PHP 5.3 ZipArchive问题

Question

I have 5 accounts hosted at the same hosting plan, to each account I load my PHP CMS, hand made.

I Upload a CMS.zip and an UnZip.php file, the entire system works fine as long as the server is configured to work with PHP 5.2.

Recently I encountered an issue with my latest account configured as PHP 5.3, the CMS code is the same, But does not work, after a long and exhausting conversation with the support, they resolved that my code is set to extract only with PHP 5.2 not with 5.3.

I use a standard PHP ZipArchive Class to handle extractions, which is why I found this weird, in any case I searched for a proper handle to un zip with PHP 5.3 but with no luck.

Can someone please tell me how this code, attached to this question, should be written? Ps the support mentioned that the ZipArchive class is in fact active on the server.

Here is my code:

   $DIR_NAME = getcwd();

    $zip = new ZipArchive;
    if ($zip->open('ZipTest.zip') === TRUE) {
        $zip->extractTo($DIR_NAME);
        $zip->close();

        if(file_exists('editor.php')){
            echo '<u style="color:Green;">File Found ::   Extraction Complete !!</u><br>';
            echo $DIR_NAME.' : 
        <b style="color:orange;">ZipTest.zip Activated Seccessfully!</b> <a href="dir_inventory.php">Load CMS</a><br>';
        }
        else {
            echo '<u style="color:red;"><b> ERORR </b>::   Extraction Failure !!</u><br>';

        }
    } 
    else {
        echo '<b style="color:red;">Cant Exctract ZipTest.zip file to location!</b>';
    }

Here is my class to work with Zip.

I have no trouble with it on PHP 5.3.8.

<?php

/**
 *  @author         Andrew Zavadsky <zaffaccky@gmail.com>
 *  @class          Zip
 *  @description    Class for manipulation ZIP (creating, unzipping)
 */

class Zip
{
    private $zip            = null;

    public function __construct($src)
    {
        $this->zip  = new ZipArchive();

        if (!file_exists($src))
            $r = $this->zip->open($src, ZipArchive::CREATE);
        else
            $r = $this->zip->open($src);
    }

    public function addFromString($as, $text)
    {
        $this->zip->addFromString($as, $text);

        return $this;
    }

    public function addFile($as, $src = null)
    {
        if ($src && file_exists($src))
            $this->zip->addFile($src, $as);
        else
            $this->zip->addFromString($as, '');

        return $this;
    }

    public function unzip($to, array $files = array())
    {
        if (!file_exists($to))
            mkdir($to);

        if (!is_writable($to) || !is_dir($to))
            throw new Exception(sprintf('Target directory %s is not directory or not for writing', $to));

        if (count($files))
            $this->zip->extractTo($to, $files);
        else
            $this->zip->extractTo($to);

        $this->zip->close();

        return $this;
    }

    public function addFolder($as, $src = null)
    {
        $as = trim($as, '\\/');

        $this->zip->addEmptyDir($as);

        if ($src && file_exists($src) && is_dir($src))
            $this->addFiles($src, $as);

        return $this;
    }

    private function addFiles($from, $to = '', $recursive = true)
    {
        $from   = rtrim($from, '\\/');
        $to     = trim($to, '\\/');

        if (!is_dir($from))
            throw new Exception(sprintf('Can\'t add files from folder %s', $from));
        else
            $this->zip->addEmptyDir($to);


        foreach (scandir($from) as $i => $f)
        {
            if ($i <= 1)
                continue;

            if (is_dir($file = $from . DIRECTORY_SEPARATOR . $f) && $recursive)
                $this->addFiles($file, $to . DIRECTORY_SEPARATOR . $f, $recursive);
            else
                $this->addFile($to ? $to . DIRECTORY_SEPARATOR . $f : $f, $file);
        }

        return $this;
    }
}

Try it, you need $zip->unzip($to, $options);
