not “just a tracker”, it contains a seeder server too so the distribution of your files is automatic. This is a big step for the content providers to adapt this amazing technology and change the stereotype that “torrent = warez”.

PHP based torrent file creator, tracker and seed server – PHPTracker.

ffmpeg-php – error: ‘PIX_FMT_RGBA32’ undeclared (first use in this function) | HOW GEEK!.

To fix this, replace PIX_FMT_RGBA32 with PIX_FMT_RGB32 .

You can use “rpl” to replace files recursively:

cd to the ffmpeg-php folder and run this command (beware!):

rpl -R PIX_FMT_RGBA32 PIX_FMT_RGB32 *

If rpl not installed on your system, install it, for example:

yum install rpl

Function below allow you to get count of Google backlinks for requested page

function getGoogleOuterLinksCount($url) {
 $domain = preg_replace('/^www\./','',array_shift(split('/',$url)));

 /*  I strongly recommend you to use www.google.<you country zone> version of Google */
 $html = "http://www.google.com/search?q=link:".$domain."&hl=en"; 

 $content = getRemoteFile($html);
 if (preg_match('/<div id=resultStats>(\d+) results/i',$content,$arr)) {
   $t = $arr[1];
   $t = str_replace(' ','',$t);
   $t = str_replace(',','',$t);
   return (int)$t;
 } else
   return 0;

It’s the best way to parse a string as Smarty template. You need to follow only 3 steps!

First of all we need to register a new template resource – string.

$smarty->register_resource("string", array("string_get_template",
 "string_get_timestamp",
 "string_get_secure",
 "string_get_trusted"));

Then add function implementations

function string_get_template ($tpl_name, &$tpl_source, &$smarty_obj) {
    global $smartyStringTemplates;
    $tpl_source = $smartyStringTemplates[$tpl_name];
    return true;
}

function string_get_timestamp($tpl_name, &$tpl_timestamp, &$smarty_obj) {
    // do database call here to populate $tpl_timestamp.
    $tpl_timestamp = time;
    return true;
}

function string_get_secure($tpl_name, &$smarty_obj) {
    // assume all templates are secure
    return true;
}

function string_get_trusted($tpl_name, &$smarty_obj) {
    // not used for templates
}

And the last step. Create an array of string templates and parse a string by passing it’s index in array

$smartyStringTemplates = array('{php}date(){/php}', '{$helloWold}');

print $smarty->fetch("string:1"); // will fetch a string {$helloWold}
