The method usePcntl has a boolean flag argument $install, which is a certain sign of a Single Responsibility Principle violation. Open

BooleanArgumentFlag
Since: 1.4.0
A boolean flag argument is a reliable indicator for a violation of the Single Responsibility Principle (SRP). You can fix this problem by extracting the logic in the boolean flag into its own class or method.
Example
class Foo {
public function bar($flag = true) {
}
}

Avoid using static access to class '\SAREhub\Component\Worker\Command\CommandReply' in method 'onStopCommand'. Open
$replyCallback($command, CommandReply::success($command->getCorrelationId(), 'stopped'));

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();
}
}

Avoid using static access to class '\SAREhub\Component\Worker\Command\CommandReply' in method 'onProcessCommandException'. Open
$replyCallback($command, CommandReply::error(
$command->getCorrelationId(),
'exception when execute command', [
'exceptionMessage' => $e->getMessage()
]));

Avoid assigning values to variables in if clauses and the like (line '104', column '7'). Open
private function checkCommand() {
if ($command = $this->getCommandInput()->getNext()) {
$runner = $this;
$replyCallback = function (Command $command, CommandReply $reply) use ($runner) {
$runner->getCommandReplyOutput()->send($reply, true);

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
// ...
}
}
}

Avoid variables with short names like $e. Configured minimum length is 2. Open

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;
}
}
