Question

PHP/CSS find word in string, change its color for display. Having a problem, can’t find its solution, any suggestions? thanks.

      <pre>

      <?php 
      $str="Try to realize the truth... there is no spoon."; // spoon can be anywhere in string
      $array = explode(" ", $str);
for($i=0;$i < count($array);$i++)
     {
       if ($array[$i] == "spoon") {
             ?><span style="color:red;"><?php echo echo $array[$i]." "; ?></span>
             <?php
           } else {
              echo $array[$i]." ";
           }   
     } ?>

      </pre

I would personally use:

function highlight($text='', $word='')
{
  if(strlen($text) > 0 && strlen($word) > 0)
  {
    return (str_ireplace($word, "<span class='hilight'>{$word}</span>", $text));
  }
   return ($text);
}

$str="Try to realize the truth... there is no spoon."; // spoon can be anywhere in string
$str= highlight($str, 'spoon');

Note: str_ireplace is the Case-insensitive version str_replace.

Also… obviously you will need to define the css for ‘hilight’ somewhere!
