jquery tokeninput very slow

Question

I am using Jquery TokenInput with php 5.5.8. I take query from my database but it is very slow. Before it will display a result, it takes some time. I have only few informations in my database (2 line)

This is my code which generate the json for me after making the search

This is my code that i use to make the search. I don't know why it is so slow

<?php
session_start(); 
# Connect to the database

require('fonctions.php');
require('configurations.php');
//require('encodage.php');


$q=addslashes($_REQUEST['q']);

$q =mysqli_real_escape_string($connection, $q);



//On effectue une opération que si on a mis au moins 1 caractere
$notre_tableau=explode(',',$q);


$compter_tableau=count($notre_tableau);

$username =  $_SESSION['username'];
$id_super_admin = $_SESSION['id_super_admin'];


//On recupere là où l'id super admin est egale a l'id du super admin

$req_search = "SELECT id_ojm_peoples, nom, prenom, countrycode, id_city  

FROM  ojm_peoples

WHERE id_super_admin='$id_super_admin' AND  ";

for ($i = 0; $i < $compter_tableau; $i++) 
{
$notremotchercher=trim($notre_tableau["$i"]);


if($i==$compter_tableau) { $liaison="AND"; } else { $liaison=""; }

if($i!=0) { $debutliaison="AND"; } else { $debutliaison=""; }

//On n'effectue la recherche que si c'est un truc non vide

if($notremotchercher!='')
{
$req_search .= "$debutliaison (nom LIKE '%$notremotchercher%' OR prenom LIKE '%$notremotchercher%')  $liaison";

{
    $requete=mysqli_query($connection, "$req_search LIMIT 20") or die(mysqli_error($connection));



    $tableau=array();

    $tableau_valeur=array();



    # Collect the results
    while($affichage = mysqli_fetch_assoc($requete))

    for($i=0;$i<$compter;$i++)

    $valeur_tableau = $tableau_valeur["$i"];

    $valeur_tableau_i = $tableau["$i"];

    }
    //Fin de l'affichage de la forme Json 
    echo ']';

//Fin du cas ou le mot rechercher n'est pas vide

mysqli_close($connection);


?>

And this is my configurations.php code

    $mysqlport = @getenv('S2G_MYSQL_PORT');

    $mysqlhost = "localhost:".@$mysqlport;

    //Le host recuperé du formulaire
    $mysql_host='localhost';

    $root = 'root';
    $dbpassword ='';    

    $db = 'johnmax';

/*Si le port mysql ne donne rien, on donne la valeur donne par defaut emise par le formulaire*/

    if (@$mysqlport=="") 
    {

        $mysqlhost = $mysql_host;
    }

/////////////////// 





    $connection=mysqli_connect($mysqlhost,  $root, $dbpassword, $db) or die(mysqli_connect_error($connection)); 

Answer 1

Everything looks normal in your code. I had faced something similar in the past and in my case it was due to the fact that I was in local and I was using localhost as host of the server instead of 127.0.0.1 while using easyphp.

So replace localhost with 127.0.0.1 in your config file.

Also, if you are using Php 5.5, why don't you use json_encode instead of creating manually your json. Your way of generating json manually might also be generating an error along the road.
