i have a current script that does this but if you have text before the quoting it eats it and throws it into a quote.

function kill_nesting($string)
{
      $s_array = explode('[quote]',$string);
      $nu_string = '';
      $nesting = 0;
      if(sizeof($s_array) > 1)
      {
            foreach($s_array as $key => $value)
            {
                  $ss_array = explode('[/quote]',$value);
                  if(sizeof($ss_array) > 1 && $nesting) // Capture Last
                  {
                        $nu_string .= $ss_array[(sizeof($ss_array)-2)].'[/quote]'.$ss_array[(sizeof($ss_array)-1)]; // Collect Last Element Which Holds 1st Quote
                        $nesting = 0;
                  }
                  else if($nesting == 1) // Dump Nested Material
                  {
                        ;
                  }
                  else // Capture First
                  {
                        if($value != '')
                        {
                              $nu_string .= '[quote]'.$s_array[$key];
                              $nesting = 1;
                        }
                  }
            }
      }
      else
      {
            $nu_string = $string;
      }
      unset($ss_array);
      unset($s_array);
      return $nu_string;

just change this line
$nu_string .= '[quote]'.$s_array[$key];
to
$nu_string .= $s_array[$key].'[quote]';

chrisnetonlineAuthor Commented:
now if there isnt text before the quote it takes some of the text from the quote and spits it above the quote box

armoghanCommented:
ohh got the problem,
its the explode('[quote]',$string);
which forgets that there was text before quote or not
You need to have a check in
// Capture First
block to see if the $string starts with quote or not .

I hope you get it .
If you want i can give you code for it

armoghanCommented:
check this piece of code in if condition

      if($value != '')
      {
      $value1 = strpos($string, '[quote]');
      if( $value1 == 0 )
      {
            $nu_string .= '[quote]'.$s_array[$key];
      }
      else
      {
            $nu_string .= '[quote]'.$s_array[$key].$s_array[$key+1];
      }
      $nesting = 1;

hello!
according to your question this function could help you:

<?php
function remNes($str)
{
      $ar = explode('[/quote]', $str);
      if (count($ar > 2))
      {
            return('[quote]' . $ar[count($ar) - 2] . '[/quote]');
      }
      return $str;
}

however it messes up if there are more than one set of "main" quotes like below.

The current code outputs the below:
Test [quote]Inside First outside test [/quote]Last new before new inside [/quote] new after [quote]

How I need it to be outputed:
Test [quote]Inside First outside test [/quote]Last  new before [quote]new inside[/quote]  new after

armoghanCommented:
hmm ,
It would be very difficult to go with the same algorithm and solve the problem you stated in the last comment as explode('[quote]',$string); removes the quote and do not remember the any quotes in between.
To do such a task probably some other algorithm is required
0
 
armoghanCommented:
In the initial requirement there was nothing about nested quotes.. Which was introduced afterwards.. So initial requirement was fulfilled..
The nesting requires soime another algorithum and cannot be done by the same code

So would claim points for this post
