php正则匹配类
- 代码:
/** * @desc:正则匹配类 * @author [Lee] <[

/Ui */ class match{ private $content = ''; /* @desc:构造方法,初始化待匹配文本 */ public function __construct($content){ $this->content = $content; } /* @desc:获取所有超链接 @return:所有匹配的超链接 */ public function geturl(){ $content = $this->content; $preg = '/<[a|A].*?href=[\'\"]{0,1}([^>\'\"\ ]*).*?>/i'; $bool = preg_match_all($preg,$content,$res); $urls = array(); if($bool){ $urls = $res[1]; } return array_unique($urls); } /* @desc:获取所有图片 @return:所有匹配的图片 */ public function getimg(){ $content = $this->content; $preg="/(src)=(\\\?)([\"|']?)([^ \"'>]+\.(gif|jpg|jpeg|bmp|png|svg))\\2\\3/i"; $bool = preg_match_all($preg,$content,$res); $imgs = array(); if($bool){ $imgs = $res[4]; } return array_unique($imgs); } /* @desc:获取所有音频文件 @return:所有匹配的音频文件 */ public function getaudio(){ $content = $this->content; $preg="/(src)=(\\\?)([\"|']?)([^ \"'>]+\.(mp3|wav|wma|ogg|ape|acc))\\2\\3/i"; $bool = preg_match_all($preg,$content,$res); $audios = array(); if($bool){ $audios = $res[4]; } return array_unique($audios); } /* @desc:获取所有视频文件 @return:所有匹配的视频文件 */ public function getvideo(){ $content = $this->content; $preg="/(src)=(\\\?)([\"|']?)([^ \"'>]+\.(swf|flv|mp4|rmvb|avi|mpeg|ra|ram|mov|wmv)((\?[^ \"'>]+)?))\\2\\3/i"; $bool = preg_match_all($preg,$content,$res); $videos = array(); if($bool){ $videos = $res[4]; } return array_unique($videos); } /* @desc:获取所有段落文本 @return:所有匹配的段落文本 */ public function getparagraph(){ $content = $this->content; $preg="/

- 测试:
$match = new match($str); $ret = $match->getimg(); var_dump($ret);
- 输出:
array(7) { [0]=> string(61) "https://assets-cdn.github.com/images/search-shortcut-hint.svg" [1]=> string(69) "https://assets-cdn.github.com/images/spinners/octocat-spinner-128.gif" [2]=> string(75) "https://assets-cdn.github.com/images/spinners/octocat-spinner-32-EAF2F5.gif" [3]=> string(68) "https://assets-cdn.github.com/images/spinners/octocat-spinner-32.gif" [14]=> string(45) "https://badges.gitter.im/walkor/Workerman.svg" [15]=> string(48) "/upload/otherpic47/106945.jpg" [16]=> string(42) "http://donate.workerman.net/img/donate.png" }
