What solution was suggested in the forum thread to ensure that only whole words are highlighted in PHP?

The issue is that the current solution is highlighting partial words in PHP. To ensure that only whole words are highlighted, one solution suggested in the forum thread is to use regular expressions to match whole words. This can be achieved by using the \b anchor to match word boundaries before and after the search term. 

// Example code snippet to highlight whole words in PHP
$searchTerm = "example";
$text = "This is an example of how to highlight whole words in PHP.";

// Use regular expression with \b anchor to match whole words
$highlightedText = preg_replace("/\b$searchTerm\b/i", "<strong>$0</strong>", $text);

echo $highlightedText;
