NULL and null are the same thing. If I'm correct var_dump() was created
to solve the problem of not knowing what the datatypes are when using
print_r().

print_r converts null, which is a variable type, like integer, string,
float, etc, into an empty string.

null is case-insensitive, so it doesn't matter how you type it.

var_dump converts null into the string "NULL".

[PHP] PHP: array with null shows different with print_r and var_dump
Hello,
I am new to PHP and PHP community.
Following program outputs different values with print_r and var_dump.
$array = array(null, NULL);
print_r($array); prints values like below
Array
(
[0] =>
[1] =>
)
where as var_dump($array) prints values like below
array(2) {
[0]=>
NULL// Does this convert to null to NULL?
[1]=>
NULL
}
Can you tell me why the above difference?
