The DomainException class

<?phpfunction renderImage($imageResource, $imageType){  switch ($imageType) {  case 'jpg':  case 'jpeg':    header('Content-type: image/jpeg');    imagejpeg($imageResource);    break;  case 'png':    header('Content-type: image/png');    imagepng($imageResource);    break;  default:    throw new DomainException('Unknown image type: ' . $imageType);    break;  }  imagedestroy($imageResource);}?>

I think this kind of exception is perfect to throw when expected the  type of parameter, value etc. is good, but its value is out of domain. Look at RangeException:>>Exception thrown to indicate range errors during program execution. Normally this means there was an arithmetic error other than under/overflow. This is the runtime version of DomainException.<<So, this kind of exception is designed for logic errorWhen datatype is wrong, the better way is throwing InvalidArgumentException. <?php// Here, use InvalidArgumentExceptionfunction media($x) {    switch ($x) {        case image:            return 'PNG';        break;        case video:            return 'MP4';        break;        default:            throw new InvalidArgumentException ("Invalid media type!");    }}?>This is completly diffirent situation than this:<?php// Here, use DomainException$object = new Library ();try {    $object->allocate($x);} catch (toFewMin $e) {    throw new DomainException ("Minimal value to allocate is too high").}?>The simillar situation, but problem occurs during runtime:<?phpclass library {    function allocate($x) {        if ($x<1000)            throw new RangeException ("Value is too low!")    }}?>Summary: DomainException corresponds to RangeException and we should use them in simillar situations.  But first exception is designed to use when we are sure the problem is with our project, third-part elements etc. (simply: logical error), the second way is designed to use when we are sure the problem is with input data or environment (simply: runtime error).

<?phpfunction divide($divident, $divisor) {    if(!is_numeric($divident) || !is_numeric($divisor)) {        throw new InvalidArgumentException("Function accepts only numeric values");    }    if($divisor == 0) {        throw new DomainException("Divisor must not be zero");    }    return $divident / $divisor;}
