You can do:

$newArray = $oldArray[0];

This will create a new array with the same key-value pairs.

If you do not want to create a new array and want the new array to refer to the existing array in the $oldArray you can do:

$newArray = &$oldArray[0];

Any changes made to $newArray will also change $oldArray in this case.

See this it may useful for you,

$sss = array () ;
$sss['sadness']['info'] = "some info";
$sss['sadness']['info2'] = "more info";
$sss['sadness']['value'] = "value";
$sss['happiness']['info'] = "some info";
$sss['happiness']['info2'] = "more info";
$sss['happiness']['value'] = "value";
$sss['peace']['info'] = "some info";
$sss['peace']['info2'] = "more info";
$sss['peace']['value'] = "value";

print_r($sss['sadness']);
echo "<br>";

print_r($sss);
echo "<br>";

Output 1 :

Array ( [info] => some info [info2] => more info [value] => value )

Output 2 :

Array ( [sadness] => Array ( [info] => some info [info2] => more info [value] => value ) [happiness] => Array ( [info] => some info [info2] => more info [value] => value ) [peace] => Array ( [info] => some info [info2] => more info [value] => value ) )
