Best practices: 1. Use namespaces and aliases to reduce redundancy. 2. Use optional parameters to increase flexibility. 3. Perform parameter type checking to enhance robustness. Anti-patterns: 1. Abuse of aliases and duplicate namespaces. 2. Lack of type checking reduces reliability.
use
statement to reduce the complete namespace of function calls and improve code readability and maintainability. use App\Classes\MyClass; MyClass::myMethod();
as
keyword to create function aliases to simplify long function names and reduce code redundancy. function fullFunctionName() { // ... } $fn = 'fullFunctionName' as; $fn();
function myFunction($param1, $param2 = 'default') { // ... } myFunction('value1');
function myFunction(int $param1, string $param2) { // ... }
\Namespace\Subnamespace\Class\method(); // AVOID
// AVOID: Creates ambiguous function calls function f1() { // ... } function f2() { // ... } $f = f1' as; $f(); // Which function is called?
function myFunction($param) { // ... } myFunction([]); // May throw an error if $param is not an array
Consider the following code snippet:
namespace App\Controllers; use App\Models\User; class UserController { public function index() { $users = User::all(); return view('users.index', compact('users')); } }
Best Practice:
namespace
statement imports the UserController
namespace. use
statement to import the User
model. Anti-pattern:
App\Models\User
namespace. use
statement was not used to import the User
model. The above is the detailed content of Best practices and anti-patterns in PHP function calls. For more information, please follow other related articles on the PHP Chinese website!
