Foreach PHP Loop into Array - abstract-data-type

Question

I am trying to create an array containing results from an SQL table. But my foreach loop does not appear to be function correctly.
Here is my code:
$stmt->bind_param("i", $id);
$stmt->execute();
while ($stmt->fetch()) {
}
$stmt->close();
$i = 0;
foreach ($connected_items as &$value) {
print_r ($connected_items[$i]);
$stmt->bind_param("i", $connected_items[$i]);
$stmt->execute();
while ($stmt->fetch()) {
$result[] = array(,
);
}
$stmt->close();
$i++;
}
unset($value);
)
)
It appears to be running the for loop on my print statement and then MySQL statement, using the last connected_items_id, why is that? And why is it not returning the associated values for that id?

Answer 1

remove this [] at line number 6:
while ($stmt->fetch()) {
$connected_items = array($connected_items_id);
}
instead of this:
while ($stmt->fetch()) {
$connected_items[] = array($connected_items_id);
}

Answer 2

Try this,
"connected_item_id" => $connected_items[0],
instead of
"connected_item_id" => $connected_items_id,

Answer 3

Try
foreach ($connected_items as $value) {
......................
......................
$stmt = $this->db->prepare('SELECT name, serial FROM `glpi_monitors` WHERE id =?');
$stmt->bind_param("i", $value[0]);
................................
................................
}
Also you can use IN keyword instead of looping and querying each time.
$sql = "SELECT name, serial FROM `glpi_monitors` WHERE id IN('".implode("','",$connected_items)."'");
$stmt = $this->db->prepare($sql);
