how serialize data on wordpress database?

example 

option_name               option_value ----------------------------------------------------------- widget_example-widget     a:3:{i:2;a:0:{}i:6;a:4:{s:5:"title";s:14:"example widget";s:4:"name";s:8:"john doe";s:3:"age";s:2:"30";s:3:"sex";s:4:"male";}s:12:"_multiwidget";i:1;}

example want call sex , use 

$sex = get_option('widget_example-widget'); echo $sex['sex'];

it return empty , when try var_dump result below

array(3) {   [2]=>   array(0) {   }   [6]=>   array(4) {     ["title"]=>     string(14) "example widget"     ["name"]=>     string(8) "john doe"     ["age"]=>     string(2) "30"     ["sex"]=>     string(4) "male"   }   ["_multiwidget"]=>   int(1) }

actually can retrieve data add $sex['6']['sex'] problem here [6]=> dynamic. when activate/deactivate widget can in value.

question

how correct data one?

i'm not sure of want, maybe try function check every array see if "sex" index isset, , return value if is. not efficient should anyway...

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...

c++ - Warning : overflow in implicit constant conversion -

in following program, line 5 give overflow warning expected, surprisingly line 4 doesn't give warning in gcc: http://www.ideone.com/u0bxn int main() { int = 256; char c1 = i; //line 4 char c2 = 256; //line 5 return 0; } i thinking both lines should give overflow warning. or there i'm missing? the topic led me experiment this: typedef type checking? there said following(which deleted answer, because when run it, didn't show had expected): //however, you'll warning case: typedef int t1; typedef char t2; t1 x = 256; t2 y = x; //possible overflow warning! (but doesn't give warning :() -wall doesn't include many options. -wconversion 1 of them , warns behavior you're interested in. see http://gcc.gnu.org/onlinedocs/gcc/warning-options.html
