Answer / kiran

var_dump also displays the variable type (int, string,
array, etc.) and "length".

Answer / nimesha

Print_r will display only values,but var_dump will display
data types too

Eg :
<?php
$a = array('aaa','bbb',11);
?>

Output of var_dump :
array(3) { [0]=> string(3) "aaa" [1]=> string(3) "bbb"
[2]=> int(11) }

Output of print_r :
Array ( [0] => aaa [1] => bbb [2] => 11 )

Answer / rubina

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"
