php - from facebook, i want to fetch Hometown details . from it i want to saparate city,state, country -

-

from facebook, want fetch hometown details . want separate city,state, country. these fields separated comma. can split them comma.

my problem is: enter city name in hometown field of facebook, giving combination of city,state , country. sometime giving combination of city , country so, when split string comma, how know second element state or country.

i can 1 thing, can check length of array, if has 3 filed has city/state/county. else city/county.

is ture? can have more files.

just query fql user table: 

select hometown_location user uid=me()

this return like: 

[   {     "hometown_location": {       "city": "xxxxx",       "state": "xxxxx",       "country": "xxxx",       "zip": "xxxxx",       "id": xxxx,       "name": "xxx, xxx, xxxxx"     }   } ]

of course of fields empty if user didn't set them. (result set returned using fql.query test console)

c# - Is it possible to remove an existing registration from Autofac container builder? -

something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
