The difference between the two is:
Var_dump() returns the datatype also of the variable which
print_r() does not.

Eg:
$query="Select fname from table where id=20";
$result=mysql_query($query);
$row=mysql_fetch_row($result);

print_r($query);
o/p
---------------
SELECT fname FROM information where id=53

var_dump($query);
o/p
----------------
string(43) " SELECT fname FROM information where id=53"
