How can the repeated opening and closing of PHP tags affect the performance of a PHP script?

Repeated opening and closing of PHP tags can affect the performance of a PHP script by causing unnecessary parsing of the PHP code. To improve performance, it is recommended to minimize the number of PHP tags in a script by using a single set of opening and closing tags. 

<?php

// Bad practice with repeated opening and closing PHP tags
?>
<html>
<?php
echo "Hello, World!";
?>
</html>
<?php

// Better practice with a single set of opening and closing PHP tags
?>
<html>
<?php
echo "Hello, World!";
?>
</html>
