php怎么获取http状态
在项目开发中,有时我们需要知道远程的URL地址是否能访问正常,判断其正常与否后进行下一步的操作,那么在PHP中如何获取远程HTTP的状态呢?
逐风整理了两种方式,大家可以自行参考/使用:
#方式一 $ch = curl_init('http://www.scutephp.com'); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_exec($ch); echo curl_getinfo($ch, CURLINFO_HTTP_CODE); // 200 curl_close($ch);
#方式二 print_r( get_headers('http://www.baidu.com') ); #返回以下内容: /* Array ( [0] => HTTP/1.1 200 OK [1] => Date: Sun, 04 May 2014 03:43:04 GMT [2] => Content-Type: text/html; charset=utf-8 [3] => Connection: Close [4] => Vary: Accept-Encoding [5] => Set-Cookie: BAIDUID=4977AF4FB1E9A5D13C79939E28D92161:FG=1; expires=Thu, 31-Dec-37 23:55:55 GMT; max-age=2147483647; path=/; domain=.baidu.com [6] => Set-Cookie: BDSVRTM=0; path=/ [7] => Set-Cookie: H_PS_PSSID=4681_1465_5224_6023_4759_6018_6257_6313_6328_6269; path=/; domain=.baidu.com [8] => P3P: CP=" OTI DSP COR IVA OUR IND COM " [9] => Cache-Control: private [10] => Expires: Sun, 04 May 2014 03:42:09 GMT [11] => X-Powered-By: HPHP [12] => Server: BWS/1.1 [13] => BDPAGETYPE: 1 [14] => BDQID: 0x9acb602d00001922 [15] => BDUSERID: 0 ) */
