How can PHP be used to search for a specific word in a text and highlight it?

To search for a specific word in a text and highlight it using PHP, you can use the `str_replace` function to replace the word with an HTML tag that applies styling for highlighting. You can use a combination of PHP and HTML to achieve this, by searching for the word in the text and replacing it with the highlighted version. 

<?php
$text = "This is a sample text where we want to highlight a specific word.";
$word_to_highlight = "highlight";

$highlighted_text = str_replace($word_to_highlight, "<span style='background-color: yellow;'>".$word_to_highlight."</span>", $text);

echo $highlighted_text;
?>
