I have a PHP script that's being called through jQuery AJAX. I want the PHP script to return the data in JSON format to the javascript. Here's the pseudo code in the PHP script:

$json = "{";
foreach($result as $addr)
{
    foreach($addr as $line)
    {
        $json .= $line . "\n";
    }
    $json .= "\n\n";
}
$json .= "}";

Basically, I need the results of the two for loops to be inserted in $json.
