next() and prev() position with array function php

I have a code below,

<?php
$people = array("patrick", "wumbo", "wambo", "Peter", "Joe", "Glenn", "Cleveland");

echo current($people) . "<br>";
echo next($people) . "<br>";
echo prev($people);
?>

my question is if I want current position is "joe", how to show my all previous position and my all next position ?

output:

my prev = *patrick wumbo wambo Peter*

my next = *Glenn Cleveland*

update question

<?php
$a = "My brother see the moon";
$b = explode(" ",preg_replace("/(\.|\"|,|;|\(|\)|'|)+?/i","",$a));
for($ulangKata=0;$ulangKata<count($b);$ulangKata++)
            {
            $huruf_kecil = strtolower($a);
            $fungsi_replace = preg_replace("/(\.|\"|,|;|\(|\)|'|)+?/i","",$huruf_kecil);
            $pecah_untuk_kata = explode(" ",$fungsi_replace);
            $pecah_kata = $pecah_untuk_kata[$ulangKata];
            echo "kata ke - ".$ulangKata." ".$b[$ulangKata]."<br>"; 
            }
            echo "<br>";
            for($ulangKata=0;$ulangKata<count($b);$ulangKata++)
            {
            echo $b[$ulangKata]."<br>";
            }
?>

and I want see the output like

Subject : My brother
Predicate : see
Object : the moon

I have already trying but have no idea since last night.

Something like this?

    $current= "Joe";

    $people = array("patrick", "wumbo", "wambo", "Peter", "Joe", "Glenn", "Cleveland");
    $pos    = array_search($current, $people);

    foreach($people as $key => $value) {

        if($key < $pos) {

            $prev[] = $value;

        } elseif($key > $pos) {

            $next[] = $value;

        }

    }

    foreach($prev as $item) {
        echo "$item ";
    }
    echo "<br />";
    foreach($next as $item) {
        echo "$item ";
    }

Output:

patrick wumbo wambo Peter 
Glenn Cleveland

UPDATE 2

<?php

        function getSubObj($string, $verb) {

            $parts  = explode(" ", $string);
            $pos    = array_search($verb, $parts);

            foreach($parts as $key => $value) {

                if($key < $pos) {

                    $subjects[] = $value;

                } elseif($key > $pos) {

                    $objects[]  = $value;

                }

            }

            return array($subjects, $objects);

        }

        list($subjects, $objects) = getSubObj("Brother see the moon", "see");

        echo "<h2>Subjects</h2>";
        foreach($subjects as $item) {
            echo "$item ";
        }

        echo "<h2>Objects</h2>";
        foreach($objects as $item) {
            echo "$item ";
        }


?>

Output:

Thank's all for your support,

Hmm if I have a String like below

$text = "Brother see the moon";

I sign to my code that "see" as verb,

all array before "see" as subject

and all array after "see" as object

make it easy by array_slice

$key=array_search("Joe",$people);
echo "Current:".$people[$key] . "\n" .
     "Prev:".implode(",", array_slice($people, 0, $key)) . "\n" .
     "Next:".implode(",", array_slice($people, $key+1));

Try this...

<?php
$people = array("patrick", "wumbo", "wambo", "Peter", "Joe", "Glenn", "Cleveland");


$key=array_search("Joe",$people);
$next=array();
$prev=array();
for($i=$key+1;$i<count($people);$i++)
{
$next[]=$people[$i];
}

for($i=$key-1;$i >0;$i--)
{
$prev[]=$people[$i];
}

echo "Current:".$people[$key];
 echo "</br>";
echo "Next:".implode(",",$next);
 echo "</br>";
echo "prev:".implode(",",$prev);
?>

Result:

Current:Joe
Next:Glenn,Cleveland
prev:Peter,wambo wumbo
