与php中的foreach混淆[关闭]

Question

I having some trouble with a loop in php. It's with the foreach loop. I have this code:

<?php foreach($obras as $obra): ?>
    <li>
        <a class="thumb" href="<?php echo $base_url . 'assets/uploads/files/' . $obra["imagen"] ?>" title="<?php echo $obra['titulo'] ?>">
            <img src="<?php echo $base_url . 'assets/uploads/files/' . $obra["imagen"] ?>" alt="<?php echo $obra['titulo'] ?>" />
        </a>
        <div class="caption">
            <div class="image-desc">

                <p><?= t('global_pieces_artist')?>: <?php echo $obra['nombre_artista'] . ' ' . $obra['apellidos_artista'] ?></p>
                <p><?= t('global_pieces_title')?>: <?php echo $obra['titulo'] ?></p>
                <p><?= t('global_pieces_year')?>: <?php echo $obra['ano'] ?></p>
                <p><?= t('global_pieces_size')?> (cm.): <?php echo $obra['tamano_alto'] ?> x <?php echo $obra['tamano_ancho'] ?><? if ($obra['tamano_largo'] != null): ?> x <?php echo $obra['tamano_largo'] ?><? endif; ?></p>
                <p><?= t('global_pieces_technique')?>: <?php echo $obra['tecnica'] ?> </p>

                <? if (isset($obra['username'])): ?>
                    <p><?= t('global_company') ?>: <?php= echo $obra['username'] ?></p>
                <? endif; ?>

                <p><?= t('global_pieces_price')?>: <?php echo ($obra['precio'] . ' ' . $obra['divisa']) ?> (<?= t('global_pieces_price_vat')?>)</p>

                <? if ($obra['observaciones'] != null): ?>
                    <p><?= t('global_pieces_observations')?>: <?php echo $obra['observaciones'] ?></p>
                <? endif; ?>

                <p id="links_last">
                    <a href="<?php echo $base_url . 'assets/uploads/files/' . $obra['imagen']?>"><?= t('global_download')?></a> |
                    <a href="javascript:window.print();"><?= t('global_print')?></a>
                </p>
            </div>
        </div>
    </li>
<?php endforeach; ?>

Well, all things which I want to print are ok, but when I arrive to this part of the code:

<? if (isset($obra['username'])): ?>
    <p><?= t('global_company') ?>: <?php= echo $obra['username'] ?></p>
<? endif; ?>

It's when I have the problem because I can see the left side of what I want to see which is the content of <?= t('global_company') ?> and what it is on the right side I can't see it. If I remove the = then I have an error, so what I'm doing bad.

Thanks in advance.

Quoting your code...

<p><?= t('global_company') ?>: <?php= echo $obra['username'] ?></p>

The second echo isn't valid. You can use <?= or <?php echo but not <?php= echo

Change the line I quoted above to

<p><?= t('global_company') ?>: <?= $obra['username'] ?></p>

and you should get what you're after
