PHP variable in HTML without form

Question

I have two pages 1st Html and 2nd PHP where I am treating some XML data returned after reading an XML file, but I have a question, I need to take a value that I take from XML and put inside an html tag, I’ve done like this and nothing

the PHP page is being called in HMTL(its extension and .php) by require_once.

SNIPPET OF HTML

HOW TO CALL A PHP VARIABLE VALUE IN HTML TAG ?

Answer 1

With a simple ECHO :

test.xml :

<?xml version="1.0" encoding="UTF-8"?>
<Nfe>
    <dados>
        <cliente>fulano</cliente>
        <cnpj>1234</cnpj>
    </dados>
</Nfe>

test php.

<?
$xmldata = simplexml_load_file("test.xml") or die("Failed to load");

$cnpj = $xmldata->dados[0]->cnpj;
$cliente = $xmldata->dados[0]->cliente;
?>


<h2> <? echo $cnpj; ?> </h2>
<h2> <? echo $cliente; ?> </h2>
