biginteger-php字節數組如何轉化為bigint

php字節數組如何轉化為bigint

php得到的ASCII組成的數組
$array('-115','-101','97','-26','-80','-109','-92','33','-6','71','-122','-64','-17','-29','-101','-53','88','-93','-22','-104');
請問如何轉化為如下數據
-653068794747578802236590292838260814592085857640

java中是用biginteger轉化的，
String sig = new BigInteger(bytes).toString();
bytes為字節數組['-115','-101','97','-26','-80','-109','-92','33','-6','71','-122','-64','-17','-29','-101','-53','88','-93','-22','-104']
