PHP Limit letters in the result

Question

How do I limit the amount of letters that will appear in <?= $v['titulo']?> within the <div class="col-md-4 panel">

I’ve tried a lot of things, but it’s a mistake.

<?php $result = selectAllAnuncios(1,18); foreach ($result as $k => $v):
    $link = "anuncio,".$v['id'].",".str_replace(" ","-",$v['titulo'])."-".str_replace(" ","-",$v['ano']);
    $image  = (@is_file("img/anuncios/".$v["imgs"][0]["name"])) ? "img/anuncios/".$v["imgs"][0]["name"] : "img/no-img.jpg" ; ?>

    <div class="col-md-4 panel ">
        <a href="<?=$link?>"> <img src='<?=$image?>' width="200" height="100">
        <div ><?=$v['titulo'] ?> </br> <?=$v['ano']?> - R$ <?=$v['preco']?>   
            </a>
        </div>
    </div>

    <?php endforeach; ?>

If you are going to limit the characters, you can use the substr of PHP itself. As follows:

<?php $result = selectAllAnuncios(1,18); foreach ($result as $k => $v):
    $link = "anuncio,".$v['id'].",".str_replace(" ","-",$v['titulo'])."-".str_replace(" ","-",$v['ano']);
    $image  = (@is_file("img/anuncios/".$v["imgs"][0]["name"])) ? "img/anuncios/".$v["imgs"][0]["name"] : "img/no-img.jpg" ; ?>

    <div class="col-md-4 panel ">
        <a href="<?=$link?>"> <img src='<?=$image?>' width="200" height="100">
        <div ><?=substr($v['titulo'], 0, 10)."..."; ?> </br> <?=$v['ano']?> - R$ <?=$v['preco']?>   
            </a>
        </div>
    </div>

    <?php endforeach; ?>

substr($v['titulo'], 0, 10)."...";

In this case, 0 is the starting point and 10 is the number of characters to be read.

As suggested by Wallace, you can use the m_substr function as follows:

mb_substr($v['titulo'], 0, 10,'UTF-8');

Then passing the UTF-8 so there are no problems with special characters.
