1. 使用 PHP 获得网页内容 GET方式
代码如下:
PHP
function socketGet($url,&$ret)
{
$urlArr = parse_url($url);
$host = $urlArr['host'];
$port = isset($urlArr['port'])?$urlArr['port']:80;
$path = isset($urlArr['path'])?$urlArr['path']:"/";
$fp = fsockopen($host,$port,$errno,$errstr,30);
if (!$fp)
{
echo "$errstr ($errno)
\n"; return false; } else { $out = "GET $path HTTP/1.1\r\n"; $out .= "Host: $host\r\n"; $out .= "Connection: Close\r\n\r\n"; $ret = ""; fwrite($fp,$out); while (!feof($fp)) { $ret .= fgets($fp,128); } fclose($fp); } return true; } ?>
\n"; return false; } else { $out = "GET $path HTTP/1.1\r\n"; $out .= "Host: $host\r\n"; $out .= "Connection: Close\r\n\r\n"; $ret = ""; fwrite($fp,$out); while (!feof($fp)) { $ret .= fgets($fp,128); } fclose($fp); } return true; } ?>
2. 使用 PHP 向页面 POST 数据
代码如下:
PHP
function socketPost($url,$data,30);
if (!$fp)
{
echo "$errstr ($errno)
\n"; return false; } else { $out = "POST $path HTTP/1.1\r\n"; $out .= "Host: $host\r\n"; $out .= "Content-Type: application/x-www-form-urlencoded\r\n"; $out .= "Content-Length: ".strlen($data)."\r\n"; $out .= "Connection: Keep-Alive\r\n\r\n"; $out .= $data; $ret = ""; fwrite($fp,128); } fclose($fp); } return true; } ?>
如果post报错，把$out .= "Connection: Keep-Alive\r\n\r\n";中的Keep-Alive改成Close
\n"; return false; } else { $out = "POST $path HTTP/1.1\r\n"; $out .= "Host: $host\r\n"; $out .= "Content-Type: application/x-www-form-urlencoded\r\n"; $out .= "Content-Length: ".strlen($data)."\r\n"; $out .= "Connection: Keep-Alive\r\n\r\n"; $out .= $data; $ret = ""; fwrite($fp,128); } fclose($fp); } return true; } ?>
