How can PHP code be properly escaped within a string to prevent it from being interpreted as the closing tag?

To prevent PHP code within a string from being interpreted as the closing tag, you can use the backslash (\) character to escape the closing tag sequence (?>). This tells PHP to treat the closing tag as a literal character rather than the end of PHP code execution. By properly escaping the closing tag, you can ensure that the PHP code within the string is not executed prematurely.

echo 'This is a string with PHP code: <?php echo "Hello, World!"; ?> To prevent the closing tag from being interpreted, escape it like this: \?>';
