What tools or techniques can be used to streamline the process of updating PHP code for newer versions?

Updating PHP code for newer versions can be streamlined by using tools like PHPCompatibility to check for deprecated functions and syntax, using automated testing tools like PHPUnit to ensure code compatibility, and utilizing version control systems like Git to track changes and roll back if needed. Additionally, refactoring code to adhere to current best practices and standards can help make updates smoother. 

// Example PHP code snippet using PHPCompatibility to check for deprecated functions
require_once 'PHPCompatibility/PHPCSHelper.php';
$phpcsFile = 'path/to/your/file.php';
$phpcs = new PHP_CodeSniffer();
$phpcs->registerSniffs(array('PHPCompatibility'), array(), array());
$phpcs->processFile($phpcsFile);
