What is libxml extension?

PHP v. 5.3.8

 

What is libxml extension and how would I know if it's enabled?

 

My book told me

Note To take advantage of SimpleXML, make sure PHP's libxml extension is enabled.

libxml is a library that a bunch of extensions (such as SimpleXML) depend on. So if libxml is not installed, those extensions won't work.

 

Both libxml and SimpleXML are included by default with modern PHP versions, and must be explicitly disabled. You should be pretty safe to rely on them. Any shared host worth a damn will have them enabled, and they are easy enough to switch on in a VPS/dedi environment.

 

You can check for them, and any other PHP extension, by running this:

<?php phpinfo(): ?>

it says LIBxml support is active but I get

Warning: simplexml_load_file() [function.simplexml-load-file]: I/O warning : failed to load external entity "world.xml" in C:\xampp\htdocs\segovia\load\songs.php on line 8

bool(false)

 

this is the xml

<?xml version="1.0" encoding="utf-8"?>
<world>
<continents>
<NorthAmerica>
<country>US</country>
<country>Mexico</country>
<country>Canada</country>
</NorthAmerica>
<SouthAmerica>
<country>Equidor</country>
<country>Peru</country>
<country>Argentina</country>
</SouthAmerica>
</continents>
</world>

 

and this is my code:

<?php 
$xml = simplexml_load_file("world.xml");

var_dump($xml);
?>

[scootstah]

Does "world.xml" exist in the same directory as that script?

[attaboy]

yes it is

[scootstah]

What do these give you?

var_dump(file_exists('world.xml'), is_readable('world.xml'));

[attaboy]

on the other hand no it wasn't.

thanks scootstah!!

I managed to screw up a site in Dreamweaver  I had 2 identical directory's in different places I totally faked myself out.
