php json_encode奇怪问题说明

复制代码 代码如下:

$array = array (
[0] => array ( [sale_unit_detail_id] => 13 [price] => 740000 [geometric_lat] => 51.50348620 [geometric_lng] =>-0.01710900 )
[1] => Array ( [sale_unit_detail_id] => 27 [price] => 740000 [geometric_lat] => 51.50348620 [geometric_lng] => -0.01710900 )
);

复制代码 代码如下:

$menu[0][0] = "title1";
$menu[0][1] = "bar1";
$menu[0][2] = "bar2";
$menu[1][0] = 'title2';
$menu[2][0] = 'title3';
echo '&$menu='.json_encode($menu).'&';

复制代码 代码如下:

$menu[0]["title"] = "title1";
$menu[0]["bar1"] = "bar1";
$menu[0]["bar2"] = "bar2";
$menu[1][0] = 'title2';
$menu[2][0] = 'title3';
echo '&$menu='.json_encode($menu).'&';
