php读写标签 [英] php write and read tags

问题描述

我想用DOMDocument解析器将标记写入.txt文件并读取它们，但是有时最后我得到的是`& lt而不是`<`和`& gt`而不是`>`

我有某种渲染方式取决于`<`和`>`，因此，当更改为`& lt``和`& gt;`时，它不匹配.但是在项目的其他部分，一切都很好(书写，阅读，渲染).

写

I want to write tags into .txt file with DOMDocument parser and read them but sometimes at the end I get `&lt;` instead of `<` and `&gt;` instead of `>`

I have sort of rendering depends on `<`and `>` so when the change into `&lt;` and `&gt;` it doesn''t match. but in a different part of the project everything is fine (writing, reading, rendering).

write

$fh = fopen($fn, 'wb');   $str = $this->saveXML($node);  fwrite($fh, $str );  fclose($fh);

其中$ fn是一个字符串，用于保存文件路径，而$ node是我正在浏览的树中的当前节点

where $fn is a string the holds the file path and the $node is the current node in the tree I''m navigating through
read

$fh = fopen($fn, 'rb');  $str = fread($fh, filesize($fn)); 
$renderer->doc .= $renderer->_xmlEntities($str);

样本输入

sample input
