function getMergePaths($pathArray){
    $result = [];
    foreach($pathArray as $path){
        $basepath = dirname($path);
        $basename = basename($path);
        if(isset($result[$basepath])){
            $result[$basepath] .= ','.$basename;
        }else{
            $result[$basepath] = $basename;
        }
    }
    return $result;
}
