Mam 2 tablice, druga tablica musi zawierać cały element pierwszej tablicy, jak to sprawdzić? Dziękuję Ci

<code>For example

array 1: Array ( [0] => Email [1] => 1_Name )
array 2:  Array ( [0] => 1_Name [1] => ) 

In this case it is invalid , as array 2 do not have Email

array 1: Array ( [0] => Email [1] => 1_Name )
array 2:  Array ( [0] => 1_Name [1] => Address [2]=> Email )

 In this case it is valid
