Echoing Array in an A-Z List

Question

Say I have the following array:

$aTest = array('apple', 'pear', 'banana', 'kiwi', 'pineapple', 'strawberry');

I need to be able to create a list from A-Z and show the relevant values from the array under each letter. E.g A - Apple, B - Banana, C - empty, D - empty, ... K - Kiwi .. P - Pear, Pineapple etc.

Can someone please help me? I assume I loop from A-Z using range but then im not sure how to echo out the relevant value from the array(and also in alphabetical order within each letter i.e pear before pineapple)

Thanks

Through the use of conditionals and some built-in functions; this code is a little rough, but it does the trick:

<?php
    $aTest=array('apple','pear','banana','kiwi','pineapple','strawberry');
    $len=(count($aTest)-1);
    $letters=array('a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','x','y','z');
    $str=null;
    foreach($letters as $letter) {
        for($i=0;$i<=$len;$i++) {
            $str=strtoupper($letter).' - ';
            if(strtolower(substr($aTest[$i],0,1))==strtolower($letter)) {
                $str.=$aTest[$i];
                break;
            } elseif($i==$len) {
                $str.='empty';
            }
        }
        echo($str.'<br />');
    }
?>
