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($params);echo "params<pre>";print_r($params);echo "<hr>";$str = '';foreach ($params as $k => $v) {$str .= $k . $v;}return $str;}$param_json = array('name' => 'qipa250','url' => '','leader' => '奇葩天地网',);echo "<hr>";echo "param_json<pre>";print_r($param_json);echo "<hr>";$param_json_str = getSign($param_json);echo $param_json_str;echo "<hr>";
结果打印：
