Missing class import via use statement (line '31', column '20').
Open

        return new \PHPWS_DB('intern_subject');
Severity: Minor
Found in class/Subject.php by phpmd

MissingImport

Since: 2.7.0

Importing all external classes in a file through use statements makes them clearly visible.

Example

function make() {
    return new \stdClass();
}

Source http://phpmd.org/rules/cleancode.html#MissingImport

Avoid using static access to class 'Intern\PdoFactory' in method 'getSubjects'.
Open

        $db = PdoFactory::getPdoInstance();
Severity: Minor
Found in class/Subject.php by phpmd

StaticAccess

Since: 1.4.0

Static access causes unexchangeable dependencies to other classes and leads to hard to test code. Avoid using static access at all costs and instead inject dependencies through the constructor. The only case when static access is acceptable is when used for factory methods.

Example

class Foo
{
    public function bar()
    {
        Bar::baz();
    }
}

Source https://phpmd.org/rules/cleancode.html#staticaccess

Call to method __construct from undeclared class \PHPWS_DB
Open

Severity: Critical

Avoid variables with short names like $db. Configured minimum length is 3.

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;
        }
    }
}
