从字符串中删除英镑符号 [英] Stripping the Pound sign from a string

问题描述

大家好，

我的HTML文档中有一个表单，要求用户输入商品的PRICE，并且该表单由PHP发布.

要发布的字符串的格式为:0.00英镑，或00.00英镑，000.00英镑等.

基本上，我试图剥离英镑符号，但保留小数点，这样它就可以进入我的sql数据库中.

有没有解决此问题的简单方法?我尝试使用 mysql_real_escape_string 和 str_replace ，但是它不适合我！

任何评论和答案都将不胜感激.

汤姆，敬上.

解决方案

如果字符串具有 始终 格式，然后看看这个:

http://php.net/manual/en/function.substr.php [ ^ ]

通过这种操作，您可以始终删除任何字符串中的第一个字符...

如果字符串 t始终不具有 格式，请查看以下内容:

如果 http://php.net/manual/en/function.str-replace.php [ ^ ]不适用于您. ..

然后，您可以查看正则表达式:

http://php.net/manual/en/function.preg-match.php [ ^ ]

Hi everyone,

I have a form on my HTML document that requires the user to type in a PRICE for an item, and it is POSTED by PHP.

The format of the string that is being posted is: £0.00, or £00.00, £000.00 etc.

Basically I''m trying to strip away the Pound Sign but keep the decimal place, so that it goes in my sql database OK.

Is there an easy way around this? I tried using mysql_real_escape_string and str_replace but it doesnt want to work for me!!

Any comments and answers are greatly appreciated.

Regards, Tom.

解决方案

If the string has always that format, then take a look at this:

http://php.net/manual/en/function.substr.php[^]

With this kind of operation you could remove the first char always in any string...

If the string doesn''t has always that format, then take a look at this:

If http://php.net/manual/en/function.str-replace.php[^] is not working for you...

Then you could look at regular expressions:

http://php.net/manual/en/function.preg-match.php[^]

hope this helps...
