Escaping <? on php shorthand enabled server when using require

What I want is that when I make a Ajax get request to domain/xml.php. It return a XML file, so I can use httpRequest.responseXML to parse the XML file.

what I did is:

<?php
    $name = 'Just a tester';
?>

<?xml version='1.0' ?>
<name><?php echo $name ?></name>

But the parser gives me an error of the line <?xml version='1.0' ?>, I thought it might be syntax conflict with the php delimiter <?php.

How can I request a url and get xml generated by php?

Answer 1

Why are you trying to embed PHP variables into XML instead of generating the XML with PHP?

Example (xml.php):

<?php 
header('Content-type: text/xml; charset=utf-8');

//Your Data
$persons = array(array('name'=>'bob','age'=>20,'sex'=>'M'),
                 array('name'=>'steve','age'=>26,'sex'=>'M'),
                 array('name'=>'jen','age'=>33,'sex'=>'F'),
                 );


$xml = new SimpleXMLElement('<?xml version="1.0" encoding="UTF-8"?><persons/>');

foreach ($persons as $person) {
    $node = $xml->addChild('person');
    foreach($person as $key=>$value){
        $node->addChild($key, $value);
    }
}
//DOMDocument to format code output
$dom = new DOMDocument('1.0');
$dom->preserveWhiteSpace = false;
$dom->formatOutput = true;
$dom->loadXML($xml->asXML());

echo $dom->saveXML();

/* OUTPUT
<?xml version="1.0" encoding="UTF-8"?>
<persons>
  <person>
    <name>bob</name>
    <age>20</age>
    <sex>M</sex>
  </person>
  <person>
    <name>steve</name>
    <age>26</age>
    <sex>M</sex>
  </person>
  <person>
    <name>jen</name>
    <age>33</age>
    <sex>F</sex>
  </person>
</persons>
