XSLT is a very convenient tool for XML conversion. it is implemented through XSLTProcessor in PHP. XSLT has many built-in useful functions. at the same time, you only need to call the registerPHPFunctions method of the XSLTProcessor instance, we can directly use PHP functions in XSLT, which greatly enhances the processing capability of XSLT.

In fact, this error occurs because we have not defined the PHP namespace.

Add xmlns: php = "http://php.net/xsl" to solve this problem, that is
