我无法从Woocommerce购物车总计中获得美元符号以从价值中剥离

我已经尝试了下面代码的所有变体，并将其添加到我的email-order-details.php文件中。他们中没有一个能正常工作。 $ totalVal会保留附加的美元符号，或者$ totalVal打印为0。当$ totalVal打印为0时，我的if语句仍然打印。不管if比较器如何打印。我实际上是将更改上传到Web服务器，然后重新发送电子邮件。我可以使其在test.php文件中工作。好吧，我可以使它不回显该语句，但不能使它去除美元符号。

<div><?php
        $strpTotal = $total['value'];
        $totalVal = floatval(ltrim($strpTotal, "$"));
        if ( $totalVal < 100 ){
                        echo 'My Text';}
                     ?></div>


<div><?php 
        $strpTotal = trim($total['value'], "$");
        if ( $strpTotal < 100 ){
                        echo 'My Text';}
                ?></div>


<div><?php 
        $strpTotal = $total['value'];
        $totalVal = trim($strpTotal, "$");
        if ( $totalVal < 100 ){
                        echo 'My Text';}
                ?></div>

下面的整个文件代码

我想在woocommerce电子邮件中使用条件PHP if语句。我的代码应获得购物车总额，并从中扣除$。然后比较一下，如果购物车总数少于100，请确保购物车总数少于100，我的对帐单应打印出来。请所有帮助表示赞赏。

因此，感谢@anyber preg_replace（“ / [^ 0-9 .-] /”，''，$ strpTotal）;工作了。我必须将[^ 0-9.-]更改为代表HTML中美元符号的$。在未说任何内容之前，我确实尝试过使用此方法和上面的ltlt rimrim和floatval序列。我确实尝试过一次pre_replace，但是不了解/ [^ 0-9，-] /部分，并且我最初使用它的尝试都没有用，所以我尝试使用我理解得更好的命令。如果@anyber希望在此处张贴答案作为答案，我将很乐意为他们提供功劳。
