Fast PHP format data format format

Question

I have a PHP frontend and a C ++ backend, and I need to be able to send groups of names to the front end. What serialized format will be the most efficient / fastest for reading PHP?

Data examples

group1:
  name1 3923
  name2 9879
  name3 8944
group2:
  name5 9823
group3: 
  name9 9822
  name1 4894

What would be the fastest to read PHP?

• XML

• Protocol buffer
• Comma / Space Limit our own system
• Anything else? other?
