Looking at the info for Zend Extensions I have noticed that there are two members in the zend_extension struct called "op_array_persist" and "op_array_persist_calc". Looking at the PHP source code I can see that these hooks are used to add some data in memory to the opcode array but I can't think of a use case for this. Could someone explain what these hooks are for? Is there any example that I could check?
Cheers Barel
