将android中带有键和值的字符串发布到php

我想在我的android应用程序中，在一个数组中发送所有联系人姓名和号码的联系人，如 john=>“+92312xxxxxx”， 现在，我使用namevaluepairs发布两个数组，但它的工作方式不是： 公共类联系人列表扩展活动{

public TextView outputText;
   String phoneNumber = null;
   String names = null;
   String[] keyValue;
   String[] kes;
   int Count;

     fetchContacts();

            nameValuePairs.add(new BasicNameValuePair("CN[]", keyValue[i]));
            nameValuePairs.add(new BasicNameValuePair("names[]",kes[i]));

PHP在收到联系人后将匹配这些联系人，并只返回那些与数据库联系人匹配的联系人。然后它返回带有姓名的联系人 我被发送和接收部分卡住了 下面是php代码

<?php
define('DB_HOST', 'localhost');
 define('DB_NAME', 'verification'); 
 define('DB_USER','root'); 
 define('DB_PASSWORD',''); 

 // 1. Create a database connection
$connection = mysqli_connect(DB_HOST,DB_USER,DB_PASSWORD);
if (!$connection) {
    die("Database connection failed: " . mysqli_error());
}

// 2. Select a database to use 
$db_select = mysqli_select_db($connection, DB_NAME);
if (!$db_select) {
    die("Database selection failed: " . mysqli_error());
}

$PhoneNum= $_POST["CN"];
$i=0;
$j=0;
$friends = array();
$Invite = array();
unset ($PhoneNum[0]);
foreach ($PhoneNum as $i=> $element){

 //or do whatever you need to do to that variable
$query="SELECT Number FROM `user` WHERE Number=$element";
$query_exec = mysqli_query($connection ,$query);
if (!$query_exec)
{  echo mysql_error(); }
ELSE {
if(mysqli_num_rows($query_exec)>0)
{
$friends["$j"]= $PhoneNum[$i];

$j++;
}
else
{
;
}}
}
echo (json_encode($friends));

?>
