How do I actually combine 2 array into one and have one array assigned being the key and another array being the value.

This is how the 2 array look like.

PHP Code:

// Weight

Array

(

    [0] => 0.15

    [1] => 1.05

    [2] => 1.05

    [3] => 1.05

    [4] => 1.05

    [5] => 1.05

    [6] => 1.05

    [7] => 1.05

    [8] => 1.05

    [9] => 0.45

    [10] => 1.05



)

// Name

Array

(

    [0] => Li

    [1] => Keo

    [2] => Tan

    [3] => Baj

    [4] => Koh

    [5] => Jack

    [6] => Yeap

    [7] => Dan

    [8] => Blair

    [9] => Ninny

    [10] => Kenny

) 

And change to.

PHP Code:

Array

(

    [Name] => [Weight]

) 

Thanks.

I have found the answer. There's this function that does the trick.

PHP Code:

/*
    Name:         array_merge_assoc
    Author:     Markus Diersbock
    Details:     Takes two related indexed arrays and
            combines them into one associative array.
            
    Notes:        If $keyarray is NOT greater or equal to $valuearray
            the function will error unless the optional $force=TRUE.

    Revisions:    2003/12/13 - Created
            2004/01/14 - Added code for unequal arrays
*/


function array_merge_assoc($keyarray, $valuearray, $force=FALSE){
    $i=0;

    if ((count($keyarray) >= count($valuearray)) || $force==TRUE) {
        foreach($keyarray as $element){
            $aryreturn[$element]=$valuearray[$i++];
        }
    } else {
        return 'Arrays are not of equal size';
    }

    return $aryreturn;
}

Even easier:

PHP Code:

$array = array_combine($names, $weights); 

PHP: array_combine - Manual

I know. But if I use array_combine, it won't return a full list. It will just return array containing 0.15,0.45 and 1.05.

Ok, now I have this:

PHP Code:

Array
(
    [Li] => 0.15
    [Keo] => 1.05
    [Tan] => 1.05
    [Baj] => 1.05
    [Koh] => 1.05
    [Jack] => 1.05
    [Yeap] => 1.05
    [Dan] => 1.05
    [Blair] => 1.05
    [Ninny] => 0.45
    [Kenny] => 1.05
) 

And this particular function:

PHP Code:

// Took this code from php.net
function unique_events($array){
    //checks $array for duplicate values and returns an
        //array containing the keys of duplicates
   // It was supposedly to be array_intersect_assoc, however, it doesn't return me any result.
   // So I changed to array_intersect.
    $count= array_intersect($array, array_flip( array_count_values($array)));
    print_r($count);
    foreach($array as $key=>$value){
        if (in_array($value,$count)){
            $return[$value][]=$key;
        }
    }
    return $return;
} 

And it works fine and gave me the result I wanted. But I notice that it always return me one less value from the original array. The result as below:

PHP Code:

Array
(
    [1.05] => Array
        (
            [0] => Keo
            [1] => Tan
            [2] => Baj
            [3] => Koh
            [4] => Jack
            [5] => Yeap
            [6] => Dan
            [7] => Blair
            [8] => Kenny
        )

    [0.45] => Array
        (
            [0] => Ninny
        )

) 

As you can see, it's missing of one value. Which should also include.

PHP Code:

Array
(
    [0.15] => Array
        (
            [0] => Li
        )
) 

Why is it so?

Again, I have found the solution from php.net. Arghh... It's always after I posted and then I found the answer.
