用法一 ​

php
<?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);
<?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__),

    '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

	//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);

 '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__)
