多语言网站,需要提取$299.00,其中$不确定,因为有可能是¥,£等符号,
可以确定的是$299.00前都包含一个空格,小数点后都有两位数,
换句话说,需要从:
<code>您的账户有未付账单金额 $299.00,请尽快完成付款。</code>
或者
<code>Your account has an outstanding balance of $299.00. Please make a payment at your earliest convenience.</code>
提取到$299.00。
中文显示:

从代码来看,这段代码的内容除了名称和金额之外其他的应该是不变的内容,这样的话就比较好办了。
直接去匹配金额/\s(.\d+\.\d{2})/g就是了,前提是针对该段代码,如果是整个页面的话,需要把匹配局限到这段代码中来。。

不知道题主的目的,提取这个金额做何用,是要去进行支付吗?如果是支付,这个金额不应该去服务端验证吗?毕竟这个价格前端可以篡改。
如果只是仅仅需要匹配的话,可以使用这个表达式
<code>$pattern = '#([\$|¥|£][1-9][0-9]*.[0-9]{2})#'; // $subject = '您的账户有未付账单金额 $299.00,请尽快完成付款。'; $subject = 'Your account has an outstanding balance of $299.00. Please make a payment at your earliest convenience.'; preg_match($pattern, $subject, $a); var_dump($a); // 输出: array(2) { [0] => string(7) "$299.00" [1] => string(7) "$299.00" }</code>
汗颜,不知道为什么变成了两个?原因不明

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3.
