使用php的ksort函数对数组排序生成sign签名的方法

function getSign($params)
{
    unset($params['sign']);
    ksort($params);

    echo "params
";
    print_r($params);
    echo "
";
    $str = '';
    foreach ($params as $k => $v) {
        $str .= $k . $v;
    }

    return $str;
}


$param_json = array(
    'name' => 'qipa250',
    'url' => 'www.qipa250.com',
    'leader' => '奇葩天地网',
);

echo "
";
echo "param_json
";
print_r($param_json);

echo "
";
$param_json_str = getSign($param_json);
echo $param_json_str;
echo "
";

 
  
结果打印：
