Namespace in PascalCase
-
Rule: Each namespace MUST be declared in PascalCase (also known as UpperCamelCase).
-
Reason: PascalCase is the convention in PHP for namespaces, helping to differentiate them from variables and functions. It enhances consistency and readability in the codebase.
Example (Correct):
namespace MyProject;
namespace MyProject\SubNamespace;Example (Incorrect):
namespace myproject;
namespace myproject\subnamespace;
Top-Level Namespace
-
Rule: Each namespace MUST have a top-level namespace.
-
Reason: The top-level namespace serves as the root or primary namespace of your project, organizing all the other sub-namespaces under it.
Example (Correct):
namespace MyProject;
namespace MyProject\SubNamespace;
Example (Incorrect):
namespace;
namespace \SubNamespace;
Sub-Namespace
-
Rule: Each namespace SHOULD have at least one sub-namespace.
-
Reason: Sub-namespaces help organize different components or modules of the project, ensuring better structure and maintainability.
Example (Correct):
namespace MyProject\SubNamespace;Example (Incorrect):
namespace MyProject;
