PHP：realpath，windows和unix路径之间的区别

Question

我知道windows和unix路径之间的函数realpath的结果存在差异

我有这个功能用于创建一个zip，我不知道如何将它转换为在windows和unix上工作（现在只适用于unix）

function ZIP($source, $destination){

       if (!extension_loaded('zip') || !file_exists($source)) {
           return false;
       }

       $zip = new ZipArchive();

       if (!$zip->open($destination, ZIPARCHIVE::CREATE)) {
           return false;
       }

       $source = str_replace('\\', '/', realpath($source));

       if (is_dir($source) === true){
           $files = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($source), RecursiveIteratorIterator::SELF_FIRST);

           foreach ($files as $file){
               $file = str_replace('\\', '/', $file);

               // Ignore "." and ".." folders
               if(in_array(substr($file, strrpos($file, '/')+1), array('.', '..')))
                   continue;

               $file = realpath($file);

               if (is_dir($file) === true){
                   $zip->addEmptyDir(str_replace($source . '/', '', $file . '/'));
               } else if (is_file($file) === true){
                   $zip->addFromString(str_replace($source . '/', '', $file), file_get_contents($file));
               }
           }
       }else if (is_file($source) === true){
           $zip->addFromString(basename($source), file_get_contents($source));
       }

       return $zip->close();
 }

我认为DIRECTORY_SEPARATOR常量可以帮助转换

更新

这适用于windows和unix

function Zip($source, $destination){

if (!extension_loaded('zip') || !file_exists($source)) {
    return false;
}

$zip = new ZipArchive();
if (!$zip->open($destination, ZIPARCHIVE::CREATE)) {
    return false;
}

$source = str_replace('\\', '/', realpath($source));

if (is_dir($source) === true)
{
    $files = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($source), RecursiveIteratorIterator::SELF_FIRST);

    foreach ($files as $file)
    {
        $file = str_replace('\\', '/', $file);

        // Ignore "." and ".." folders
        if( in_array(substr($file, strrpos($file, '/')+1), array('.', '..')) )
            continue;

        if (is_dir($file) === true)
        {
            $zip->addEmptyDir(str_replace($source . '/', '', $file));
        }
        else if (is_file($file) === true)
        {

            $str1 = str_replace($source . '/', '', '/'.$file);
            $zip->addFromString($str1, file_get_contents($file));

        }
    }
}
else if (is_file($source) === true)
{
    $zip->addFromString(basename($source), file_get_contents($source));
}

return $zip->close();
}
