1.file_get_contents
$url = http://www.xxx.com/;
$contents = file_get_contents($url);
//如果出现中文乱码使用下面代码
//$getcontent = iconv("gb2312", "utf-8",file_get_contents($url));
//echo $getcontent;
echo $contents;
2.curl
$url = "http://www.xxx.com/"; $ch = curl_init(); $timeout = 5; curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout); //在需要用户检测的网页里需要增加下面两行 //curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_ANY); //curl_setopt($ch, CURLOPT_USERPWD, US_NAME.":".US_PWD); $contents = curl_exec($ch); curl_close($ch); echo $contents;
3.fopen->fread->fclose
$handle = fopen ("http://www.xxx.com/", "rb");
$contents = "";
do {
$data = fread($handle, 8192);
if (strlen($data) == 0) {
break;
}
$contents .= $data;
} while(true);
fclose ($handle);
echo $contents;
Ps
1.使用file_get_contents和fopen必须空间开启allow_url_fopen。方法：编辑php.ini，设置allow_url_fopen = On，allow_url_fopen关闭时fopen和file_get_contents都不能打开远程文件。
2.使用curl必须空间开启curl。方法：WIN下修改php.ini，将extension=php_curl.dll前面的分号去掉，而且需要拷贝ssleay32.dll和libeay32.dll到C:\WINDOWS\system32下；Linux下要安装curl扩展。
