Getting all values from a specific array within a multidimentional array

Question

I've been searching around quite a bit for an answer for this, but I'm afraid that I've been unable to figure out a solution to this problem. I've created a multidimensional array which includes zip code information. However, I've been unable to pull the values out of it in the way that I need to. Here's an example of the print_r():

Array ( 
[0] => Array ( 
    [0] => 59101 
    [1] => 0.0 )
[1] => Array ( 
    [0] => 59102 
    [1] => 5.0 )
[2] => Array ( 
    [0] => 59105 
    [1] => 6.8 )
[3] => Array ( 
    [0] => 59106 
    [1] => 9.2 )
[4] => Array ( 
    [0] => 59037 
    [1] => 12.7 )
[5] => Array ( 
    [0] => 59044 
    [1] => 13.9 )
[6] => Array ( 
    [0] => 59002 
    [1] => 16.6 )
[7] => Array ( 
    [0] => 59079 
    [1] => 19.3 )

)

I need to look through the array for a specific zip code, and then get distance (the second value in each array) associated with that zip code. I'd considered restructuring the array, but I'm unsure of how to accomplish it. Here's my current code:

EDIT## sorry, I may not have been clear. The below code is what I'm using to build the array, not to extract information from the array. I have not idea how to get the information out of the array.

$rArray = array();
foreach ($points as $point){
    $zips = $point->Postcode;
    $dists =  number_format($point->D,1);
    array_push($rArray,array($zips,$dists));
}

Any thoughts on the best way to accomplish this? Thanks!

You guys have me thinking about this differently; right now I've just creating an array and then trying to extract the information using a seperate php file. I'll try accomplishing this without using an array, and going to a function instead. — Steve Dimock

Got it! Used a variation of Prashank's method. Thank you everyone for taking the time to help me out! — Steve Dimock

This?

EDIT: After your question update.

function getDistanceByZip($zip) {
   $array = //your array here;
   foreach($array as $value) {
      if($zip == $value[0]) {
         return $value[1];
      }
   }
   return false;
}

Thanks Prashank! This ended up working out great for me; I ended up not using it as a function, but as a loop within the Wordpress loop that I'm working in.

Maybe this?

foreach ($points as $point){
   if ($point->Postcode === $codeIamLookingFor) {
       echo "Distance: " . number_format($point->D, 1);
   }
}

function arrayseek($array, $zip){
   foreach($array as $k => $v){
       if($v[0] == $zip){
           return $v[1];
       }
   }
   return false;
}

If possible its often nice to give a little narrative to your answer to explain what's going on.
