PHP中使用socket方式GET、POST数据实例

2024-04-02 16:57:03 464

1.使用PHP获得网页内容GET方式


<?php

functionsocketGet($url,&$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";

 returnfalse;

 }

 else

 {

    $out="GET$pathHTTP/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);

 }

 returntrue;

}

?>

2.使用PHP向页面POST数据


<?php

functionsocketPost($url,$data,&$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";

 returnfalse;

 }

 else

 {

    $out="POST$pathHTTP/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($fp,$out);

    while(!feof($fp))

 {

        $ret.=fgets($fp,128);

    }

    fclose($fp);

 }

 returntrue;

}

?>

如果post报错，把$out.="Connection:Keep-Alive\r\n\r\n";中的Keep-Alive改成Close
