1. 許多年前的代碼突然拿來一用，特做此筆記(此處的code用來定位內部錯誤位置,非http code)

1. <?php

3. function curl_url($url,$type=0,$timeout=30){
5. $msg = [‘code‘=>2100,‘status‘=>‘error‘,‘msg‘=>‘未知錯誤！‘];
6. $imgs= [‘image/jpeg‘=>‘jpeg‘,
7. ‘image/jpg‘=>‘jpg‘,

10. ‘text/html‘=>‘html‘,
11. ‘text/plain‘=>‘txt‘,
12. ‘image/pjpeg‘=>‘jpg‘,
