使用array的next（）不打印正确的值

Question

If I have this data, how to get current & next array value based on specific key

$data = array(
                array(
                    "name"=>"Joseph",
                    "location"=>"Wisconsin"
                ),
                array(
                    "name"=>"Sally",
                    "location"=>"Toronto"
                )
            );

This is how I am doing it, but seems to not displaying what I expect it to be. Kindly assist.

foreach ($data as $val)
{
    echo 'current:'.$val['name'].'<br/>';

    $nextval = next($val);
    echo 'next:'.$nextval['name'].'<br/>';
}

This is what is being printed out

current:Joseph
next:W
current:Sally
next:T

I expect it to be

current:Joseph
next:Sally
current:Sally
next:[..next value..]

Change your foreach loop to this:

foreach ($data as $key=>$val)
{
    echo 'current:'.$val['name'].'<br/>';
    $nextval = $data[$key+1];
    echo 'next:'.$nextval['name'].'<br/>';
}

It has the behavior you asked for.
