如何在任何页面上显示OpenCart上的SubTotal - How can I display the SubTotal on OpenCart on any page?

How can I display the SubTotal on OpenCart on any page?

目前我所知道的唯一全局PHP命令是：

<?=$text_items?>

这唾沫：

1 item(s) - £318.75

我想得到318.75的值，所以目前我正在尝试更换，但工作并不顺利：

$short = $text_items;
$short = str_replace("£", "", $short);
$short = str_replace("&pound;", "", $short);
$short = str_replace("-", "", $short);
$short = str_replace("&ndash;", "", $short);
$short = str_replace(" ", "", $short);
$short = str_replace("-", "", $short);
$short = str_replace("ITEMS", "", $short);
$short = str_replace("(", "", $short);
$short = str_replace(")", "", $short);
$short = str_replace("item(s)", "", $short);
$short = str_replace("ITEM", "", $short);

$total = @floatval(end(explode('£', html_entity_decode($text_items))));

html_entity_decode将£更改为£
end(explode('£'在"£"字符后为您提供字符串
最后CCD_ 7将字符串赋值为float
@绕过了CCD_ 9函数中传递常数时出现的CCD_

工作示例

第二个解决方案是Regexp:

preg_match_all('!'d+(?:'.'d+)?!', $text_items, $result);
echo $result[1];
