Returning JSON from a PHP Script

Question

I want to return JSON from a PHP script.

Do I just echo the result? Do I have to set the Content-Type header?

Answer 1

If you query a database and need the result set in JSON format it can be done like this:

fetch_array()){
    $rows[] = $row;
}
//Return result to jTable
$qryResult = array();
$qryResult['logs'] = $rows;
echo json_encode($qryResult);

mysqli_close($db);

?>

For help in parsing the result using jQuery take a look at this tutorial.
