How to sort snippet array alphabetically?

We're using Jakoweb / AlanPich Modx Extra Glossary. It generates a nice front end page with A, B, C ... navigation which then link to a bunch of Glossary terms and explanations beginning with that letter. Only thing is, under each letter the terms are themselves not in alphabetical order, e.g:
C
Crocodile
Cat
Camel
Crayfish

We want
C
Camel
Cat
Crayfish
Crocodile

The terms per letter are all output to an [[+items]] placeholder. This seems to be set using the content of a $termsHTML variable:

[// Output all terms (grouped)
$groupsHTML = '';
foreach ($letters as $letter => $terms) {
    $termsHTML = '';
    if (count($terms)) {
             // Prepare Terms HTML
        foreach ($terms as $term) {
            $params = array_merge($term, array(
                'anchor' => strtolower(str_replace(' ', '-', $term['term'])),
                'letter' => $letter
            ));
            $termsHTML .= $modx->getChunk($termTpl, $params);
        };
        // Prepare letter wrapper HTML
        $groupsHTML .= $modx->getChunk($groupTpl, array(
            'items' => $termsHTML,
            'letter' => $letter
        ));
    };
};

The actual page within the manager IS output alphabetically. Would anyone have any idea how to sort the $termsHTML? Tried KSort but that didn't work. [ed. note: lancipoos last edited this post 5 years, 6 months ago.]

What does the each $terms array look like? Can you show at least the beginnings of one:

return "<pre>" . print_r($terms, true) . "</pre>";

Sure

<pre>Array
(
    [0] => Array
        (
            [id] => 39
            [term] => Term Title
            [explanation] => An internationally agreed description of what this term is.
            [modified] => 2018-07-18 11:40:36
            [modified_by] => 0
        )

)
</pre>

Can you modify your code so the array looks like this:

Array
(
    [term] => Array
        (
            [id] => 39
            [term] => Term Title
            [explanation] => An internationally agreed description of what this term is.
            [modified] => 2018-07-18 11:40:36
            [modified_by] => 0
        )
 
)

Then ksort() should work on it. If you can't modify the array, you can write your own compare function that looks at $key['term'] and uses one of the "user-defined" sorting functions here: http://php.net/manual/en/array.sorting.php.
