Actual way of treat URIs

Actual.php

<?php

function verifyUri($value) {

   try {
       $uri = Zend\Uri\UriFactory::factory($value)
   } catch (Zend\Uri\Exception\InvalidUriPartException $e) {
       return false;
   }

   return $uri->isValid();
}

Proposed.php

<?php

function verifyUri($value) {

   $uri = Zend\Uri\UriFactory::factory($value)
   return $uri->isValid();
}

// Or

function verifyUri($value) {

   $uri = Zend\Uri\UriFactory::factory($value)
   if (!$uri->isValid()) {
       $errno   = $uri->getErrorCode();
       $message = $uri->getErrorMessage();
       throw new Exception($message, $errno);
   }
   return true;
}
