Convert PHP array into Key => Value Array

Total PHP Noob and I couldn't find an answer to this specific problem. Hope someone can help!

$myvar is an array that looks like this:

Array (  
 [aid] => Array (  
  [0] => 2  
  [1] => 1  
 )  
 [oid] => Array(  
  [0] => 2  
  [1] => 1  
 )  
)

And I need to set a new variable (called $attributes) to something that looks like this:

$attributes = array(
 $myvar['aid'][0] => $myvar['oid'][0], 
 $myvar['aid'][1] => $myvar['oid'][1], 
 etc...
);

And, of course, $myvar may contain many more items...

How do I iterate through $myvar and build the $attributes variable?

Your requirements are not clear. what you mean by "And, of course, $myvar may contain many more items..." there is two possibilties

1st. more then two array in main array. like 'aid', 'oid' and 'xid', 'yid' 2nd. or two main array with many items in sub arrays like "[0] => 2 [1] => 1 [2] => 3"

I think your are talking about 2nd option if so then use following code

$aAid = $myvar['aid'];
$aOid = $myvar['oid'];

foreach ($aAid as $key => $value) {
  $attributes['aid'][$key] = $value;
  $attributes['oid'][$key] = $myvar['oid'][$key];
}

You can itterate though an array with foreach and get the key and values you want like so

$attributes = array() 
foreach($myvar as $key => $val) {
   $attributes[$key][0] = $val;
}

use array_combine()

This will give expected result.

http://php.net/manual/en/function.array-combine.php

Usage:

$attributes = array_combine($myArray['aid'], $myArray['oid']);

Will yield the results as requested.

Somthing like this if I understood the question correct

$attributes = array();
foreach ($myvar['aid'] as $k => $v) {
    $attributes[$v] = $myvar['oid'][$k]; 
}
