二进制数据转十进制字符串

二进制数据转十进制字符串求助
我有一串Base64后的数据解开后是二进制的数据,求助怎么把这串二进制数据转换成十进制然后以字符串形式输出呢? 我试过bindec()这个函数转 ,但是得到的是0. 很费解啊 其他进制转换函数也试过了,但是好像都不行啊.

一下是我Base64原数据

PHP code

$data = base64_decode('V3FwMbiBTiYKVBXgO68BwSRWUXQETmISFVKmKWb2P7bgn/b49neYqikxbO8l9ZsnZ2hqHauZXEHMDmj5wKCXd59bSLmidYwdAojwUMNt4Uh3DkRa+PTAViKCYyUfrj1lmuE6pe5mI5ol/FwwZGn6Z1OTYlDo8BZLrYHhl2FKyW8=');
    
$t0 = current(unpack('H*',$data));
$t1 = "57717031b8814e260a5415e03baf01c124565174044e62121552a62966f63fb6e09ff6f8f67798aa29316cef25f59b2767686a1dab995c41cc0e68f9c0a097779f5b48b9a2758c1d0288f050c36de148770e445af8f4c056228263251fae3d659ae13aa5ee66239a25fc5c306469fa6753936250e8f0164bad81e197614ac96f";

var_dump($t0 == $t1); <div class="clear">
                 
              
              
        
            </div>
