Answer 1

Try this use the array_shift and run the loop two times.
Note: Read the comment in the answer as i explain there why i wrote it this way.
<?php
$string = "hi hello how are you hope you";
$exp = explode(" ",$string);
for ($i=0; $i<(count($exp)+3);$i++)//as you want to print three value in
//each loop your loop should run three more time than
//the number of element you got in your original array
{
echo '<br/>';
for($k=0;$k<3;$k++)
{
echo ' ';//added the space to see
print_r($exp[$k]);//to see the result
}
$value= array_shift($exp);//after printing the result remove the
//first element from the array. so this will remove the first elemenet after
//each result.
}
Your Result will look like this
hi hello how
hello how are
how are you
are you hope
you hope you

This code sample give 2 levels .No of foreach is the no of words.
$vari = "hai hello how?";
$vari = str_replace("?", "", $vari);
$vars = explode(" ", $vari);
$varp = $vars;
foreach ($vars as $p_i=>$p_v){
foreach($varp as $c_i=>$c_v){
if($p_i!=$c_i){
echo $p_v." ".$c_v."<br/>";
}
}
}
RESULT
hai hello
hai how
hello hai
hello how
how hai
how hello
You can put foreach inside another foreach to get more words.
