How to fetch immidiate next element of array in PHP

I have array of following form 

$a = array(
      [0] => 
      [address_country] => 
      [1] => 2011-11-29 14:49:10
      [createdtime] => 2011-11-29 14:49:10
    )

I am parsing this array using a for loop

for($i = 0; $i < count($a); $i++){

}

Now I want retrieve key of 2nd element as I parse it

For if i = 0, then i need some way of knowing that it's corresponding column name is address_country

Is there any way for this?

Please note I have to stick with for loop only

try this. I think this is what you want 

$c = array_values($a);
for($i = 0; $i < count($c); $i++){
    if(count($c)-1 > ($i)) {
   if(array_search($c[$i+1],$a) == "address_country")
   echo "found";
    }
}

For example, use array_keys():

$a = array(
      0 => '',
      'address_country' => '',
      '1' => '2011-11-29 14:49:10',
      'createdtime' => '2011-11-29 14:49:10'
    );

$keys = array_keys($a);
$i    = 1;
$m    = count($keys);

foreach($a as $key=>$value)
{
   echo(sprintf('My key is [%s] and my next neighbor key is [%s]'.PHP_EOL, $key, $i<$m?$keys[$i++]:null));
}

this will result in

My key is [0] and my next neighbor key is [address_country]
My key is [address_country] and my next neighbor key is [1]
My key is [1] and my next neighbor key is [createdtime]
My key is [createdtime] and my next neighbor key is []

note, that for last element next key will be treated as null
