cURL doesn't seem to work in a while loop
Question
I'll just post the whole thing since it would be a bit confusing otherwise:
<?php
echo "<html>
<head>
<title>ARMORY.</title>
<meta http-equiv='Content-Type' content='text/html' charset=iso-8859-1>
</head>
<body>
<table width='50%' border='1' cellpadding='10' cellspacing='10'>";
$server = "Sunstrider";
$guild = "Mist";
$url='http://eu.wowarmory.com/guild-info.xml?r='.$server.'&gn='.$guild.'&p=1';
$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt ($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.1) Gecko/20061204 Firefox/2.0.0.1");
$xml = curl_exec($ch);
$rosterxml = new SimpleXMLElement($xml);
curl_close($ch);
$array = array();
foreach($rosterxml->guildInfo->guild->members->character as $char)
if(strtolower($char['level']) === '80')
{
$array[] = $char['name']."<br />";
}
echo "
<tr>
<td valign='middle'>Name</td>
<td valign='middle'>TEST</td>
</tr>";
$i = 0;
while($array[$i] != null)
{
$name = $array[$i];
$raidurl='http://eu.wowarmory.com/character-achievements.xml?r='.$server.'&cn='.$name.'&c=168';
$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL, $raidurl);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt ($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.1) Gecko/20061204 Firefox/2.0.0.1");
$xml2 = curl_exec($ch);
$achievementxml = new SimpleXMLElement($xml2);
curl_close($ch);
var_dump($achievement);
echo "<tr>
<td>$array[$i]</td>
<td></td>
</tr>";
$i++;
}
?>
</body>
</html>
That var_dump of $achievement just produces NULL over and over again (obviously due to the loop) instead of any information about the array. Doing a var_dump of $rosterxml produces the expected effect though, so cURL seems to work fine outside of the while loop.

That is because your variable is called $achievementxml and not $achievement .
I would advise you to code with error_reporting=E_ALL so you can catch errors like this. Undefined variables will result in an E_NOTICE level error message.
