how to implement aes-128-ecb encryption with php or golang

here is the lua code

local aes = require 'resty.aes'

local cipher = aes:new('0123456789123456', nil, aes.cipher(128, 'ecb'))

print(ngx.encode_base64(cipher:encrypt('foobar')))

the output should be rTeNAHEZtzsyn1dDAujGgQ==

blow is my php code

var_dump(base64_encode(openssl_encrypt('foobar', 'aes-128-ecb', '0123456789123456', OPENSSL_RAW_DATA)));

the output should be AIIiZT3RO/bkseLE0Mcopg==

how can i get the lua result with php code. pls help me, thanks.

Start by comparing the shown resty.aes configuration with the PHP openssl_encrypt call, including the AES mode, key, padding, and base64 handling. Reproduce both outputs and determine whether the differing ciphertext is caused by mismatched options; done means documenting the equivalent configuration or the remaining incompatibility.
