$content = '<p><img src="/uploads/image/20200818/1597720891186314.png" 
title="1597720891186314.png" alt="score1.png"/></p><p><video class="edui-upload-video  vjs-default-skin video-js" controls="" preload="none" width="420" height="280" src="/uploads/video/20200818/1597720911477773.mp4" data-setup="{}"></video></p>';print_r($content);echo '<br/>';echo "======================之前===================";echo '<br/>'; $t = new transFormation();$result = $t->transFormationContentImgSrc($content,'http://sxkj.cn');print_r($result);exit();/**
