How to output a JSONArray from a webservice written in PHP - php

Question

I have webservice written in PHP that reads from the local database and output the result in JSON.
However, I am unable to output it into a JSONArray.
Here is the php script
<?php
$username = "root";
$password = "";
$hostname = "localhost";
$response=array();
//connection to the database
$dbhandle = mysql_connect($hostname, $username, $password)
or die("Unable to connect to MySQL");
//select a database to work with
$selected = mysql_select_db("test",$dbhandle)
or die("Could not select test");
//execute the SQL query and return records
$result = mysql_query("SELECT name, country FROM android");
$response["infos"] = array();
while ($row = mysql_fetch_assoc($result)) {
$info = array();
$info["name"]=$row["name"];
$info["country"]=$row["country"];
print(json_encode($info));
}
//close the connection
mysql_close($dbhandle);
?>
This is the output from the webservice
{"name":"develop","country":"mru"}{"name":"fufu","country":"tutu"} {"name":"chikaka","country":"aceVentura"}
But I have been told that this is not in JSONArray.
What am I missing here?
Thank you

In your example you're echo'ing out multiple JSON strings because your output code is within a while loop. There should only be one output for the JSON string. The code below will give you a two dimensional array in JSON format.
$info = array();
while ($row = mysql_fetch_assoc($result))
{
$arr = array();
$arr["name"] = $row["name"];
$arr["country"] = $row["country"];
$info[] = $arr;
}
echo json_encode($info);
