从DOMPDF获取错误"foo“

Question

我有一个生成多个报告的脚本，每个报告都是使用DOMPDF转换成pdf的。报告的大小和内容类型各不相同，但通常混合了图像、表格和样式化文本。

在我试图转换的最新报告中，我得到了以下错误：

#23 index.php(150): Zend_Application->run()
#24 {main}  

我通过验证器运行输入到DOMPDF的html，没有出现错误或警告。该报告确实包括几个表，但这些表都不会被强制拆分到多个页面上(最长的表大约是一页的三分之一)。除了无效的HTML之外，我不确定是什么导致了这一问题，搜索这个错误只表明这是一个潜在的原因。

有什么建议吗？

我读了这篇文章，然后开始挖掘https://groups.google.com/forum/?fromgroups#!topic/dompdf/yXDoankutY8的错误。

检查您的CSS和HTML是否都有效。我使用Tidy函数修复了我的HTML，删除了CSS，一点一点地重新实现它。

在我的例子中，它是一个简单的CSS规则：

.views-row {
  display: block;
}
