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

<?php
require 'querylist/vendor/autoload.php';
use QL\QueryList;

$con =<<<STR
<img src="/App/Tpl/Home/images/loading.gif"  data-original="/images/896891/c21alNoWfSAJ6xqN44SRAdW+0M3gZ7H3msPj8/SpdYZXnUZprQ1Xg5IxQcARLus6wz9xz5O7xve82KY2dpmEGjuLP49w.jpg" alt="鲑鱼龙虾鱼子酱" class="img-responsive img-thumbnail lazy">
<br/>
<img src="/App/Tpl/Home/images/loading.gif">
STR;

$html = QueryList::run('DImage',[
        'content' => $con,
        'www_root' => dirname(__FILE__),
        'base_url' => 'http://x.44i.cc',
        'attr' => array('data-original','src'),
        'image_path' => '/xx',
        'callback' => function($o){
            $o->attr('alt','111');
            $o->removeAttr('class');
        }
    ]);
echo $html;
/**
输出:
