那这边获取'C'字符就很容易了,通过配合base64_decode的宽松解析特性进行一次base64_decode就能把除了A-Za-z0-9\/\=\+,其他字符会自动被忽略,然后再进行一次base64_encode就能恢复原来的字符串,结果如下所示 $url="php://filter/"; $url.="convert.iconv.UTF8.CSISO2022KR|convert.base64-decode|convert.ba...
是指使用PHP编程语言对经过base64编码的文件内容进行解码的过程。Base64是一种将二进制数据转换为可打印字符的编码方式,常用于在网络传输中传递二进制数据。解码base64文件内容可以将其转换回原始的二进制数据,以便进行进一步的处理或存储。 在PHP中,可以使用base64_decode()函数来解码base64文件内容。该函数接受一个ba...
