However, when using PHP functions in XSLT, many people encounter the following two errors:

(1) Warning: effectprocessor: transformToXml (): xmlXPathCompiledEval: 1 objects left o
N the stack.
(2) PHP Warning: effectprocessor: transformToXml (): xmlXPathCompOpEval: function func
Tion bound to undefined prefix php in ....

The code is as follows: Copy code

<? Php
$ Xml = <EOB
<Allusers>
<User>
<Uid> bob </uid>
</User>
<User>
<Uid> joe </uid>
</User>
</Allusers>
EOB;
$ Xsl = <EOB
<? Xml version = "1.0" encoding = "UTF-8"?>
<Xsl: stylesheetversion = "1.0"
Xmlns: xsl = "http://www.w3.org/1999/XSL/Transform">
<Xsl: output method = "html" encoding = "UTF-8" indent = "yes"/>
<Xsl: template match = "allusers">
<Html> <body>
<H2> Users <Table>
<Xsl: for-each select = "user">
<Tr> <td>
<Xsl: value-
Select = "php: function ('ucfirst', string (uid)"/>
</Td> </tr>
</Xsl: for-each>
</Table>
</Body> </Xsl: template>
</Xsl: stylesheet>
EOB;
$ Xmldoc = DOMDocument: loadXML ($ xml );
$ Export doc = DOMDocument: loadXML ($ xsl );
 
$ Proc = new effectprocessor ();
$ Proc-> registerPHPFunctions ();
$ Proc-> importStyleSheet ($ export Doc );
Echo $ proc-> transformToXML ($ xmldoc );
?>

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

The code is as follows: Copy code
<Xsl: stylesheetversion = "1.0"
Xmlns: xsl = "http://www.w3.org/1999/XSL/Transform">

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

The code is as follows: Copy code

<Xsl: stylesheetversion = "1.0"
Xmlns: xsl = "http://www.w3.org/1999/XSL/Transform"
Xmlns: php = "http://php.net/xsl">
