Question

Let’s say I have this foreach loop:

foreach ($lists as $list) {
    if (next list item == "test") {
         echo "the next $list item equals 'test'";
    }
}

I hope you get what i’m aiming at from the code.

Thanks,

You can use next().

Bear in mind this advances the internal pointer, so to rewind it back, use prev().

However, in the example below, I used current() which gets the current pointer of an array. foreach() seems to increment it once in the body of the construct.

Konforce came up with this idea originally.

The last blank is NULL, which is good (there is no next member). 🙂

$lists = range('a', 'f');

foreach($lists as &$value) {
   $next = current($lists);
   echo 'value: ' . $value . "\n" . 'next: ' . $next . "\n\n";
}

unset($next, $value);

Output

value: a
next: b

value: b
next: c

value: c
next: d

value: d
next: e

value: e
next: f

value: f
next:
