PHP中使用socket方式GET、POST数据实例
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
