I want to iterate through a list of strings and when it ends I want to start from the beginning. The first thing that comes to mind is circular linked lists. Through after very meticulous research (a quick google search ), I have not found any pre-made circular linked list class. Is there something in PHP 5 that encompasses this?

I am not quite sure what you want but would this work?

PHP Code:

$num = count($array);
$i = 0;

while ($i < $num)
{
   echo $array[$i];

   $i++;

   if ($i == ($num - 1))
       $i = 0;
} 

Not tested, my php skills are very rusty.

Here's another way ...

PHP Code:

$bDone=false;

$aBuffer=$aArray;

while (!$bDone)  

  foreach ($aBuffer as $k => $v)

  {

    // test for $bDone

    if ($bDone) break;

  }

Well, see the thing is, I don't want to reset the array (like physically go back)...

I am just wondering if there is something like a circular linked list in php?

You can use PHP references as pointers, but I don't think it would be worth the effort.

May I ask why? and what's the difference or drawbacks of resetting array's index if does the job easily?

Well, I ended up doing that. It wasn't worth the trouble to do it the other way.
