PSR suggests, method names MUST be declared in camelCase and class names MUST be declared in StudlyCaps.

StudlyCaps, also known as PascalCase, implies that the first capital of each subword is capitalized. camelCase implies, like a camel, that the humps are in the middle, therefore the first letter is not capitalized.

Compare Microsoft's standards for .NET.

Other well known capitalization styles are snake_case, where all words are concatenated in lowercase with underscores, and kebab-case, which is identical but uses a hyphen.
