loadConfig accesses the super-global variable $_SERVER. Open

Superglobals
Since: 0.2
Accessing a super-global variable directly is considered a bad practice. These variables should be encapsulated in objects that are provided by a framework, for instance.
Example
class Foo {
public function bar() {
$name = $_POST['foo'];
}
}

Cognitive Complexity
Cognitive Complexity is a measure of how difficult a unit of code is to intuitively understand. Unlike Cyclomatic Complexity, which determines how difficult your code will be to test, Cognitive Complexity tells you how difficult your code will be to read and comprehend.
A method's cognitive complexity is based on a few simple rules:
- Code is not considered more complex when it uses shorthand that the language provides for collapsing multiple statements into one
- Code is considered more complex for each "break in the linear flow of the code"
- Code is considered more complex when "flow breaking structures are nested"

Avoid assigning values to variables in if clauses and the like (line '108', column '50'). Open

$option = '--' . self::OPTION_APPCONFIG . '=';
foreach ($_SERVER['argv'] as $param) {

IfStatementAssignment
Since: 2.7.0
Assignments in if clauses and the like are considered a code smell. Assignments in PHP return the right operand as their result. In many cases, this is an expected behavior, but can lead to many difficult to spot bugs, especially when the right operand could result in zero, null or an empty string and the like.
Example
class Foo
{
public function bar($flag)
{
if ($foo = 'bar') { // possible typo
// ...
}
if ($baz = 0) { // always false
// ...
}
}
}

The method loadConfig() contains an exit expression. Open
exit("The configuration file does not exist: $path\n");

- Exclude checks
ExitExpression
Since: 0.2
An exit-expression within regular code is untestable and therefore it should be avoided. Consider to move the exit-expression into some kind of startup script where an error/exception code is returned to the calling environment.
Example
class Foo {
public function bar($param) {
if ($param === 42) {
exit(23);
}
}
}
