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, ";

		foreach($po as $subpo) {

			$output .= $subpo["value"]." / ";

		}

		$output = substr($output,0,-3);

		echo $output."';\n";
