PHP Arrays diff -


having $age = array("peter"=>"35", "ben"=>"37", "joe"=>"43"); $age2 = array("peter"=>"peter", "ben"=>"ben");

i want output like: $age = array("peter"=>"35", "ben"=>"37"); // without joe , same index

so want compare $age1 , $age2 , remove $age1 entry isn't in $age2? use array_diff_key() so:

$missingelements = array_diff_key($age2, $age1);  foreach($missingelements $element) { // each element not in both arrays     $index = $age1.indexof($element);      unset($age1[$index]); }  var_dump($age1); // print on screen

this php function compares key of 2 arrays , returns difference. loop on each element returned function , remove them $age1;

does autofac support specifying registration name in components' constructors? example: ninject's namedattribute . you need use autofac.extras.attributed package on top achieve this so let's have 1 interface , 2 classes: public interface ihello { string sayhello(); } public class englishhello : ihello { public string sayhello() { return "hello"; } } public class frenchhello : ihello { public string sayhello() { return "bonjour"; } } then have consumer class, in want select instance injected: public class helloconsumer { private readonly ihello helloservice; public helloconsumer([withkey("en")] ihello helloservice) { if (helloservice == null) { throw new argumentnullexception("helloservice"); } this.helloservice = helloservice; } public string sayhello() { return this.helloservice.sayhello()...

i've code snippet following in testbench function void write_to_port( my_data_type_base data ); my_data_type_extended data_ext; if(!$cast(data_ext, data)); `uvm_error(get_type_name(), "failed cast"); `uvm_info(get_name(), $psprintf("data_ext :\n%s", data_ext.sprint()), uvm_medium) // write data_ext out port.... endfunction when run it, i'm getting uvm_error "failed cast." i'm not quire sure why $cast not returning 1. can see, i'm printing out extended class data item after casting uvm_info. can see it's being cast properly. if don't use $cast if condition, don't runtime error. isn't coding practice use if dynamic cast check if $cast returning 1 ? what might reason behind cast not returning 1 in above case? i think semicolon on line 'if' not belong? i think consumes if statement, , uvm_error executes regardless of how if evaluates: if(!$cast(data_ext, data)); <- no semico...
