**一.curl資源遷移curl對象** #php8開始curl資源也無縫遷移到curl對象   **二.查看類型** ``` $curl = curl_init(); ```   **三.curl獲取數據** 1.get.php ``` $arr=[ 'user1'=>'123', 'user2'=>'456', 'user3'=>'789', ]; echo json_encode($arr); ``` 2.index.php ``` $url='http://bbs.linux.com/get.php'; //生成curl對象 $curl = curl_init(); //設置url curl_setopt($curl, CURLOPT_URL, $url); //curl_exec是返回獲取值 curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); //獲取并返回 echo curl_exec($curl); ```   **四.hosts域名解析** #/etc/hosts ``` 127.0.0.1 bbs.linux.com ```   **五.curl發送post數據** 1.get.php #直接返回curl過來的post數據 ``` echo json_encode($_POST); ``` #模擬登錄 ``` if($_POST['user1']=='222'){ echo '{"login":"yes"}'; }else{ echo '{"login":"no"}'; } ``` 2.index.php ``` $url='http://bbs.linux.com/get.php'; $curlPost=[ 'user1'=>'222', 'user2'=>'555', 'user3'=>'999', ]; //生成curl對象 $curl = curl_init(); //設置url curl_setopt($curl, CURLOPT_URL, $url); //curl_exec是返回獲取值 curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); //設置post請求 curl_setopt($curl, CURLOPT_POST, 1); //發送post數據 curl_setopt($curl, CURLOPT_POSTFIELDS, $curlPost); //獲取并返回 echo curl_exec($curl); ```
