@Rahuljuneja-DevOps i need to rotate array to left or right ... it's not simple sort — UFO, Oct 27 '20 at 14:04
Include sample data like let's say searching for email `joe@domain.com` what should be output. — Dark Knight, Oct 27 '20 at 14:14

It seems everything work fine ... Is it right ???

$arr = Array(
Array('email' => "0@domain.com"),
Array('email' => "1@domain.com"),
Array('email' => "2@domain.com"),
);

while($arr[sizeof($arr)-1]['email'] != "1@domain.com" )
{
    array_push($arr, array_shift($arr));
}

echo "<pre>";
print_r($arr);
echo "<pre>";
