Dynamic Comparison Operators in PHP

Question

Is it possible, in any way, to pass comparison operators as variables to a function? I am looking at producing some convenience functions, for example (and I know this won\'

Answer 1

The top answer recommends a small class, but I like a trait.

trait DynamicComparisons{

private $operatorToMethodTranslation = [
    '=='  => 'equal',
    '===' => 'totallyEqual',
    '!='  => 'notEqual',
    '>'   => 'greaterThan',
    '<'   => 'lessThan',
];

protected function is($value_a, $operation, $value_b){

    if($method = $this->operatorToMethodTranslation[$operation]){
        return $this->$method($value_a, $value_b);
    }

    throw new \Exception('Unknown Dynamic Operator.');
}

private function equal($value_a, $value_b){
    return $value_a == $value_b;
}

private function totallyEqual($value_a, $value_b){
    return $value_a === $value_b;
}

private function notEqual($value_a, $value_b){
    return $value_a != $value_b;
}

private function greaterThan($value_a, $value_b){
    return $value_a > $value_b;
}

private function lessThan($value_a, $value_b){
    return $value_a < $value_b;
}

private function greaterThanOrEqual($value_a, $value_b){
    return $value_a >= $value_b;
}

private function lessThanOrEqual($value_a, $value_b){
    return $value_a <= $value_b;
}

}
