如何获取PHP脚本以将数据提供给JQuery自动完成？

Question

我现在有以下数据提供JQuery Autocomplete

 var network_autocomplete=[
                "ActionScript",
                "AppleScript",
                "Asp",
                "BASIC",
                "C",
                "C++",
                "Clojure",
                "COBOL",
                "ColdFusion",
                "Erlang",
                "Fortran",
                "Groovy",
                "Haskell",
                "Java",
                "JavaScript",
                "Lisp",
                "Perl",
                "PHP",
                "Python",
                "Ruby",
                "Scala",
                "Scheme"
            ];

            $( "#network" ).autocomplete({
                source: network_autocomplete
            });

我需要修改它以从php页面检索结果数组.有人可以帮我修改这个,所以我可以在JavaScript中这样做吗？

network_autocomplete=data

目前,代码以这种方式从SQLite表中检索数据:

try {
    $db = new PDO('sqlite:/tmp/bacnet.db');
    $query = "SELECT net, name,  FROM network";

    foreach ($db->query($query) as $row) {
        $networks[] = array('net' => $row['net']);
    }

    echo json_encode($networks);
    return json_encode($networks);
} catch (PDOException $e) {
    echo json_encode(array('message' => 'Could not connect to the database'));
}

更改$networks[] = array('net' => $row['net']);为
$networks[] = $row['net']; 并且您不应该返回，除非这是一个函数（如果它是一个函数，为什么它有一个回声？）
