Do all mysqli PHP functions have mysqli or do some have just mysql? -

-

i learned there 2 types(?) of mysql functions--mysql , mysqli. on w3schools, mysql functions included in php section http://www.w3schools.com/php/php_ref_mysql.asp. if turn mysql function mysqli function, add on 'i' ? instance, function mysql_select_db(), change mysqli_select_db() same function in mysqli version?

if yes, there mysql functions couldn't this?

and finally, there mysqli functions don't have mysql equivalent , there up-to-date list of them anywhere?

the mysqli_* functions provided mysqli php module superset of mysql_* functions. supersede , replace mysql module, though both available on servers compatibility reasons. mysqli stands mysql improved.

in reality, should using pdo new code, not either of these sets of functions.

for information despite this:

re: w3 schools, please have read of site. quite correct lot of things, including poor php tutorials @ w3 schools. the php documention @ php.net comprehensive, date , in cases good.

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.
