Question

I have the following array:

$users
: array = 
  0: array = 
    0: object(Person) = 
      strName: string = John
      strLastName: string = Smith
      strAge: string = 19
    1: object(Person) = 
      strName: string = Jean
      strLastName: string = Newton
      strAge: string = 22
  1: array = 
    0: object(Person)= 
      strName: string = John
      strLastName: string = Smith
      strAge: string = 19
    1: object(Person) = 
      strName: string = Jean
      strLastName: string = Newton
      strAge: string = 22
  2: array = 
    0: object(Person) = 
      strName: string = Martin
      strLastName: string = Marin
      strAge: string = 25    

In order to get rid of the duplicates I’ve done:

$users = array_map("unserialize", array_unique(array_map("serialize", $users)));

And I get:

$users
: array = 
  0: array = 
    0: object(Person) = 
      strName: string = John
      strLastName: string = Smith
      strAge: string = 19  
    1: object(Person) = 
      strName: string = Jean
      strLastName: string = Newton
      strAge: string = 22  
  1: array = 
    0: object(Person) = 
      strName: string = Martin
      strLastName: string = Marin                                                                                                        
      strAge: string = 25   

Now I have to get the info the array contains.
I’m doing:

$i=0;
foreach ($users as $u)
{
  echo $u [$i]->getName()); 
.
.
  $i++;
 }

But I’m not printing all the elements of the array, $u [2] is NULL.

What I’m I doing wrong?

Thanks a ton!

You have nested arrays: you need nested loops.

foreach ($users as $ulist) {
    foreach ($ulist as $u) {
        echo $u->getName(); 
    }
}
