search php object for empty value - php

Question

Looking for best way to accomplish below. I want to return TRUE if ANYTHING is empty in my user object, I don't care which one is empty. I think I've done this before with searching for empty values in an array but can't think of the best way to do this with objects.
I know I can loop thru the object and break once I find an empty value in the object, but checking first to see if there is a better way of doing this, thanks!
function is_it_empty($user)
{
$is_it_empty = FALSE;
if( isset($user->first_name) )
$is_it_empty = TRUE;
if( isset($user->last_name) )
$is_it_empty = TRUE;
return $is_it_empty;
}
also:
function name($user)
{
foreach($user as $u):
if( isset ($user->value) ): // or should it be isset?
return true;
break;
endif;
endforeach;
return true;
}

Answer 1

$user = new stdClass();
$user->firstName = 'Mark';
$user->lastName = 'Baker';
$user->sanity = NULL;
function is_it_empty($user) {
foreach($user as $property) {
if (empty($property)) {
return true;
}
}
return false;
}
var_dump(is_it_empty($user));

Answer 2

u can use foreach. it's better than ur code.
function is_it_empty($user)
{
foreach($user as $key=>$value)
{
if( empty($value) ){
return = TRUE;
}
}
}

In case any one ever happens to care about encapsulation, this code might come in handly. The first function inspect public attributes only.
function is_prop_empty( $object ) {
$reflect = new ReflectionClass($object);
$props = $reflect->getProperties();
foreach ($props as $prop) {
try {
$result = $prop->getvalue( $object );
if( $result === null ) {
return true;
}
} catch( Exception $e ) {
}
}
return false;
}
var_dump( is_prop_empty($user) );
And with this second one, you can look into private and protected properties:
function is_prop_empty( $object ) {
$reflect = new ReflectionClass($object);
$props = $reflect->getProperties();
foreach ($props as $prop) {
$prop->setAccessible(true);
$result = $prop->getvalue( $object );
if( $result === null ) {
return true;
}
}
return false;
}
EDIT
By empty, i assumed you meant null but you can modify the function(s) above to meet your requirements of "empty".

I think having this generic function to check if a value exists would do the job
function is_empty($data) {
if(empty($data) || !isset($data) || $data == false) {
return true;
}
return false;
}
