(php) read plugin informations

hello everyone,
can someone tell me how to read the name, main and version information of a plugin with php?

i want to write a pluginlist in php with the installed plugins and i need all informations for an updatecheck, but dont know how to get these informations out of the .jar-file

does someone have a simple code snippet to do that, or do i need another plugin to export the informations?

 

Code:

<?php
 
function getPluginInfo($jarfile){
    $pdf_array = yaml_parse(file_get_contents('zip://' . $plugin_file . '#plugin.yml'));
 
    $plugin['name'] = isset($pdf_array['name']) ? $pdf_array['name'] : 'Unknown';
    $plugin['version'] = isset($pdf_array['version']) ? $pdf_array['version'] : '0.1';
    $plugin['main'] = isset($pdf_array['main']) ? $pdf_array['main'] : 'null';
 
    return($plugin);
}
 
//Example
 
$we = getPluginInfo('/home/bukkit/plugins/WorldEdit.jar');
?>
<p>Name: <?=$we['name'];?></p>
<p>Version: <?=$we['version'];?></p>
<p>Main class: <?=$we['main'];?></p>
