Php 在fpdf中显示带有存储在数据库中的样式的html标记,php,mysql,fpdf,Php,Mysql,Fpdf,我将html数据存储在db表中，文本如下所示，通过html WYSIWYG编辑器设置样式 <ul> <li><span style="background-color:rgb(255, 255, 255); color:rgb(35, 64, 70); font-family:lucida grande,lucida sans unicode,helvetica,arial,verdana,sans-serif; font-size:13px">Sta

我将html数据存储在db表中，文本如下所示，通过html WYSIWYG编辑器设置样式

<ul>
    <li><span style="background-color:rgb(255, 255, 255); color:rgb(35, 64, 70); font-family:lucida grande,lucida sans unicode,helvetica,arial,verdana,sans-serif; font-size:13px">Static Website</span></li>
    <li><span style="background-color:rgb(255, 255, 255); color:rgb(35, 64, 70); font-family:lucida grande,lucida sans unicode,helvetica,arial,verdana,sans-serif; font-size:13px">Number of Pages-20</span></li></ul>
但在fpdf中，它是非常随意的，就像这样

<ul>
 <li><span

您的示例代码不太完整，但根据您现有的情况，您的主php文件可能如下所示
