string base64_decode ( string $encoded_data )base64_decode() 对 encoded_data 进行解码，返回原始数据，失败则返回 FALSE。返回的数据可能是二进制的。实例说明 例-1 使用base64_decode()函数对简单字符串进行解码。＜?php $str = 'VGhpcyBpcyBhbiBlbmNvZGVkIHN0cmluZw==';echo base64_decode($str);?
我们应该comfortable with hex, binary and decimal 之间的conversion. 有一张现成的ASCII table. (网上有很多,我下面附一个直接带binary value的) Base64 Table Base64 Encoding的原理 大白话是这样。给定一个bits序列,从最左开始,按顺序每6-bit 为一组进行分组,这样每一组可以表示最多2的6次方,也就是64个字...
