This article is to share with you the content of a sample analysis of XMLReader for PHP extensions. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

I. Overview and installation

The XMLReader extension is an XML Pull parser. The reader acts as a cursor going forward on the document stream and stopping at each node on the way.

It is important to 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.

This extension requires a libxml PHP extension. This means that you need to use-- enable-libxml, although this will be done implicitly because libxml is enabled by default.

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.

This extension is enabled by default and can be disabled at compile time with the following options:-- disable-xmlreader
