Ok, so I am not as dumb as I thought I was That is what I was trying to do but all my post was displaying is the code and NOT the actual message in rainbow text. Hmm I wonder

Nice shoot Highway of Life!

I did code something similar for me a while ago...

Here is the code to obtain a gradiented text, starting from a color, ending into another... even with random color capabilities.

Spoiler:

Code: Select all

function gradient($text, $color1, $color2, $mode = 'random', $iterations = 10)
{
   //
   // Returns text highlighted in random gradient colours
   //
   if ($mode == 'random')
   {
      $colors = load_random_colors();
   }
   else
   {
      $colors = load_gradient_colors($color1, $color2, $iterations);
   }
   $text = trim(stripslashes($text));
   $length = strlen($text);
   $result = '';
   $color_counter = 0;
   $TAG_OPEN = false;
   for ( $i = 0; $i < $length; $i++ )
   {
      $char = substr($text, $i, 1);
      if ( !$TAG_OPEN )
      {
         if ( $char == '<' )
         {
            $TAG_OPEN = true;
            $result .= $char;
         }
         elseif ( preg_match("#\S#i", $char) )
         {
            $color_counter++;
            $result .= '<span style="color: ' . $colors[$color_counter] . ';">' . $char . '</span>';
            $color_counter = ( $color_counter == $iterations ) ? 0 : $color_counter;
         }
         else
         {
            $result .= $char;
         }
      }
      else
      {
         if ( $char == '>' )
         {
            $TAG_OPEN = false;
         }
         $result .= $char;
      }
   }
   return $result;
}

function rand_color()
{
   $color_code = mt_rand(0, 255);
   if ($color_code < 16)
   {
      return ('0' . dechex($color_code));
   }
   else
   {
      return dechex($color_code);
   }
}

function load_random_colors($iterations = 10)
{
   $random_color = array();
   for ( $i = 0; $i < $iterations; $i++ )
   {
      $random_color[$i + 1] = '#' . rand_color() . rand_color() . rand_color();
   }
   return $random_color;
}

function load_gradient_colors($color1, $color2, $iterations = 10)
{
   $col1_array = array();
   $col2_array = array();
   $col_dif_array = array();
   $gradient_color = array();
   $col1_array[0] = hexdec(substr($color1, 1, 2));
   $col1_array[1] = hexdec(substr($color1, 3, 2));
   $col1_array[2] = hexdec(substr($color1, 5, 2));
   $col2_array[0] = hexdec(substr($color2, 1, 2));
   $col2_array[1] = hexdec(substr($color2, 3, 2));
   $col2_array[2] = hexdec(substr($color2, 5, 2));
   $col_dif_array[0] = ($col2_array[0] - $col1_array[0]) / ($iterations - 1);
   $col_dif_array[1] = ($col2_array[1] - $col1_array[1]) / ($iterations - 1);
   $col_dif_array[2] = ($col2_array[2] - $col1_array[2]) / ($iterations - 1);
   for ( $i = 0; $i < $iterations; $i++ )
   {
      $part1 = round($col1_array[0] + ($col_dif_array[0] * $i));
      $part2 = round($col1_array[1] + ($col_dif_array[1] * $i));
      $part3 = round($col1_array[2] + ($col_dif_array[2] * $i));
      $part1 = ($part1 < 16) ? ('0' . dechex($part1)) : (dechex($part1));
      $part2 = ($part2 < 16) ? ('0' . dechex($part2)) : (dechex($part2));
      $part3 = ($part3 < 16) ? ('0' . dechex($part3)) : (dechex($part3));
      $gradient_color[$i + 1] = '#' . $part1 . $part2 . $part3;
   }

   return $gradient_color;
}

I still don't know how this is done

[Sniper_E]

I've seen how he does it.... but I want tell.

[Highway of Life]

I've seen how he does it.... but I want tell.

Now the test will be to see if you can reproduce.

I found This Gradient text generator but I am wondering...Is there a way to make a custom bbcode for this?

Are we talking about copy and paste? That would be the only way I could reproduce anything.

[stitch626]

Haaa, In your face! I think I got it but would lis to covert it to a custom bbcode.

[Highway of Life]

Innerface, huh? well! very nice! very nice indeed. But can you beat this!!?
