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">

'base_url' => 'http://x.44i.cc',
'attr' => array('data-original','src'),
'image_path' => '/xx',
'callback' => function($o){
$o->attr('alt','111');
