逆推解密

$data1 = openssl_decrypt($data1, 'AES-128-ECB',$key2,OPENSSL_RAW_DATA);
$data1 = strrev($data1);
$data1 = openssl_decrypt($data1, 'AES-128-ECB',$key1,OPENSSL_RAW_DATA);

加密

$data1 = openssl_encrypt($data, 'AES-128-ECB',$key1,OPENSSL_RAW_DATA);
$data1 = strrev($data1);
$data1 = openssl_encrypt($data1, 'AES-128-ECB',$key2,OPENSSL_RAW_DATA);

hex2bin
把字符串转换为十六进制值：

$key = hex2bin（$key）

bin2hex
把十六进制值转换为 ASCII 字符

$data = bin2hex($data);
