<?PHP
function readCSV($csvFile){
    $file_handle = fopen($csvFile, 'r');
    while (!feof($file_handle) ) {
        $line_of_text[] = fgetcsv($file_handle, 20000);
    }
    fclose($file_handle);
    return $line_of_text;
}


// Set path to CSV file
$csvFile = 'test.csv';

$csv = readCSV($csvFile);
echo '<pre>';
print_r($csv);
echo '</pre>';

//sortinng by pos ke 1
$pos=1; //dimulai dari 0 tp saya milih 1
$data=array();
foreach($csv as $id=>$arr){
   $id2=sprintf("%09s",$id);
   $data[ $arr[$pos].$id2 ] = $arr;
}
ksort($data);
echo '<pre>'.print_r($data,1).'</pre>';
?>
