PHP - Priting 8 Char Hex

Hi all

I am trying to loop through an array and output as JSON.
What I'm looking to do is create something like:

Code: [Select]
  "something": [
{"title":"Test 1"},
{"title":"Test 2"}
],

Notice that the final row has no comma.

My code is as follows:


<?php foreach($something as $thing): ?>
<?php $something_array = array('title'=>$thingt->getId()); ?>
<?php echo json_encode($something_array).','."\n"; ?>
<?php endforeach; ?>


I had to add a comma to the end of the array, or the JSON rows would not be ended with one.

How can I get it so that, no matter how many items are in the array, the last row, wil not have the comma at the end?

With the comma at the end, my JSON doesn't validate

Thanks

I have the following code:

Code: [Select]
$str = ($stringcontents[$step+38]);
$str1 = ord($str);
$bgcolor = convertchar($str1);
?>
<td bgcolor='<?php echo $bgcolor;?>'>
<span title='<?php echo $fieldname;?>' style='color: <?php echo $fgcolor;?>; font-size: 12pt'><font color="<?php echo $fgcolor;?>"><?php echo $stringcontents[$step];?></font></span>

the convertchar function takes the ord value of the ASCII chr and sets a variable for bgcolor and fgcolor using HTML color codes.  The background sets correctly, but the foreground ASCII chr is always black and does not use the font color code.

What do I need to do to get the ASCII chr to change to a color other than black?


Added:
I am using a default charset:

<META http-equiv="Content-Type" content="text/html; charset=IBM437">

I have a list of pictures and I want to control the order.


Here is the picture format:
$pic = http://www.picture.biz/incoming/w_2GTEK13T961240561_1.jpg
$pic = http://www.picture.biz/incoming/w_2GTEK13T961240561_2.jpg
$pic = http://www.picture.biz/incoming/w_2GTEK13T961240561_3.jpg
$pic = http://www.picture.biz/incoming/w_2GTEK13T961240561_4.jpg
$pic = http://www.picture.biz/incoming/w_2GTEK13T961240561_5.jpg

Notice the order 1.jpg, 2.jpg, etc..

Here is where I'm stuck...

// begin stuck :)
$orderPic = explode("_", $pic);

foreach($orderPic as $rank){
     echo "$rank"; // I need $rank to equal 1 then 2 then 3 ...
}


It would be nice actually if I could start the insert with number 2 because number one is always a screwy picture.

I hope this makes sense /  Thank for the help!

Code:

Code: [Select]
PostInfo,color-main,Newman,not-collapsed;Friends,color-main2,Top Friends,not-collapsed||Twitter,color-main2,Twitter,not-collapsed;Signature,color-main2,Signature,not-collapsed;AboutMe,color-transparent,About Me,not-collapsed

Now I want make a function like

if PostInfo = "not-collapsed" = do this/etc,


So simply, how do I extract some content out of this and then use each thing to equal to if it's 'not-collapsed' or 'collapsed' ?

Very hard but i think possible? ty
