用法一
<?php require 'querylist/vendor/autoload.php'; use QL\QueryList; $html = QueryList::run('DImage',[ //html内容 'content' => file_get_contents('http://xxx.com/1.html'), //图片保存路径(相对于网站跟目录),可选,默认:/images 'image_path' => '/xx/x/', //网站根目录全路径,如:/var/www/html 'www_root' => dirname(__FILE__), //补全HTML中的图片路径,可选,默认为空 'base_url' => 'http://uploads.rayli.com.cn', //图片链接所在的img属性,可选,默认src //多个值的时候用数组表示,越靠前的属性优先级越高 'attr' => array('data-src','src'), //单个值时可直接用字符串 //'attr' => 'data-src', //回调函数,用于对图片的额外处理,可选,参数为img的phpQuery对象 'callback' => function($imgObj){ $imgObj->attr('alt','xxx'); $imgObj->removeAttr('class'); //...... } ]); print_r($html);
用法二
$url = 'http://cms.querylist.cc/news/it/547.html'; $reg = [ 'title' => array('h1','text'), 'content' => array('.post_content','html') ]; $data = QueryList::Query($url,$reg,'.content')->getData(function($item){ //图片本地化 $item['content'] = QueryList::run('DImage',[ 'content' => $item['content'], 'image_path' => '/img/'.date('Y-m-d'), 'www_root' => dirname(__FILE__) ]); return $item; }); print_r($data);
用法三
