JQuery Autocomplete不能使用PHP

Question

Hi does anyone have any ideas why my JQuery autocomplete is not bringing back any results?

Here is the PHP code:

$result = mysql_query("SELECT * FROM stations where StationName like '%" .     mysql_real_escape_string($_GET['term']) . "%'");

$array = array();

while($row = mysql_fetch_array($result, MYSQL_ASSOC)) {

 $row_array[] = $row['StationName'];
 array_push($array, $row_array);
}

echo json_encode($array);

Here is the JS code:

$(function() {

$('#location').val("");

$("#location").autocomplete({

    source: "autocomplete.php",
    minLength: 2,
    select: function(event, ui) {
        $("#location").val(ui.item.location);
    }

 });
});

And finally the HTML:

<input type='text' class="suggest" id='location'>
