带有字母标题的列表

Question

How can i extend the list with alphabetical headings. For Example:

A Anchor Animal

B Bus Burn

E Eat Euro

This is my actually Code:

    <ol class="items brand-items">
        <?php foreach ($block->getBrands() as $brand): ?>
            <li class="item brand-item">
                <?php echo $block->escapeHtml($brand->getName()) ?>
            </li>
        <?php endforeach; ?>
    </ol>

Answer 1

assuming your inputs as :

$list = ['apple', 'and', 'another', 'ball', 'bat', 'cat', 'call'];

and your desired output be:

Array (
    [a] => Array
        (
            [0] => apple
            [1] => and
            [2] => another
        )

    [b] => Array
        (
            [0] => ball
            [1] => bat
        )

    [c] => Array
        (
            [0] => cat
            [1] => call
        )

)

you ought to do something like:

$out = [];

foreach ($list as $brand) {
  $out[substr($brand,0,1)][] = $brand;

}

print_r($out);
