What would you like to do?
$term = $_GET['term'];
$r = new Redis("","6379");
$items = $r->zrangebylex("kernel","[$term","[$term\xff",Array("LIMIT","0","10"));
$t = Array();
$id = 0;
foreach($items as $item) {
$t[] = Array("id" => $id++, "label" => $item);
$json = new Services_JSON();
$output = $json->encode($t);

It is preferred to use the native functions json_encode and json_decode of PHP instead of the class Services_JSON.

Also the code below is for PHP >= 5.4


    $term = $_GET['term'];

    $r = (new Redis("","6379"))->connect();
    $items = $r->zrangebylex("kernel","[$term","[$term\xff",["LIMIT","0","10"]);

    $t = [];
    $id = 0;
    foreach($items as $item) {
        $t[] = ["id" => $id++, "label" => $item];
    echo json_encode($t);

I wrote something for nodejs if anyone is interested. It uses the same jquery UI autocomplete widget as but it executes a function as the source value.

edit: oh and btw I'm a novice so idk how good this code is, but it works.

On the server it uses and the [redis]( /redis) npm module.


var redis    = require('redis');
var client   = redis.createClient();
var io       = require('')(8000);

io.on('connection', function(socket) {                                 

  socket.on('keypress', function(data, fn) {
    //DBKEY is the key to the values you want     
    client.zrangebylex(['DBKEY', '[' + data, '[' + data + 'z'],
      function (err, response) {                                       
        if (err) throw err;                                            



//set this function to be called as the `source` in the jquery autocomplete widget
function sourceFunc(request, response) {             
  socket.emit('keypress', request.term, function(data) {

I am unsure how this works as I cannot find support for zrangebylex with PHP anywhere.

Seems like demo script doesn't work for several years :-(

You can use predis library and call ZSetRangeByLex

By any chance has anyone an example project on how to store the data, index it and the UI for autocomplete?

Thank you in advance.
