    hi all, ive been trying to get a facebook feed to display on a website.

    the php is sound, or so i think....

    but its throwing up two red flags
    <html>
 <head>
  <title>PHP Test</title>
 </head>
 <body>
<?php
//Get the contents of the Facebook page
$FBpage = file_get_contents('https://graph.facebook.com/PAGE_ID/feed?access_token=ACCESS_TOKEN');
//Interpret data with JSON
$FBdata = json_decode($FBpage);
//Loop through data for each news item
foreach ($FBdata->data as $news )
{
//Explode News and Page ID's into 2 values
$StatusID = explode("_", $news->id);
echo '<li>'
//Check for empty status (for example on shared link only)
if (!empty($news->message)) { echo $news->message;}
echo '</li>'
}
?>
 </body>
</html>

    the lines that are off are:

    if (!empty($news->message)) { echo $news->message;}

    and the last }

    any help greatly appreciated.

    You're missing some semicolons there.

    Add them on to the two lines:

    [PHP]
    echo '<li>';
    echo '</li>';
    [/PHP]

    Probably have to set something for ACCESS_TOKEN too, not sure where you'll find it though, haven't used facebook much.

    thank you, i already have the access token from facebook.

    when the corrected code is inserted into my php page.

    it returnd the following output, which is just part of the code. the php is within a div
    <div style="position: absolute; top: 247px; left: 269px; width: 509px; height: 674px; z-index: 64; background-color: #333333; layer-background-color: #333333; border: 1px none #000000;" id="element440">
        
  <?php
//Get the contents of the Facebook page
$FBpage = file_get_contents('https://graph.facebook.com/xxxxxxxxx/feed?access_token=xxxxxxxx');
//Interpret data with JSON
$FBdata = json_decode($FBpage);
//Loop through data for each news item
foreach ($FBdata->data as $news )
{
//Explode News and Page ID's into 2 values
$StatusID = explode("_", $news->id);
echo '<li>';
//Check for empty status (for example on shared link only)
if (!empty($news->message)) { echo $news->message;}
echo '</li>';
}
?>
        
        </div>

    and the output:
    data as $news ) { //Explode News and Page ID's into 2 values $StatusID = explode("_", $news->id); echo '
'; //Check for empty status (for example on shared link only) if (!empty($news->message)) { echo $news->message;} echo '
'; } ?>

    im not a complete noob, but php has me puzzled...

    That shouldn't be happening at all with the code you posted.
    There's something wrong further up the line.
    The output is starting after:
    foreach ($FBdata->
    The closing angle bracket looks like it's closing off an open tag somewhere.
    I was able to recreate this problem output by attempting using PHP "short tags" (which I have turned off) <? ?> rather than the normal form of <?php ?>
    Go through your code and make sure every bit of php you're using is opened with <?php

    Check the bleedin' obvious... as well as the <?php ?> tags mentioned above, make sure your webserver is parsing the file. Usually this means the filename must end in '.php'.

    Also I guess you are relying on your code editor to tell you where the PHP errors are. It is much better to keep an eye on your error log - you'll get more information that way.
