I need a multiple file uploader created by pure jquery/Javascript and php5. Not use any flash files. If any body have code for that please share with me. I tried with File API but its not supporting IE and Opera.

You can use blueimp jQuery File Upload for the client side to have multiple file uploads. Has many options, is customizable.

For a PHP side you may be interested in some ideas on what to do (just some snippet for my upload form for images, so some variables are not defined here like $log or $confImages, but you can get the idea):

            //Сheck that we have a file
            if (empty($uploaded_image))
            return false;
        if ($uploaded_image['error']) {
            $log->LogError($uploaded_image['error'] . ": Error uploading file.");
            return false;   
        }

        list($dirname, $basename, $extension, $filename) = array_values(pathinfo($uploaded_image['name'])); //Extract variables: dirname, basename, extension, filename
        //Normalize file name. I may suggest using http://cubiq.org/the-perfect-php-clean-url-generator than this
        $filename = iconv("utf-8","ascii//TRANSLIT",$filename);
            $allowedExt = array("jpg","jpeg","gif","png");
        $extension = strtolower($extension);

        //Check if the image has allowed type
        if (empty($extension) || !in_array($extension, $allowedExt)) {
            $log->LogError("invalid_extension: Not allowed to upload file ".(empty($extension) ? "without extension" : "with extension $extension").". Allowed Extensions: ". implode(",",$allowedExt));
            return false;   
        }

            //Generate some random string in case if such file exists on server
        $postfix = substr( md5(uniqid(rand(),1)), 3, 5 );
        $newFile = $_SERVER['DOCUMENT_ROOT'].$upload_folder."/".$filename.'_'.$postfix.'.'.$extension; //new filename with appended random string to original filename);

        //Check if the file with the same name is already exists on the server
        if (file_exists($newFile)) {
            $log->LogError("file_exists: File couldn't be uploaded, because such filename exist ".basename($newFile)." jau eksistē");
        }

        //Attempt to move the uploaded file to it's new place
        if (move_uploaded_file($uploaded_image['tmp_name'],$newFile)) {
            //I do some resizing also using http://phpthumb.gxdlabs.com/
            $convertedimage = PhpThumbFactory::create($newFile, array("jpegQuality" => 80));
            if (isset($confImages["max_width"]) || isset($confImages["max_height"])) 
                $convertedimage->resize($confImages["max_width"], $confImages["max_height"]);
            $convertedimage->save( $newFile );

            //Save image path to database
            ...

            return $image;
        } else {
            $log->LogError("Couldn't copy file from temp folder " . $uploaded_image['tmp_name'] . " to location " . $newFile);
        }       

        return false;
