Returning an Object In a PHP Class - php

Question

I want to make a the following thing happen in PHP PDO OOP
$conn = mysqli_connect("localhost", "root", "blogger.g", "test");
$query = mysqli_query($conn, "SELECT * FROM users WHERE username='sandeep'");
$row = mysqli_fetch_assoc($query);
echo $row['password'];
The code which I use in the OOP way is as follows
class getResults{
public $results;
public function start(){
try {
$DTH = new PDO("mysql:host=127.0.0.1;dbname=test", "root", "blogger.g");
$STH = $DTH->query("SELECT * FROM users WHERE username='sandeep'");
$results = $STH->fetchAll(PDO::FETCH_OBJ);
return $results;
} catch (PDOException $e){
return $e->getMessage();
}
}
}
var_dump(getResults::start());
I got the following output
array(1) { [0]=> object(stdClass)#3 (3) { ["id"]=> string(1) "1" ["username"]=> string(7) "sandeep" ["password"]=> string(8) "password" } }
And How Should I access each of the properties ??

Answer 1

You can access each row if you loop through the object with a while()-loop, for example.
while($row = getResults::start()) {
echo $row->id;
}
One last tip: If you're already using PDO, use Prepared Statements. For your safety.

Answer 2

Since your query yields a single row, don't use fetchAll:
$results = $STH->fetch(PDO::FETCH_OBJ);
would suffice. Now, store the returned value inside a variable:
$x = getResults::start();
Since, $x is a class object, you can access its members by -> operator:
echo $x->username . "\n" . $x->password;
Alternatively, you can use PDO::FETCH_ASSOC:
$results = $STH->fetch(PDO::FETCH_ASSOC);
$x = getResults::start();
echo $x['username'] . "\n" . $x['password'];
