simplifying a whole stack of codes in for loop

Is it possible in simplifying this stack of codes? They all have things in common but have differences as well:

$i=0;
if (!empty($keyword1))
	{
		echo "<span class='' id='' style='font-weight: bold; color: red;'> ".$keyword1."</span>\n";
		$i++;
	}
if (!empty($keyword2))
	{
	  if ($i > 0)
		{
			echo  " + ";
		}
		echo "<span class='' id='' style='font-weight: bold; color: blue;'> ".$keyword2."</span>\n";
	}
if (!empty($keyword3))
	{
	  if ($i > 0)
		{
			echo  " + ";
		}
		echo "<span class='' id='' style='font-weight: bold; color: blue;'> ".$keyword3."</span>\n";
			$i++;
	}
if (!empty($keyword4))
	{
	  if ($i > 0)
		{
			echo  " + ";
		}
		echo "<span class='' id='' style='font-weight: bold; color: green;'> ".$keyword4."</span>\n";
		$i++;
	}
if (!empty($keyword5))
	{
	  if ($i > 0)
		{
			echo  " + ";
		}
		echo "<span class='' id='' style='font-weight: bold; color: orange;'> ".$keyword5."</span>\n";
		$i++;
	}
if (!empty($keyword6))
	{
	  if ($i > 0)
		{
			echo  " + ";
		}
		echo "<span class='' id='' style='font-weight: bold; color: purple;'> ".$keyword6."</span>\n";
		$i++;
	}
if (!empty($keyword7))
	{
	  if ($i > 0)
		{
			echo  " + ";
		}
		echo "<span class='' id='' style='font-weight: bold; color: aqua;'> ".$keyword7."</span>\n";
		$i++;
	}						
if (!empty($keyword8))
	{
	  if ($i > 0)
		{
			echo  " + ";
		}
		echo "<span class='' id='' style='font-weight: bold; color: aqua;'> ".$keyword8."</span>\n";
		$i++;
	}
if ($_GET['book_spoke'] == 'Book_Spoke'){
	{
	  if ($i > 0)
		{
			echo  " AND ";
		}
		echo "<span class='' id='' style='font-weight: bold; color: black;'> in BOOK SPOKE ".$spoke."</span>\n";
		$i++;
	}	
}
if ($_GET['chapter_spoke'] == 'Chapter_Spoke'){
	{
	  if ($i > 0)
		{
			echo  " AND ";
		}
		echo "<span class='' id='' style='font-weight: bold; color: black;'> in CHAPTER SPOKE ".$spoke."</span>\n";
		$i++;
	}	
}
if ($_GET['verse_spoke'] == 'Verse_Spoke'){
	{
	  if ($i > 0)
		{
			echo  " AND ";
		}
		echo "<span class='' id='' style='font-weight: bold; color: black;'> in VERSE SPOKE ".$spoke."</span>\n";
		$i++;
	}	
}
echo '<br />';

PHP:

 

Basically you want to get all these keywords into an array and loop through it. Try something like:

$keywords = array();
$keywords[sizeof($keywords)] = $keyword1;
$keywords[sizeof($keywords)] = $keyword2;
$keywords[sizeof($keywords)] = $keyword3;
$keywords[sizeof($keywords)] = $keyword4;
$keywords[sizeof($keywords)] = $keyword5;
$keywords[sizeof($keywords)] = $keyword6;
$keywords[sizeof($keywords)] = $keyword7;
$keywords[sizeof($keywords)] = $keyword8;

$first_keyword = 1;

for ($i = 0;$i <= sizeof($keywords);$i++)
{
   if (!empty($keywords[$i]))
   {
      if ($first_keyword == 0)
         echo " + ";

      echo "<span class='' style='font-weight: bold; color: aqua;'> " . $keywords[$i] . "</span>\r\n";
      $first_keyword = 0;
   }
}

PHP:

Also note that doing id='' is a bad idea. Just leave id out or give each element a unique value. Also use "\r\n" instead of just "\r" or just "\n" - this way all users will get the carriage return.

$keywords[] > $keywords[sizeof($keywords)]
