In the past two months, WeChat marketing has been spreading like crazy. I have been paying attention to this new thing. Gradually, I have some opinions. I 'd like to share it with you today.


I first paid attention to "Wang Lihong". I told him a sentence, and he quickly returned a long speech. then I did not talk about it. From the very beginning, I knew that this must have been done by machines. out of curiosity, I talked to him from time to time and did not reply much. It was also the kind of things that I could say to anyone. One day, he suddenly received a WeChat message from Wang Li Hong, which said about his concert in Jiaxing. I think this is also recorded in the WeChat platform.

Idea: put the data into the $ ContentBox variable after processing the data. if $ ContentBox-> nodeValue is directly output, the webpage and source code are displayed normally, but the html tag (such as p src) and the image is gone. if you copy $ ContentBox to another dom, the webpage is displayed normally, but the source code text is similar to ascii (the labels and images are not lost ), as follows,

$Target = new DOMDocument;
        $Target->appendChild($Target->importNode($ContentBox, true));

echo $Target->saveHTML();

What is the reason? how can this problem be solved?

------ Solution --------------------
$ Target = new DOMDocument ('1. 0 ', 'utf-8'); $ ContentBox = $ Target-> importNode ($ ContentBox, true); echo $ Target-> saveXML ($ ContentBox );
