请教 $this->root->_[HDOM_INFO_END] 是什么意思
在 学习 simple_html_dom 源码的时候。
发现里面的语法有这样的 $this->root->_[HDOM_INFO_END] = $this->cursor; 

新人求高人指教,这个什么意思。。。谢谢。

------解决方案--------------------
$this->root 是一个 simple_html_dom_node 对象(在 917 行处实例化的)
$this->root->_ 是 simple_html_dom_node 的一个属性(在 115 行处定义的)

整句就是赋值.
具体负的什么值,作用是什么?要由上下文来决定
断章取义的不行的
