i simply use print_r and var_dump function for get the info of array.but i wonder they both giving a big difference. print_r is showing that array has 1 row whereas var_dump showing null on same array, here the output print_r showing this

   mysqli_result Object ( [current_field] => 0 [field_count] => 2 [lengths] => [num_rows] => 1 [type] => 0 )

whereas var_dump showing this on same array

object(mysqli_result)[4]
public 'current_field' => null
public 'field_count' => null
public 'lengths' => null
public 'num_rows' => null
public 'type' => null

i want to know what is the difference here... i thought both function same expect var_dump show data type also...

Can you show some code before the call to var_dump and print_r, as well as the calls? – Andrei Nikolaenko Feb 28 '15 at 09:43
$query="call findcty($this->ctycod)"; $result= mysqli_query($link, $query); var_dump($result); – Davinder kumar Feb 28 '15 at 09:45
your output is only possible if they are not the same object – Feb 28 '15 at 09:47
I would say your title should be more specific, because you are not asking for "what the difference in var_dump and print_r" but to your specific case, "why print_r and var_dump showing different results". And for that as @Dagon said, it seems like both functions are not applied on same object. – Vivek Vaghela Feb 28 '15 at 09:54
yes...i do not applied same function of same object.. i applied one at a time @Dagon – Davinder kumar Feb 28 '15 at 10:00
its not, its clearly not. there's nothing else to say – Feb 28 '15 at 10:01
