I have an array that looks something like this

PHP Code:

 Array

(

    [title] => Array

        (

            [0] => New title

            [5] => Default title

            [3] => Old Title

        )

    [addr] => Array

        (

            [0] => New title

            [5] => Default title

            [3] => Old Title

        )

) 

I need to have it sorted on the keys of the inner arrays so the result is

PHP Code:

Array

(

    [title] => Array

        (

            [0] => New title

            [3] => Old Title

            [5] => Default title

        )

    [addr] => Array

        (

            [0] => New title

            [3] => Old Title

            [5] => Default title

        )

)[/ 

I tried using this code but it doesn't work.

PHP Code:

 function MultiKeySort($k)

 {

   if (! is_array($k))

    $k = array();

    

   foreach ($k as $key)

   {

     ksort($key);

   } 

   return $k;

 }

$myArry = MultiKeySort($myArray); 

Would someone please explain how to get this sorted correctly?

You need to change the array and the foreach loop in the function.
Try this:

PHP Code:

function MultiKeySort($k) 

 { 

   if (! is_array($k)) 

    $k = array(); 

     

   foreach ($k as $key => $val) 

   { 

     ksort($val); 

     $k[$key] = $val;

   }  

   return $k; 

 } 

$myArry = MultiKeySort($myArray); 

Hope that helps,

PHP Code:

function MultiKeySort(&$arr)
{
    foreach($arr as $k=>&$v)
    {
        if(is_array($v))
        {
            MultiKeySort($v);
        }else{
            ksort($arr);
            break;
        }
    }
} 

I was going to suggest this. It works just as expected, although I'm not 100% that it is perfect

Thank you very much. It works great.

No problem, not sure if you wanted a recursive function like Jay made... but my one will work for your array.

I actually didn't notice the difference. I thought he had just quoted your code and was commenting on it. Thanks for the code Jay.

The difference is that my code will sort the top most array for each array element, where as the one supplied by Lex is for a 'static' format array type. Also, mine is passed by reference rather than by value, therefore you are editing the array directly, rather than having to return an array, so simply using

PHP Code:

MultiKeySort($myArry); 

will sort it (Note there is no '$myArry=' before it). Either way, as long as one works

Wow another good idea Jay, I always forget about the referencing symbol.
I use that technique alot these days Thanks.

Lol, I only thought about it cos i was too lazy to code it another way
