#11760 — $dom->loadHTMLFile() error

I wrote a small block of code for a mate that parses another web page and 
it displays selected results from a table there. It runs fine locally using 
php 5.3. I'm not sure what version of php is in use on his web server, but
it appears that "<?php ... $dom->" is being parsed as a single tag in the 
following code:

----------BEGIN code----------------------
<?php

// Get the node_id from what was passed to this page.
if (isset($_GET['node_id'])) {
  $node_id = $_GET['node_id'];
} else {
  echo "No IRLP node number stated\n";
  break 3;
}

// Get the node status HTML code.
$url = "http://status.irlp.net/?nodeid=$node_id" ;
$dom = new DOMDocument;
$dom->loadHTMLFile("$url");
$links = $dom->getElementsByTagName('td');
foreach($links as $i){
  $node_status[] = $i->textContent;
}

// Print the fields of interest. Comment undesired lines such as:
//echo "<b>$node_status[40]</b> $node_status[41]<br>";
echo "<b>$node_status[40]</b> $node_status[41]<br>";
echo "<b>$node_status[42]</b> $node_status[43]<br>";
echo "<b>$node_status[44]</b> $node_status[45]";

?>
----------END code----------------------

On my php5.3, it returns (e.g. sans bold):

Local node date/time 14:39:10 on Nov 07 2013 CST
Current Node Status: IDLE for 0 days, 1 hours, 43 minutes, 7 seconds.
Last heard from Node: 12:56:02 on Nov 07 2013 CST

On his http://stn3717.ip.irlp.net:15426/get_node_status.php?node_id=3717

loadHTMLFile("$url"); $links = $dom->getElementsByTagName('td'); 
foreach($links as $i){ $node_status[] = $i->textContent; } 
// Print the fields of interest. Comment undesired lines such as: 
//echo "$node_status[40] $node_status[41]"; 
echo "$node_status[40] $node_status[41]"; 
echo "$node_status[42] $node_status[43]"; 
echo "$node_status[44] $node_status[45]"; ?> 

Is it possible that php isn't operational on that site, or that it
needs to be enabled on a per-user basis?

Sure it's possible PHP isn't installed.  Did you ask whomever is in 
charge of the server?

What do you see when you display the page source in the browser?  Do you 
see the <?php tag, for instance?

Just open
<http://stn3717.ip.irlp.net:15426/get_node_status.php?node_id=3717> in a
browser - then you will see it as well ;-)

I know I can open it.  But telling him that it isn't installed doesn't 
help him learn anything.

I prefer to teach a person to fish; you just give him the fish.

It's obvious that PHP is not being executed. Ask the site administrator
if this can be changed.

Thanks Arno, the site administrator reported some missing dependencies; 
all is working properly now.
