PHP_CodeSniffer is a script that tokenizes PHP, JavaScript and CSS files to detect violations of a defined coding standard - an essential development tool that ensures your code remains clean and consistent.

Common standards that can be checked include:

• Use of camel case in variable, function, class names
• Indentation rules, such as using tabs vs. spaces
• Forbidden functions, such as die()
• Checking that PHP files are side-effect-free
