You already assigned something to "var" here "new var = dini_Int(filename2,"Int");" , then y are you assigning something else to var here? var=var+raison; . I think thats the issue , you could try replacing

PHP код:

var=var+raison;
to 
new "variable name"=var+raison; 


Because variables are containers so it can hold one at a time.

Aren't you trying to save a string? you cant do it like that
