正则表达式从字符串中删除ID = 1234（PHP）(regular expression to remove ID=1234 from a string (PHP))

正则表达式从字符串中删除ID = 1234（PHP）(regular expression to remove ID=1234 from a string (PHP))

我正在尝试创建一个正则表达式来执行以下操作（在preg_replace中）

$str = 'http://www.site.com&ID=1620'; $str = 'http://www.site.com';

如何编写preg_replace来简单地从字符串中删除＆ID = 1620（考虑到ID可能是变量字符串长度

提前致谢

I am trying to create a regular expression to do the following (within a preg_replace)

$str = 'http://www.site.com&ID=1620'; $str = 'http://www.site.com';

How would I write a preg_replace to simply remove the &ID=1620 from the string (taking into account the ID could be variable string length

thanks in advance

你可以用......

$str = preg_replace('/[?&;]ID=\d+/', '', $str);

我假设这是一个普通的URL，因此[?&;] 。 如果是这样的话， &应该是? 。

如果它是更大的GET参数列表的一部分，你可能最好使用...

parse_str($str, $params); unset($params['ID']); $str = http_build_query($params);

You could use...

$str = preg_replace('/[?&;]ID=\d+/', '', $str);

I'm assuming this is meant to be a normal URL, hence the [?&;]. If that's the case, the & should be a ?.

If it's part of a larger list of GET params, you are probably better off using...

parse_str($str, $params); unset($params['ID']); $str = http_build_query($params);
