[SR-Users] Storing an integer value into AVP from REDIS string

[Steve Bucklin]

Daniel,

Thanks, you're a star! I dug into the old stuff that was inserting the 
values in REDIS, and *yes* there it was. The database was set as INT, 
however the php (7) json_encode was encoding all values as a string. 
There is a flag for that function called "JSON_NUMERIC_CHECK" that now 
forces the INT values where needed and the object now is passed as an 
INT, and then by the jansson_get() function to the avp.

Should have thought about that one. Thanks again :-)

Steve
