How can PHP tags be properly utilized to ensure the correct execution of code within a script?

To ensure the correct execution of code within a PHP script, it is important to properly utilize PHP tags. PHP code should always be enclosed within <?php ?> tags or <?= ?> tags for short echo statements. Failure to use these tags correctly can result in syntax errors or code not being executed as intended.

// Correctly utilizing PHP tags
echo &quot;Hello, world!&quot;;
