python 可以 [0]*99
php 是否也有类似的
不是 range(0,99)，所有值都是 0

我要把这段改成 php
def decode(data):
version = data[0:5]
if version.lower() == b'vc_01':
loc2 = data[5:]
length = len(loc2)
loc4 = [0]*(2*length)
for i in range(length):
loc4[2*i] = loc2[i] >> 4
loc4[2*i+1]= loc2[i] & 15;
loc6 = loc4[len(loc4)-11:]+loc4[:len(loc4)-11]
loc7 = [0]*length
for i in range(length):
loc7[i] = (loc6[2 * i] << 4) +loc6[2*i+1]
return ''.join([chr(i) for i in loc7])
else:
return data
节约生命，还是用 python

似乎没有， PHP 没有 python 那么多酷的语法糖， PHP 就是一堆函数

写循环吧，那只是个语法糖，无关乎优雅
