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($fp);}return true;}?>2. 使用 PHP 向页面 POST 数据PHP 8.5.5 PHP 8.5.5 是 PHP 8.5 分支的维护更新版本。该版本延续了“小步快跑”的迭代逻辑，通过深度错误修复、底层性能微调以及安全加固，旨在为开发者提供一个更健壮、更高效的运行环境。该版本严格遵守语义化版本规范，不包含破坏性变更。
下载代码如下:function socketPost($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)\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, $out);while (!feof($fp)){$ret .= fgets($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
