how to prevent extracting a php file from zip

i am using this piece of code to unzip a .zip file

$zip = new ZipArchive;
if ($zip->open('test.zip') === TRUE) {
   $zip->extractTo('/my/destination/dir/');
   $zip->close();
   echo 'ok';
} else {
   echo 'failed';
}

Lets say: there is a .php file in the .zip and i do not want a .php file to be extracted. How can i prevent that?

$zip= new ZipArchive;
if($zip->open('test.zip') === TRUE){
 for($i = 0; $i < $zip->numFiles; $i++) {
  $filename = pathinfo($zip->getNameIndex($i));
  $fileinfo = $filename['extension'];
  if($fileinfo!="php"){
    $zip->extractTo('extract/',$zip->getNameIndex($i));
  }
  $zip->close();
}

You can try something like this for PHP >= 5.5:

$zip = new ZipArchive;
if ($zip->open('test.zip') === TRUE) {

 for ($i = 0; $i < $zip->numFiles; $i++) {
     if( pathinfo($zip->getNameIndex($i)['extension'] != "php")){
        $zip->extractTo('/my/destination/dir/', $zip->getNameIndex($i));
     }
}
   $zip->close();
}

Or this for PHP < 5.5:

$zip = new ZipArchive;
if ($zip->open('test.zip') === TRUE) {

 for ($i = 0; $i < $zip->numFiles; $i++) {
     $path_info = pathinfo($zip->getNameIndex($i));
     $ext = $path_info['extension'];
     if( $ext != "php")){
        $zip->extractTo('/my/destination/dir/', $zip->getNameIndex($i));
     }
}
   $zip->close();
}

The only difference between the two is the pathinfo function. Both will loop all files inside the zip file and, if the file extension isn't php, extracts it to /my/destination/dir/.
