PHP aes （ecb）解密后乱码问题

内容：abcd
KEY:1234567890123456
加密后base64：T7UT2NQ1AFvR9unjA0wKWA==

    function apiDataDecrypt($data, $key='') {
      $data = base64_decode($data);
      $pad = 16 - (strlen($data) % 16);
      $padData = $data . str_repeat(chr($pad), $pad);
      return mcrypt_decrypt(MCRYPT_RIJNDAEL_128, $key,$padData, MCRYPT_MODE_ECB);
    }    
    }

直接附上解决方案吧

    $key = '1234567890123456';
    $content = 'T7UT2NQ1AFvR9unjA0wKWA==';
    $desStr = decryptString($content,$key);
    echo($desStr);

    function decryptString($str,$key) {
      $str = base64_decode($str);
      $str = mcrypt_decrypt(MCRYPT_RIJNDAEL_128, $key, $str, MCRYPT_MODE_ECB);  
      $block = mcrypt_get_block_size('rijndael_128', 'ecb');
      $pad = ord($str[($len = strlen($str)) - 1]);
      $len = strlen($str);
      $pad = ord($str[$len-1]);  
      return substr($str, 0, strlen($str) - $pad);
    }
