问题描述
我想从PHP中的字符串中解析货币,所以我看过数字格式化器但没有PHP 5.3或添加扩展的功能.
I want to parse a currency from a string in PHP, I've had a look at number formatter but haven't got PHP 5.3 or the ability to add extensions.
该货币每个字符串仅存在一次,并且将以货币符号作为前缀,在本例中为英镑符号£.货币可以采用以下格式之一:
The currency will only exist once per string, and will be prefixed with a currency symbol, in my case the pound sign £. The currency may be in one of the following formats:
£0.90
£100
£100.10
£1000
实现此目标的最佳方法是什么?
What would be the best method of achieving this?
修改
这是一个示例字符串:
Paid a bill £153.93
我想将货币值转换为变量.
I want to get the currency value into an variable.
推荐答案
(float)substr($input, strpos($input, "£")+1);
这将为您带来以下结果:
This will get you the following results:
float(0.9)
float(100)
float(100.1)
float(1000)
float(153.93)
编辑:已更新,以反映对问题的更改.假设所有字符串都像您作为示例给出的那样.
EDIT: updated to reflect the change to question. this is assuming all strings are like the one you gave as an example.
