In my experience, the full underscores (SOME_CONST) is a popular convention for constants in many languages including Java, PHP and Python. Updat When a name is highly localized, lacks business context or used within a few lines of code, it may be acceptable to use a short name (fi rather than CustAcctFileInfo). When a project is written in multiple languages, it's not possible to have a single naming convention. For each language, adopt the naming convention prevalent in that language

The method name contains a verb get.It would not make much sense to name the method simply absoluteDifference(), because such name does not indicate any action.. The same rule applies to increase() method. Its name also contains a verb increase, which expresses what action it performs.
  2. g conventions for code released by PHP FIG. Interfaces MUST be suffixed by Interface: e.g. Psr\Foo\BarInterface. Abstract classes MUST be prefixed by Abstract: e.g. Psr\Foo\AbstractBar. Traits MUST be suffixed by Trait: e.g. Psr\Foo\BarTrait. PSR-1, 2 and 4 MUST be followed. The vendor namespace MUST be Psr.

For example, the $ in PHP and Shell. punctuation.definition.variable; Immutable variables, often via a const modifier, should receive the following scope. Depending on the language and semantics, entity.name.constant may be a better choice

You basically prefixed every variable name with a code denoting the data type that variable contained. This resulted in variable names like strName (a string) or u32Number (a 32-bit unsigned integer)
