Unable to iterate an array in a PHP foreach loop - php

Question

My request PHP file elaborates some Ajax POST data:
POST data
data[0][id]:359
data[0][position]:1
data[1][id]:321
data[1][position]:2
data[2][id]:354
data[2][position]:3
Request.php
if(isset($_POST['data'])) {
if(isset($_SESSION['username']) && isset($_SESSION['password'])) {
$verify = $loggedIn->verify();
if($verify['username']) {
$Profile = new Profile();
$Profile->db = $db;
//Call my function
$messages = $Profile->setOrder($_POST['data']);
}
}
}
Profile.php
function setOrder($post) {
var_dump($post);
foreach($post as $item)
{
return "Area ID ".$item["id"]." and person located ".$item["position"]."<br />";
}
}
My function returns nothing and the dump of $post is as below
array(3) {
[0]=>
array(2) {
["id"]=>
string(3) "359"
["position"]=>
string(1) "1"
}
[1]=>
array(2) {
["id"]=>
string(3) "321"
["position"]=>
string(1) "2"
}
[2]=>
array(2) {
["id"]=>
string(3) "354"
["position"]=>
string(1) "3"
}
}
Inside my function I can dump correctly something like var_dump($post[0]["id"]); so why my foreach loop is empty?

Answer 1

It is because you are using return inside loop. It will terminate the loop after first iteration. You need to do something like this.
$return = null;
foreach($data as $item)
{
$return .= "Area ID ".$item["id"]." and person located ".$item["position"]."<br />";
}
return $return;
