http://box1.host1free.com/~crimso/index.php  this link is my live test i have the xml set in the way i want it looking but i cant for the  life of me reverse and limit it

 

<?php
function getPage($url="http://www.treasuretrooper.com/api/116fcbdb1cac242e789a892ebd2a0abb/approved/xml"){
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL, $url);
curl_setopt($ch,CURLOPT_FRESH_CONNECT,TRUE);
curl_setopt($ch,CURLOPT_CONNECTTIMEOUT,5);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,TRUE);
curl_setopt($ch,CURLOPT_REFERER,'http://www.treasuretrooper.com/');
curl_setopt($ch,CURLOPT_TIMEOUT,10);
$xml=curl_exec($ch);
if($xml==false){
  $m=curl_error(($ch));
  error_log($m);
}
curl_close($ch);
return $xml;
}
$xml=getPage("http://www.treasuretrooper.com/api/116fcbdb1cac242e789a892ebd2a0abb/approved/xml");

echo $xml;

Reverse the feed? Does that mean displaying the same list, but backwards? Like this?

WML - Gas Card

Flash Forward

WS - Burger King

Also provide that code that you're using to display the feed. That's just the function to get the XML data.

yes  display the info the other way right now im just echoing  xml  ie the entire feed until i logic out a better way to handle this

Parse it into an array and use array_reverse

[dropfaith]

Okay So ive never had to build an array from an external source xml document So excuse this question.

I tried the code below

Got an array but as you can imagine the entire file flags as key 0.  Where as i need it to seperate the items  if i plot to limit and reverse its direction.

 

<?php
$xmlfile = getPage("http://www.treasuretrooper.com/api/116fcbdb1cac242e789a892ebd2a0abb/approved/xml");


$xmlf = array("$xmlfile");
print_r(array_reverse($xmlf));
foreach($xmlf as $Item => $Name) {
echo $Item . " " . $Name . "<br>";
}?>

Well no. I meant parse each XML entry into some array-type format. You'll want to look up a XML parser and get that done first. It's pretty easy if you Google PHP XML Parser.

ehh  other then reversing it im good now  i think im still way off on the direction i should have gone tho

 

<?php
function getPage($url="http://www.treasuretrooper.com/api/116fcbdb1cac242e789a892ebd2a0abb/approved/xml"){
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL, $url);
curl_setopt($ch,CURLOPT_FRESH_CONNECT,TRUE);
curl_setopt($ch,CURLOPT_CONNECTTIMEOUT,5);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,TRUE);
curl_setopt($ch,CURLOPT_REFERER,'http://www.treasuretrooper.com/');
curl_setopt($ch,CURLOPT_TIMEOUT,10);
$xml=curl_exec($ch);
if($xml==false){
  $m=curl_error(($ch));
  error_log($m);
}
curl_close($ch);
return $xml;
}


$xmlfile = getPage("http://www.treasuretrooper.com/api/116fcbdb1cac242e789a892ebd2a0abb/approved/xml");
$approved =new SimpleXMLElement($xmlfile);
$i = 0;
echo <<<EOF
<h2>Approving Now</h2>
<ul>
EOF;

foreach($approved as $approve) // loop through our Offers
{  		
	$i++;
        echo <<<EOF
        <li>{$result->Name}</li>
EOF;
if($i >= 15)
	break;
}
echo <<<EOF
</ul>
EOF;


?>

foreach (array_reverse($approved) as $approve)

Oh oops. Yeah, you are missing parts of code there. After you parsed the XML, loop through and store them into array instead of echo-ing it out. Then loop the array to print it out.

[dropfaith]

I wont lie i legit have no idea what your talking about on that lol.  Im pretty much teaching myself this as i go i dont use php  ever.. Started like last night ish

[Kays]

Okay no problem.

 

The point is that XML by itself can't be sorted the way you want. So you have to use another medium (like an array). It's more annoying than it is difficult.

 

1. Delete everything you have below $approved = new SimpleXMLElement($xmlfile);;

2. Create an array, let's say: $results = array();

3. Loop through $approved as you already had it: foreach ($approved as $approve)

4. Now for each $approve, store its data in $results. Preferably just the data you need, but to keep this simple, just add the whole $approve to $results as so: $results[] = $approve;

5. Finally, loop through the $results array, but in reverse order: foreach (array_reverse($results) as $result). Inside this for loop, you want put those echo statements that you had.

 

Does that help?
