如何从openssl_decrypt文本和密钥中提取？ - PHP

I'm trying to encrypt a word with a key and i found out openssl_encrypt.

Now (maybe) i'm able to do it but i can't to extract from it initial word and secret key.

 $text = "message";
 $method = "aes-128-gcm";
 $ivlen = openssl_cipher_iv_length($method);
 $iv = openssl_random_pseudo_bytes($ivlen);
 $secretKey= "god";


if (in_array($method, openssl_get_cipher_methods())){       
  $encrypted = openssl_encrypt($text, $method, $secretKey, $options=0, $iv);
  $decrypted = openssl_decrypt($encrypted, $method, $secretKey, $options=0, $iv);

  print_r($encrypted);

  print_r($decrypted);  
}

Besides when decryption is correct output is FALSE or TRUE ?

It's because you're using gcm, change $method to "aes-128-cbc"
