PHP CodeSniffer, aka phpcs, helps you in detecting violations in your PHP code. Violations can be:
- opening curly brackets in the wrong place (on a new line, or vice versa)
- indentation
- use of upper- or lowercase variable/function/method/class names
- missing phpdoc blocks for files, classes or functions
- your own coding standards
- etc.
Before installing PHP CodeSniffer with PEAR, you actually need to install PEAR.
Installing PHP CodeSniffer is as simple as:
$ sudo pear install PHP_CodeSniffer
Check out the manual for more information: http://pear.php.net/manual/en/package.php.php-codesniffer.php
