php wrap specific word in text string with html tags

This is a small function to wrap a specific word in a text string with a html tag. So lets say I want to wrap the third word in

<b></b>

tags I would use below.

echo WrapWord('This is my line of text!', '3', 'b');

Above would output "This is my line of text!" you will need the function for above to work otherwise it will most likely display a blank page, The function WrapWord(); is below.

function WrapWord($text, $position, $tag) {
   $ex = explode(' ', $text);
   foreach ($ex as $key => $val) {
      if ($key == $position-1) {
         $val = "<${tag}>${val}</${tag}>";
      }
      $word_string .= "${val} ";
   }
      return $word_string;
}
 

some other examples below.

echo WrapWord('This is my line of text!', '4', 'i');
//Outputs "This is my <i>line</i> of text!"

echo WrapWord('This is my line of text!', '2', 'p');
//Outputs "This <p>is</p> my line of text!"

echo WrapWord('This is my line of text!', '1', 'span');
//Outputs "<span>This</span> is my line of text!"
 

and a full mark up of the php file.

<?php
function WrapWord($text, $position, $tag) {
   $ex = explode(' ', $text);
   foreach ($ex as $key => $val) {
      if ($key == $position-1) {
         $val = "<${tag}>${val}</${tag}>";
      }
      $word_string .= "${val} ";
   }
      return $word_string;
}


echo WrapWord('This is my line of text!', '3', 'b');
?>
