[PHP] Help translating PHP5 code to PHP4.

[Marc Guay]

Hi folks,

I've stumbled into a project involving a server running PHP4 without
cURL.  The script fetches data from an XML webservice and deals with
it.  Is http://ca2.php.net/xml_parser_create the place to start?  Any
tips (besides updating PHP)?

Here's an example of the PHP5 code:

$url = "http://www.domain.com/webservice.php?var=foo";;                  
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$val = curl_exec($ch);
curl_close($ch);
libxml_use_internal_errors(true);
$xml = simplexml_load_string($val);
$errors = libxml_get_errors();

if (!($errors)){
        $myvariable = $xml->attributes()->value;
}
else{
        // deal with errors     
}
