[RESOLVED] How to sort multidimention array with user defined value?

[volant]

Dear all,

I have following array:
$arrField = array(
array("FIELD" => "MOBILE_PHONE", "VALUE" => "1111111"),
array("FIELD" => "HOME_PHONE", "VALUE" => "222222"),
array("FIELD" => "FAX_PHONE", "VALUE" => "333333"),
array("FIELD" => "WORK_PHONE", "VALUE" => "4444444"));

I want to sort the $aryField by user defined FIELD value.
For instance:
$sortby = array("FAX_PHONE", "WORK_PHONE", "HOME_PHONE", "MOBILE_PHONE");

The result will be:
$arrField = array(
array("FIELD" => "FAX_PHONE", "VALUE" => "333333"),
array("FIELD" => "WORK_PHONE", "VALUE" => "4444444"),
array("FIELD" => "HOME_PHONE", "VALUE" => "222222"),
array("FIELD" => "MOBILE_PHONE", "VALUE" => "1111111"));

Is there any predefined php function instead of create a function myself?
Hear your reply.
Thanks!

If you always have $arrField in the order given above, you could use array_multisort by specifying another array ordered accordingly

$arrField = array(
array("FIELD" => "MOBILE_PHONE", "VALUE" => "1111111"),
array("FIELD" => "HOME_PHONE", "VALUE" => "222222"),
array("FIELD" => "FAX_PHONE", "VALUE" => "333333"),
array("FIELD" => "WORK_PHONE", "VALUE" => "4444444"));

$order = array(3, 2, 0, 1);
array_multisort($order, $arrField);

printf('<pre>%s</pre>', print_r($arrField,1));

And if you do not know the order of the input array

$order = array('FAX_PHONE' => 0, 'WORK_PHONE' => 1, 'HOME_PHONE' => 2, 'MOBILE_PHONE' => 3);
$out = array();
foreach ($arrField as $a)
{
	$out[$order[$a['FIELD']]] = $a;
}
ksort($out);

printf('<pre>%s</pre>', print_r($out,1));

Should you have varying amounts of phone numbers for any given type, I'd create one array for each phone type and then [man]array_merge[/man] them into one array.
