获取人的脸部特征信息，得到一组特征数组
第一步，在百度开发者中心申请人脸识别接口，具体步骤查询百度
第二步，申请成功后记下API Key和Secret Key
第三步，在框架/Library/Org/Util/目录下建立Baidu.class.php代码如下<?php /********************************************************** *Author: dtnet(presdecoeur@gmail.com) *Time: 2014-6-5下午5:35:13 *File: Bdauth.class.php **********************************************************/ namespace Org\Util; class Baidu { public static $BD_OAUTH2_ENDPOINTS = array ( 'authorize' => 'https://openapi.baidu.com/oauth/2.0/authorize', 'token' => 'https://openapi.baidu.com/oauth/2.0/token', 'logout' => 'https://openapi.baidu.com/connect/2.0/logout', 'face'=>'https://openapi.baidu.com/rest/2.0/media/v1/face/detect' ); protected $clientId; protected $clientSecret; protected $redirectUri; public function __construct($clientId, $clientSecret) { $this->clientId = $clientId; $this->clientSecret = $clientSecret; } public function setRedirectUri($redirectUri) { if (empty ( $redirectUri )) { $redirectUri = $this->getCurrentUrl (); } $this->redirectUri = $redirectUri; return $this; } public function getRedirectUri() { return $this->redirectUri; } public function getLogoutUrl($accessToken, $next = '') { $params = array ('access_token' => $accessToken,'next' => $next ? $next : $this->getCurrentUrl () ); return self::$BD_OAUTH2_ENDPOINTS ['logout'] .

':' . $parts['port'] : ''; // rebuild return $protocol . $parts['host'] . $port . $parts['path'] . $query; } private static function shouldRetainParam($param) { foreach (self::$DROP_QUERY_PARAMS as $drop_query_param) { if (strpos($param, $drop_query_param . '=') === 0) { return false; } } return true; } /** * Build the multipart body for file uploaded request. * @param array $params Parameters for the request * @return string */ private static function buildHttpMultipartBody($params) { $body = ''; $pairs = array(); self::$boundary = $boundary = md5('BAIDU-PHP-SDK-V2' . microtime(true)); foreach ($params as $key => $value) { if ($value{0} == '@') { $url = ltrim($value, '@'); $content = file_get_contents($url); $array = explode('?', basename($url)); $filename = $array[0]; $body .= '--' . $boundary . "\r\n"; $body .= 'Content-Disposition: form-data; name="' . $key . '"; filename="' . $filename . '"'. "\r\n"; $body .= 'Content-Type: ' . self::detectMimeType($url) . "\r\n\r\n"; $body .= $content .

'--'; return $body; } /** * Tries to detect MIME type of a file * * The method will try to use fileinfo extension if it is available, * deprecated mime_content_type() function in the other case.

'application/octet-stream': $info; } }第四步，在Common目录添加方法代码如下function face($url){ $clientId = '这里用API Key替换'; $clientSecret = '这里用Secret Key替换'; $image = new \Org\Util\Baidu($clientId,$clientSecret); return $image->getAccessFace($url); }第五步，使用函数
$url='http://xxx.xxx.com/xxx/xxx.jpg';
dump(face($url));
成功返回：

mPDF

mPDF は、UTF-8 でエンコードされた HTML から PDF ファイルを生成できる PHP ライブラリです。オリジナルの作者である Ian Back は、Web サイトから「オンザフライ」で PDF ファイルを出力し、さまざまな言語を処理するために mPDF を作成しました。 HTML2FPDF などのオリジナルのスクリプトよりも遅く、Unicode フォントを使用すると生成されるファイルが大きくなりますが、CSS スタイルなどをサポートし、多くの機能強化が施されています。 RTL (アラビア語とヘブライ語) や CJK (中国語、日本語、韓国語) を含むほぼすべての言語をサポートします。ネストされたブロックレベル要素 (P、DIV など) をサポートします。
