Answer 1

Could you try this..

<?php
   $phrase  = "There are hundreds of mobiles in android.";
   $keywords = array("mobiles", "android");
   $replacement = array("<b>MOBILES</b>", "<b>ANDROID</b>");
   $newphrase = str_replace($keywords, $replacement, $phrase);

   echo $newphrase;
?>

EDIT:

I am working on your code, so the solution above can fit to your code.

So assuming that $row['desc'] is the phrase then it would be like this:

<?php
   $phrase  = $row['desc'];
   $keywords = array("mobiles", "android"); // or you could do the following
   $keywords = explode(" ", $this->input->post('keywords'); // Or whatever value it is from POST

   $replacement = array("<b>MOBILES</b>", "<b>ANDROID</b>"); // I over simplify things here.
   $newphrase = str_replace($keywords, $replacement, $phrase);

   echo $newphrase;
?>
