<?php
if ( ($cart->count_product) > 0) {
print $cart->count_product;
} else {
print '';
}
?>
and i need to put print $cart->count_productinside of <div class="my_class"></div>
我需要把print $cart->count_product里面<div class="my_class"></div>
I tried different ways, but i'm missing something in syntax. I'll be glad if someone could help.
我尝试了不同的方法，但我在语法上遗漏了一些东西。如果有人可以提供帮助，我会很高兴。

You can do the following:
您可以执行以下操作：
echo '<div class="my_class">';
echo ($cart->count_product > 0) ? $cart->count_product : '';
echo '</div>';
If you want to have it inside your statement, do this:
如果您想将其包含在您的语句中，请执行以下操作：
if($cart->count_product > 0)
{
echo '<div class="my_class">'.$cart->count_product.'</div>';
}
You don't need the elsestatement, since you're only going to output the above when it's truthy anyway.
您不需要该else语句，因为无论如何您只会在它为真时输出上述内容。

Try this,
尝试这个，
<?php if ( ($cart->count_product) > 0) { ?>
<div class="my_class"><?php print $cart->count_product; ?></div>
<?php } else {
print '';
} ?>

Just wrap it around then.
那就把它包起来吧。
<?php
if ( ($cart->count_product) > 0)
{
echo "<div class='my_class'>";
print $cart->count_product;
echo "</div>";
}
?>

You can do this:
你可以这样做：
<div class"my_class">
<?php if ($cart->count_product > 0) {
print $cart->count_product;
} else {
print '';
}
?>
</div>
Before hitting the div, we are not in PHP tags
在点击 之前div，我们不在 PHP 标签中

You can also do this,
你也可以这样做，
<?php
if ( ($cart->count_product) > 0) {
$print .= "<div class='my_class'>"
$print .= $cart->count_product;
$print .= "</div>"
} else {
$print = '';
}
echo $print;
?>

You can use the below sample, also you dont need the else clause to print nothing!
您可以使用以下示例，也不需要 else 子句来打印任何内容！
<?php if ( ($cart->count_product) > 0) { ?>
<div class="my_class">
<?php print $cart->count_product; ?>
</div>
<?php } ?>
