PHP uses 3DES encryption and decryption, encryption mode ECB

PHP, 3DES encryption and decryption, see the following code encryption mode ECB, encryption method

/**
 * Encrypt
 * @param $data
 * @return string
 * @DateTime 2019-02-22  10:28
 */
public function encrypt($data, $key)
{
    $encData = openssl_encrypt($data, 'DES-EDE3', $key, OPENSSL_RAW_DATA);
    $encData = base64_encode($encData);
    return $encData;
}

/**
 * Decrypt
 * @param $data
 * @return string
 * @DateTime 2019-02-22  10:30
 */
public function decrypt($data, $key)
{
    $data    = base64_decode($data);
    $decData = openssl_decrypt($data, 'DES-EDE3', $key, OPENSSL_RAW_DATA);
    return $decData;
}

Why not mcrypt use openssl?

ps: the PHP7.1 removed mcrypt, and my PHP version 7.2, so you want to use openssl

Why encryption mode with DES-EDE3, rather than similar DES-EDE3-ECB this

ps: openssl does not support the ECB mode

Pictures from the original segment Fault 3DES in the end not to support ECB mode?
