I'm trying to output the following strings based on the array below, but can't figure out how to group the values together:

'Option Number = 465, Option Name = CHTZMO / DYUIOP';
'Option Number = 568, Option Name = CHTZMO / PLOIYU';

Are all the items going to be under the elemnt
[po] => Array ?

So...

Foreach ($myarray['23']['po'] as $key=>$details) {
  echo "Option Number = " . $key . "  Option Name = " . $details[0]['value'] . "/" . $details[0]['value'] . "\n<br />";
}

Are you able to display more of the array? I don't see a 568...

The thing is though, the values in '23' will change, and there very well could be more than 2 iterations within that 465.  So, in the case of the example below, the first string would like this:

'Option Number = 465, Option Name = CHTZMO / DYUIOP / YTRION'

And the second:

'Option Number = 568, Option Name = CHTZMO / PLOIYU'

I'm trying to output the following strings based on the array below, but can't figure out how to group the values together:
 
'Option Number = 465, Option Name = CHTZMO / DYUIOP';
'Option Number = 465, Option Name = CHTZMO / PLOIYU';

Hi,

The example code outputs:

Handling foo number 23:
'Option number = 465, CHTZMO / DYUIOP';
'Option number = 568, CHTZMO / PLOIYU';
<?
$foo = array(
	23 => array(
		"aid" => "Item A",
		"gid" => 1, 
		"po" => array(
			465 => array(
				0 => array(
					"itemid" => 884,
					"value" => "CHTZMO", 
					"identifier" => 98765,
					"gp" => 187, 
					"type" => "select", 
					"attid" => 1086
				), 
				1 => array(
					"itemid" => 884,
					"value" => "DYUIOP", 
					"identifier" => 98765,
					"gp" => 187, 
					"type" => "select", 
					"attid" => 1086
				)
			),
			568 => array(
				0 => array(
					"itemid" => 884,
					"value" => "CHTZMO", 
					"identifier" => 98765,
					"gp" => 187, 
					"type" => "select", 
					"attid" => 1086
				), 
				1 => array(
					"itemid" => 884,
					"value" => "PLOIYU", 
					"identifier" => 98769,
					"gp" => 187, 
					"type" => "select", 
					"attid" => 1765
				)
			)
		)
	)
);
 
foreach($foo as $foonum => $subfoo){
	echo "Handling foo number $foonum: \n";
	foreach($subfoo["po"] as $option => $po){
		$output =  "'Option number = $option, ";
