Add New Rows To Array

Question

I have an array which looks like the following:

Array (
 [class_name] => Array ( [0] => 1 [1] => 2 )
 [zone1_price] => Array ( [0] => 1 [1] => 2 )
 [zone2_price] => Array ( [0] => 1 [1] => 2 )
 [zone3_price] => Array ( [0] => 1 [1] => 2 )
 [zone4_price] => Array ( [0] => 1 [1] => 2 ) 
)

I want to be able to add new rows which will be:

Array (
 [class_name] => Array ( [0] => 3 )
 [zone1_price] => Array ( [0] => 3 )
 [zone2_price] => Array ( [0] => 3 )
 [zone3_price] => Array ( [0] => 3 )
 [zone4_price] => Array ( [0] => 3 )
)

which would then become:

Array (
 [class_name] => Array (  [0] => 1 [1] => 2 [2] => 3 )
 [zone1_price] => Array ( [0] => 1 [1] => 2 [2] => 3 )
 [zone2_price] => Array ( [0] => 1 [1] => 2 [2] => 3 )
 [zone3_price] => Array ( [0] => 1 [1] => 2 [2] => 3 )
 [zone4_price] => Array ( [0] => 1 [1] => 2 [2] => 3 )
)

I am thinking I will need to use array_merge but I also think I need to separate the arrays, give them a key of some sort then combine them and add then array them.

Where would I start with something like this?

You can do it like this

<?php
  $first=array(
    'class_name'=>array(1,2),
    'zone1_price'=>array(1,2),  
    'zone2_price'=>array(1,2),  
    'zone3_price'=>array(1,2),  
    'zone4_price'=>array(1,2),
    );
  $second=array(
    'class_name'=>array(3,4),
    'zone1_price'=>array(3,4),  
    'zone2_price'=>array(3,4),  
    'zone3_price'=>array(3,4),  
    'zone4_price'=>array(3,4),  
    );
  $fs=sizeof($first['class_name']);
  $ss=sizeof($second['class_name']);
  foreach($first as $k => $v)
  {
    for($i=$fs;$i<$ss+$fs;$i++)
    {
      $first[$k][$i]=$second[$k][$i-$fs];
    } 
  }
