For HTML ypu pass it through HTML validator: validator.w3.org/

For JavaScript you use FireBug (or similar tool for browser other than FF)

For PHP... there are many tools and options, depending on what your coding style is. The very basic is an IDE with syntax error detection (like NetBeans), and using some sensible form of error handling (that include error logging)
