Question

I have an array

$foo = array(1,2,3,4,5,6,7,8,9); 

when I use foreach loop for this

foreach($foo as $val):  
    print '<li>'.$val.'</li>';  
endforeach 

Out put is ,

<li> 1 </li>  
<li> 2 </li>  
<li> 3 </li>  
<li> 4 </li>  
<li> 5 </li>

But I want out put something like that

<li> 1, 2 </li>  
<li> 3, 4 </li>  
<li> 5, 6 </li>  
<li> 7, 8 </li>  

Is it possible?

This might be what you require:

foreach($foo as $key=>$val) {
    if ($val&1) {
        echo '<li>' . $val;
        if($key == (count($foo)-1)){
            echo '</li>';
        }
    } else {
        echo ',' . $val . '</li>';
    }
}
