Use logical and descriptive names for your variables. Variables used in iterating loops, such as $i, $j, $k, etc., are exceptions to this rule. Variables should contain only lower-case letters, underscores, and numbers, and should start with a letter. Values true, false, and null should always be lower-case.

$foo = 365; // not descriptive
$days_in_non_leap_year = 365; // too long
$_year_days = 365; // starts with an underscore
