Save results from pdo query to a javascript variable

Question

I am new to javascript so please be patient with me. I have a function in php which goes like this:

 public function getSubjects() {
            $stmt = $this-&g         


        

Answer 1

I like to use json_encode to convert the array to json so it can be used as an array of objects in JS.

PHP:

public function getSubjects() {
    $stmt = $this->_db->prepare('SELECT id, subject from subjects');
    $stmt->execute();                     
    return json_encode($stmt->fetchall());
}

In javascript:

var subs = ;
console.log(subs);
