Search array for index and return value?

[msaz87]

Hey all,

 

I have two related arrays, one of which I'm sorting and what I'm wondering is if you can search the second array by an index value and returning its value.

 

The first array, $first_array, is sorted so it looks like this:

Array ( [5] => 6 [2] => 6 [1] => 2 [6] => 2 [3] => 2 [0] => 2 [4] => 2)

 

And the other array, $second_array, is more like:

Array ( [0] => 4 [1] => 2 [2] => 12 [3] => 9 [4] => 7 [5] => 20 [6] => 21)

 

So you could search by index value "5" from the first array and return the value "20" from the second.

 

Something like:

foreach($first_array as $key => $value){

echo "FIRST VALUE: ".$value;

$second_value = XXsearch_arrayXX($second_array,$key);

echo "SECOND VALUE: ".$second_value;

}

 

Is this possible?

 

Any help is greatly appreciated -- thanks!

mmmm

Sometimes reading the manual can help.

 

Edit:

But if the value is just the index, there is not even a need to do this would suffice:

 if (isset($second_array[$key])) {
     $second_value = $second_array[$key];
}

 

Simple as that.
