Multiple foreach loops and accessing values outside

I'm trying to access multiple values in multiple foreach loops outside of the loops: 

foreach(array1 as arr1) {
    $var1 = arr2['value1'];  //$array is associative array with mutliple keys value1
}

Then I have another

foreach(array2 as arr2) {
    $var2 = arr2['value']; //$array2 is another associative array with multiple keys value
}

All of this is within another big foreach loop and now I want to create an array within the big foreach with $var1 and $var2 being used. This array I'm going to be creating is going to be an associative array as well. Any ideas how I can do this?

Array 1:

Array
(
  [0] => Array
    (
        [id] => 1
        [id_name] => 251452
        [name] => bob
    )

[1] => Array
    (
        [id] => 2
        [id_name] => 251453
        [name] => bob

    )

)

Array 2: 

Array
(
[0] => Array
    (
        [id_person] => 4
        [id_last_name] => 251452
        [last_name] => smith

    )

[1] => Array
    (
        [id_person] => 15
        [id_last_name] => 251453
        [last_name] => johnson
    )

)

Assume these come from two different queries from the database.

I want to get the first name from the first array for each one and get the last name from the second array for each one and make one array that has this data along with others.

Have a look into multi dimensional arrays.

Also have a look at stdclass and maybe creating an array of these which can store many variables within a single definition - which can help in many ways. (standard class)

Nested looping - this would just dump all sub arrays into an object // Object and array examples for an InnerArray

 $Object = new stdclass();
 $AllOfIt = array();
 $cnt = 0;
 foreach($OuterArray as $OuterKey => $InnerArray)
 {
      $cnt++;
      foreach($InnerArray as $InnerKey => $InnerValue)
      {
           $Object->$cnt = $InnerValue;
           $AllOfIt[$cnt] = $InnerValue;
      }
 }
