PHP擴充之XML操作（四）－XMLReader

一、概述與安裝

一、概述及安裝

The XMLReader extension is an XML Pull parser. The reader acts as a cursor going forward on the document at pum stop the stop. note that internally, libxml uses the UTF-8 encoding and as such, the encoding of the retrieved contents will always be in UTF-8 encoding.

此擴充需要 libxml PHP 擴充。這表示需要使用 

--enable-libxml

 ，儘管這將隱式完成因為 libxml 是缺省開啟的。

The XMLReader extension was initially a PECL extension for PHP 5. It was later moved to the PHP source (bundled) as of PHP 5.1.0, and later enabled by default as of PHP 5.1.2.35.1.2.此擴充認為啟用,編譯時可透過下列選項停用： --disable-xmlreader
