PHP bind_result and fetch multiple rows (array) - php

Question

I'm fairly new to php and mysql. I'm trying to create a rest api from php, and because my server doesn't have mysqlndinstalled, I have to use bind_result and fetch.
$stmt = $this->conn->prepare("SELECT * from d WHERE d.id = ?");
$stmt->bind_param("i", 1);
if($stmt->execute()){
$stmt->bind_result($a, $b, $c);
$detail = array();
while($stmt->fetch()){
$detail["a"] = $a;
$detail["b"] = $b;
$detail["c"] = $c;
}
$stmt->close();
return $response;
} else {
return NULL;
}
Above code works but it can only return 1 line of information at a time.
For example if the statement return:
a b c
1 test test
1 test1 test1
it only returns
a: 1
b: test1
c: test1
where its supposed to be:
{
a: 1
b: test
c: test
},
{
a: 1
b: test1
c: test1
}

You're overwritting them, you could do something like this instead:
$detail = array();
while($stmt->fetch())
{
$temp = array():
$temp["a"] = $a;
$temp["b"] = $b;
$temp["c"] = $c;
$detail[] = $temp;
}
Or directly appending them with another dimension:
$detail = array();
while($stmt->fetch()) {
$detail[] = array('a' => $a, 'b' => $b, 'c' => $c);
// ^ add another dimension
}
