要在$ zip-> extractTo中合并而不是替换

Question

I have used the following code to unzip a zip folder after upload.

  /* here it is really happening */

    if(move_uploaded_file($source, $targetzip)) {
        $zip = new ZipArchive();
        $x = $zip->open($targetzip);  // open the zip file to extract
        if ($x === true) {
            echo $targetdir; exit;
            $zip->extractTo($targetdir); // place in the directory with same name  
            $zip->close();
            unlink($targetzip);
        }
        $message = "Your .zip file was uploaded and unpacked.";
    } else {    
        $message = "There was a problem with the upload. Please try again.";
    } 

It is working fine. But the only problem is the that the folder is replaced by the new one uploaded. I want to merge it.

Suppose i have a zip folder. One.zip a b c

When i upload this, it should merge with the (One) folder which is already in the upload server. So the previous folders in the (One) folder should not be replaced.

I think It is understandable now. Please help to do the trick.

You can con-cat current time & date with you target fine name:

$targetdir = $targetdir."_".str_replace(' ',"/",date('Y-m-d H:i:s'));

Using this logic, you fine will not replace with previous file.
