PHP编程：PHP中使用socket方式GET、POST数据实例

<?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)<br />n";
? return false;
?}
?else
?{
???? $out = "GET $path HTTP/1.1rn";
???? $out .= "Host: $hostrn";
???? $out .= "Connection: Closernrn";
? $ret = "";
???? fwrite($fp,$out);
???? while (!feof($fp))
? {
???????? $ret .= fgets($fp,128);
???? }
???? fclose($fp);
?}
?return true;
}
?>

<?php
function socketPost($url,$data,30);
?if (!$fp)
?{
???? echo "$errstr ($errno)<br />n";
? return false;
?}
?else
?{
???? $out = "POST $path HTTP/1.1rn";
???? $out .= "Host: $hostrn";
? $out .= "Content-Type: application/x-www-form-urlencodedrn";
? $out .= "Content-Length: ".strlen($data)."rn";
???? $out .= "Connection: Keep-Alivernrn";
? $out .= $data;
? $ret = "";
???? fwrite($fp,128);
???? }
???? fclose($fp);
?}
?return true;
}
?>
