php - Hightest value of an associative array -

-

is there easy way hightest numeric value of associative array? 

$array = array(     0 => array(         'key1' => '123',         'key2' => 'values we',         'key3' => 'do not',         'key4' => 'care about'     ),     1 => array(         'key1' => '124',         'key2' => 'values we',         'key3' => 'do not',         'key4' => 'care about'     ),     2 => array(         'key1' => '125',         'key2' => 'values we',         'key3' => 'do not',         'key4' => 'care about'     ) );  awesomefunction($array, 'key1'); // returns 2 ($array key)

please kind since question written phone. thanks.

if know data in format, should work.

function getmax( $array ) {     $max = 0;     foreach( $array $k => $v )     {         $max = max( array( $max, $v['key1'] ) );     }     return $max; }

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.
