Basic pdo oop in php - php

Question

I'm new in php oop..I'm having trouble in showing my fields value. I have here the ff classes.
public static function getAll()
{
self::conn();
try
{
$sql = "SELECT * FROM dbo.guitar";
$q = self::$db->prepare($sql);
$q->execute();
$results = $q->fetchAll(PDO::FETCH_CLASS | PDO::FETCH_PROPS_LATE,
"Guitar",
array('id', 'make', 'model', 'colour', 'price'));
}
catch (Exception $e)
{
print "Error!: " . $e->getMessage();
}
return $results;
}
I want it to show from diff fields. Here is my code:
$guitars = Guitar::getAll();
I can see the values when I try using the print_r
What I want is like this.
echo $row['field1']; echo $row['field2'];
THank you in advance.

Answer 1

You are fetching result as objects, so you could do like this:
$guitars = Guitar::getAll();
foreach ($guitars as $guitar) {
echo $guitar->getId();
echo $guitar->getMake();
// ... and so on
}
Addtion:
You need to have the constructor to set the property, and provide public methods to access the property.
class Guitar {
private $id;
private $make;
private $model;
private $color;
private $price;
public function __construct($id, $make, $model, $color, $price) {
$this->id = $id;
$this->make = $make;
$this->model = $model;
$this->color = $color;
$this->price = $price;
}
public function getId() {
return $this->id;
}
public function getMake() {
return $this->make;
}
// and so on...
}
