What are the potential challenges of using str_replace to modify links in an included HTML file in PHP?

One potential challenge of using str_replace to modify links in an included HTML file in PHP is that it may not handle all variations of links (e.g., links with query parameters or anchors) correctly. To overcome this challenge, you can use regular expressions to search and replace links in the HTML content, which provides more flexibility and accuracy in modifying links. 

<?php
// Read the contents of the included HTML file
$html_content = file_get_contents('included_file.html');

// Use regular expressions to search and replace links in the HTML content
$html_content = preg_replace('/<a href="(.+?)">/', '<a href="new_link">', $html_content);

// Output the modified HTML content
echo $html_content;
?>
