Need help with code

Hey,

I need to create something like that:
I have a group of numbers like
1 - 2
1 - 6
1 - 34
1 - 4

2 - 5
2 - 7
2 - 11
2 - 43

what I need to do is to match second column to find out first column number
lets say I have 43 - script have to find that 43 belongs to 2
, its very easy to do with mysql, but this part have to be done only in php
probably with array

any ideas ?
thanks in advance

 

If you want to do this with array, show us the array structure? Like this below?

$array[1] = array(2,6,34,4);
$array[2] = array(5,7,11,43);

PHP:

 

I suppose that numbers in second column are unique, so there is no situation when 43 belongs to 1 and 2.
In that case make an array like that:

$numbers = array(
2  => 1,
6  => 1,
34 => 1,
4  => 1,
5 => 2,
7 => 2,
11 => 2,
43 => 2);

$result = array[43];

PHP:

 

Or if they're not unique, which is most likely;

$numbers = array(
1  => 2,
1  => 6,
1 => 34,
1  => 4,
2 => 5,
2 => 7,
2 => 11,
2 => 43);
$key = array_search('43', $numbers)

PHP:

 

So the main problem now is to make such an array.
deriklogov, tell us how are these numbers stored? Plain text, xml, database or what?

 

@AsHinE, your code should be :

$numbers = array(
2  => 1,
6  => 1,
34 => 1,
4  => 1,
5 => 2,
7 => 2,
11 => 2,
43 => 2);

$result = $numbers[43];

PHP:

@Sky AK47, the key is duplicated.

 

Thank you very much guys,
code working like a charm.


$numbers = array(
2 => 1,
6 => 1,
34 => 1,
4 => 1,
5 => 2,
7 => 2,
11 => 2,
43 => 2);

$result = $numbers[43];

Problem solved
THANK YOU
