本文实例总结了php跨服务器访问方法。分享给大家供大家参考。具体分析如下:
近来项目中遇到跨服务器访问的问题,研究了好些日子,总结如下:
1、用file_get_contents方法
$host = 'url'; $randomNumber=file_get_contents($host); echo $$randomNumber;
2、用Curl
$host = 'url'; $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $host); // 返回结果 curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_HEADER, 0); // 使用POST提交 curl_setopt($ch, CURLOPT_POST, 1); // POST参数 $str = array('a=1','b=2','c=3'); curl_setopt($ch, CURLOPT_POSTFIELDS, $str); // 结果 $res = curl_exec($ch); curl_close($ch);
使用curl库,使用curl库之前,,你可能需要查看一下php.ini,查看是否已经打开了curl扩展
3、 用fopen打开url, 以get方式获取内容
希望本文所述对大家的php程序设计有所帮助。
