How can whitespace and line breaks impact the parsing of PHP code, and what tools can be used to identify and correct such issues?

Whitespace and line breaks can impact the parsing of PHP code by causing syntax errors or unexpected behavior. To identify and correct such issues, developers can use code formatting tools like PHP Code Beautifier and Fixer (php-cs-fixer) or IDEs with built-in code formatting features.

// Example of using PHP Code Beautifier and Fixer to format PHP code
// Install php-cs-fixer globally using Composer: composer global require friendsofphp/php-cs-fixer
// Run php-cs-fixer on a PHP file to fix formatting issues: php-cs-fixer fix your-file.php
