如何在switch case中回显PHP代码
问题描述：
So I have this code that should display price in one case and "Paid" text in other:
<?php
switch($order['status'])
{
case 0:
echo
'<div class="paiment">
<p>Some text</p>
<ul>
<li>More text</li>
<li>More text</li>
<li>Important text:
<?php foreach($something as $item): ?>
<?php
$unitPrice = HelperItem::displayItemPrice($item["price"], true, $configuration);
?>
<?php echo $unitPrice; ?>
<?php endforeach; ?>
</li>
</ul>
</div>'
;
break;
case 1:
echo 'Paid';
break;
}
?>
I need some way to make this "foreach" work inside "echo". I've tried with removing "" and doing something like this: echo 'xxxx' . code . 'xxxx' but all I got was errors. Is it even possible to make this work?

You're very close, just need to break things up around the foreach:
<?php
switch($order['status'])
{
case 0:
echo
'<div class="paiment">
<p>Some text</p>
<ul>
<li>More text</li>
<li>More text</li>
<li>Important text:';
foreach($something as $item)
echo HelperItem::displayItemPrice($item["price"], true, $configuration);
echo '</li>
</ul>
</div>'
;
break;
case 1:
echo 'Paid';
break;
}
?>
答
You cannot echo a foreach. Maybe try something like:
echo "xxxx";
foreach(){ }
echo "xxxx";
