1. make sure the generated keys are equal 2. You have different result encoding (hex vs base64). As well you are using differet IV (in both cases IV is used unsafe way)
– gusto2
Nov 20 '18 at 12:23
Can you please guide me what code should I use for IV in php case to match the result? Thanks
– Ankit S.
Nov 20 '18 at 12:27
IV needs to be the same, it is usually random array passed along the ciphertext
– gusto2
Nov 20 '18 at 12:28
In java case, it is {1,2,3....} I am not getting what should I write in PHP. It should be of 16 bytes and should be a string and Java it is an array... How can I make it same in PHP?

Can you help me with code? Thanks for your help..

I dont know why it is happening.
Length of the string is same but result are different.
How to get the similar result as in java?

1. make sure the generated keys are equal 2. You have different result encoding (hex vs base64). As well you are using differet IV (in both cases IV is used unsafe way)

Can you please guide me what code should I use for IV in php case to match the result? Thanks
– Ankit S.
Nov 20 '18 at 12:27
IV needs to be the same, it is usually random array passed along the ciphertext
– gusto2
Nov 20 '18 at 12:28
In java case, it is {1,2,3....} I am not getting what should I write in PHP. It should be of 16 bytes and should be a string and Java it is an array... How can I make it same in PHP?

I have solved your code by using below code Hope this may help you
public function encrypt($data, $key = "4A8A53E16C9C34EA5E77EF9FF7B2FD04", $method = "AES-256-CBC") {
$salt="178";
//Converting Array to bytes
$iv = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15];
$chars = array_map("chr", $iv);
$IVbytes = join($chars);
$salt1 = mb_convert_encoding($salt, "UTF-8"); //Encoding to UTF-8
$key1 = mb_convert_encoding($key, "UTF-8"); //Encoding to UTF-8
//SecretKeyFactory Instance of PBKDF2WithHmacSHA1 Java Equivalent
$hash = openssl_pbkdf2($key1,$salt1,'256','65536', 'sha1');
$encrypted = openssl_encrypt($data, $method, $hash, OPENSSL_RAW_DATA, $IVbytes);
return bin2hex($encrypted);
}

Please note the solution not cryptographically secure. Using static IV with reusing the same key (having static salt) may not produce fully secure solution
