remove element from array php -


my first array like:

array ( [0] => array ( [column_name] => ben_firstname ) )

second array:

array ( [0] => array ( [column_name] => ben_unique_id )         [1] => array ( [column_name] => ben_firstname )         [2] => array ( [column_name] => ben_lastname )         [3] => array ( [column_name] => ben_middlename ) )

i want remove ben_firstname (which in first array) second array...

i tried array_diff function. but, getting error.

code:

print_r(array_diff($first_array, $second_array));

error:

 message: array string conversion

thanks help.

you can't use array_diff directly because function expects array elements scalar, while in case arrays.

the correct solution use array_udiff callback determines equality looking @ column_name key of each array:

$result = array_udiff(      $second,      $first,       function($x, $y) { return strcmp($x['column_name'], $y['column_name']); } );

see in action.

inversion of control - Autofac named registration constructor injection -

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()...
