问题描述
我有一个 HTML 表单字段 $_POST["url"]，有一些 URL 字符串作为值.
示例值为:
https://example.com/test/[email protected]://example.com/test/[email protected]://example.com/test/[email protected]://example.com/test/[email protected]&testin=123https://example.com/test/the-page-here/[email protected]等
如何才能从这些 URL/值中只获取 email 参数?
请注意，我不是从浏览器地址栏中获取这些字符串的.
解决方案
您可以使用 parse_url() 和 parse_str() 为此.
$parts = parse_url($url);parse_str($parts['query'], $query);回声 $query['email'];如果你想用PHP动态获取$url，看看这个问题:

etc.
How can I get only the email parameter from these URLs/values?
Please note that I am not getting these strings from the browser address bar.

$parts = parse_url($url);
parse_str($parts['query'], $query);
echo $query['email'];
