Importing all external classes in a file through use statements makes them clearly visible.
Example
function make() {
return new \stdClass();

The method __invoke uses an else expression. Else clauses are basically not necessary and you can simplify the code by not using them. Open

return [];

ElseExpression
Since: 1.4.0
An if expression with an else branch is basically not necessary. You can rewrite the conditions in a way that the else clause is not necessary and the code becomes simpler to read. To achieve this, use early return statements, though you may need to split the code it several smaller methods. For very simple assignments you could also use the ternary operations.
Example
class Foo
{
public function bar($flag)
{
if ($flag) {
// one branch
} else {
// another branch
}
}
}Source https://phpmd.org/rules/cleancode.html#elseexpression
The method __toString uses an else expression. Else clauses are basically not necessary and you can simplify the code by not using them. Open

Avoid unused private fields such as '$loggerFileName'. Open

UnusedPrivateField
Since: 0.2
Detects when a private field is declared and/or assigned a value, but not used.
Example
class Something
{
private static $FOO = 2; // Unused
private $i = 5; // Unused
private $j = 6;
public function addOne()
{
return $this->j++;
}
}Source https://phpmd.org/rules/unusedcode.html#unusedprivatefield
Avoid variables with short names like $ex. Configured minimum length is 3. Open
$ex = new \Exception($exceptionString);- Read upRead up
- Exclude checks
ShortVariable
Since: 0.2
Detects when a field, local, or parameter has a very short name.
Example
class Something {
private $q = 15; // VIOLATION - Field
public static function main( array $as ) { // VIOLATION - Formal
$r = 20 + $this->q; // VIOLATION - Local
for (int $i = 0; $i < 10; $i++) { // Not a Violation (inside FOR)
$r += $this->q;
}
}
