Or if $v is supposed to count across all files:

$length = $xml.length();
for ($i = 0; $v < 10 && $i < $length; $i++) {
    $entry = $xml[$i];
    $v++;
    // Do stuff
}

>From reading that code it would seem you've got a series of XML files (the outer while loop) each containing an unknown number of entries (the foreach loop and counter), however I can't see $next being reset anywhere inside the loop, so IF you had less then 10 objects in the file it would run once and die when "$next == $last".

In you case with more then 10 entries it runs once over the first file and stops because it has more then 10. From the logic in your description however it sounds like you are wanting different then foreach on the inner loop.

Is this line:
"foreach ($xml as $entry)" where the real work occurs? I haven't even got a php runtime on this PC (and I've been writing java an python for week, so forgive stuff-ups) so I can't test but, I think you want pseudo-code something like:

$length = $xml.length();
for ($i = 0; i < 10 && $i < $length; $i++) {
    $entry = $xml[$i];
    // Do stuff
}

Hi Folks,

 

I’m trying to get a script to work in order to pull some vcard information from an xml document but have come up against a php quirk for which I can’t find a solution. I was wondering if anyone had any suggestions.

 

I am trying to get the script to finish after the first 10 “person” entries for testing but the while loop doesn’t appear to evaluate $v until the foreach loop which increments it is complete. The while loop is therefore actually stopping when $v = 100 as there are 100 entries per xml file;   

 

Here’s some of the code:

 

    $v = 0;

    $endloop = false;

 

while($endloop == false && $v < 10) {

 

        $xml = simplexml_load_file($next);

               

                    if($xml && $next != $last) {

                    

                    foreach ($xml->link as $link) {

                        $attributes = $link->attributes();

                        if($attributes->rel == "next") {

                            $last = $attributes->href;

                        }   

                    }

 

                    foreach ($xml as $entry) {

                        $id = (string)$entry->id;

                        $vparse = new Contact_Vcard_Parse();

                        $cardinfo = $vparse->fromText($entry->content);

               

                        $persons[$v] = array('id' => $id,

                                                               'firstname' => ucfirst(strtolower($cardinfo['0']['N'][0]['value']['given'][0])),

                                                               'lastname' => ucfirst(strtolower($cardinfo['0']['N'][0]['value']['family'][0])));

                               

                        $v++;

                                   

                    }

 

                }

 

                else {

               

                    $endloop = true;

               

                }

            }

 

Cheers,
