I see no sense in this to check isset anded with is_array. If it is an array 
it must be also be set. So the first parameter is redundant. 

See php.net 

bool is_array ( mixed $var ) 

Finds whether the given variable is an array. 

>> if (isset($conf['constraints']['conflicts']) &&
>> is_array($conf['constraints']['conflicts'])) {
