Insert data to array using while loop php - php

Question

I am trying to insert data from database into an array, using while loop, here is my database:
id resulst
152556 0
152555 1
152553 1
152552 0
152551 1
152550 0
152549 1
Here is the code that I did:
$output = [
"online" => 0,
"success" => 0,
"servers" => []
];
$mini_result = $db->query("SELECT * FROM `sessions` WHERE status = '1' LIMIT 5");
while( $result = $mini_result->fetch()){
$output['servers']['mini_result'] = [
$result['id'] => $result['result']
];
}
$output["online"] = 1;
$output["success"] = 1;
echo json_encode($output, JSON_PRETTY_PRINT );
Output:
{
online: 1,
success: 1,
servers: {
mini_result: {
152556: "0"
}
}
}
It only prints 1 element, not 5 as I would like. This is the output I want:
{
online: 1,
success: 1,
servers: {
mini_result: {
152556: "0",
152555: "1",
152553: "1",
152552: "0",
152551: "1"
}
}
}
Can you help me?

Answer 1

You overwrite the result on every loop of the loop. What you need to do is:
while($result = $mini_result->fetch()) {
$output['servers']['mini_result'][$result['id']] = $result['result'];
}
This does get quickly quite confusing. You can simplify it, like this:
$miniResult = [];
while($result = $mini_result->fetch()) {
$miniResult[$result['id']] = $result['result'];
}
$output['servers']['mini_result'] = $miniResult;

This what u need:
$mini_result = $db->query("SELECT * FROM `sessions` WHERE status = '1' LIMIT 5");
$output['servers']['mini_result'] = [];
while( $result = $mini_result->fetch()){
$output['servers']['mini_result'][$result['id']] = $result['result'];
}
