PHP, not display all inside my array, but only first resulting - php

Question

$projects = array('1' => $link1, '2' => $link2);
function server_status($projects) {
foreach ($projects as $server) {
$api_status = ping_api($server);
if ($api_status == 1) {
$json = json_decode(file_get_contents($server), true);
foreach ($json as $obj) {
if ($obj['online'] < 1) {
// OFFLINE
return -1;
}
else {
// ONLINE
return $obj['online'];
}
}
} else {
// MAINTENANCE
return 0;
}
}
}
function cache_status($data) {
echo $data;
$servername = "localhost";
$username = "root";
$password = "";
try {
$conn = new PDO("mysql:host=$servername;dbname=test", $username, $password);
// set the PDO error mode to exception
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
}
catch(PDOException $e)
{
echo "Connection failed: " . $e->getMessage();
}
foreach ($data as $status) {
// server id + status
$sql = "UPDATE projects SET status=:status WHERE id=:server_id";
$stmt = $conn->prepare($sql);
$stmt->bindParam(':status', $status, PDO::PARAM_INT);
$stmt->bindParam(':server_id', 1, PDO::PARAM_INT);
$stmt->execute();
}
}
$problem = array(server_status($projects));
print_r($problem);
My problem is, when I print_r the variable $problem it should return two results in array, since there are two results but it only returning the first result from array as an .. example: Array ( [0] => 260 )
IF anyone is kind enough to look at my code and tell me what I am doing wrong, I would be very greatful

You are using return statement inside your loop that is why it breaks your loop on first iteration and returns what ever you have mentioned to the original call of function. To resolve this issue you need to collect the response from each iteration in array and in the end of function return your response for each iteration something like
function server_status($projects) {
$response= array();
$status = 0; // default status
foreach ($projects as $server) {
$api_status = ping_api($server);
if ($api_status == 1) {
$json = json_decode(file_get_contents($server), true);
foreach ($json as $obj) {
if ($obj['online'] < 1) {
// OFFLINE
$status= -1;
}
else {
// ONLINE
$status = $obj['online'];
}
}
}
$response[] = array('server'=>$server,'status'=>$status);
}
return $response;
}
