checksum calculation

Hello,

 

I'm parsing a data frame and need to calculate the checksum for the data integrity. I understand the logic and can do it in ms-excel manually whether it is correct but I could not use it with ^ (XOR) operator in PHP.

 

I've attached the excelsheet to make it obvious.

 

Please Help implementing it.

 

Regards
