PHP数组到json可读输出

Question

我有一个 php 数组

if(mysql_affected_rows() > 0)
{
    $status = "OK";

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

        $info[] = array( 
                'postDate' => $row[1],
                'vedioURL' => extractifrem($row[2]),
                'like' => $row[3],  
                'totalView' => $row[4], 
                'viewTime' => $row[5]                   
            );

    }

$output = array(
            'status' => $status,
            'result' => $info
        );

我想将 $output 的结果打印为有效的 json 可读。我正在使用此代码但无法正常工作

$soutput = array();
foreach($output as $v) {
    $soutput[key($v)] = current($v);
}
echo json_encode($soutput, 128);

像这样..

$soutput = array();
foreach($output as $k=>$v) {
    $soutput[$k] = $v;
}
echo json_encode($soutput);
