Question

I’d like to list/group words by the first two letters but I can’t get my head around it. I guess I can I can do a substr() and check against while looping but I’m not sure if this is the way to do it.

Something like:

if (substr($word, 0, 2) == 'aa') {
 echo $word;
}

What I’m trying to achieve:
Words get sorted first by their starting letter, e.g. A, B, C etc. On the A page you have the words sorted by the first 2 letters, e.g. aa, ab, ac etc.

An example for this is http://www.urbandictionary.com/browse.php?word=aa. They do exactly what I’m after.

Help/thoughts appreciated!

If you have a bunch of words, put them grouped together in an array.

for example:

<?php
$myWords = array ("hello", "hell", "ape", "word", "appel");
$myGroupedArr = array();
foreach ($myWords as $oneWord){
  $firstTwo = substr($oneWord,0,2);
  $myGroupedArr[$firstTwo][] = $oneWord;  
}
echo "<pre>";
print_r($myGroupedArr);
echo "</pre>";
?>
