PHP: Textbox Separate Emails PHP:Textbox单独的电子邮件
I am attempting to separate multiple email addresses that are being entered into a textbox. 我正在尝试将正在输入的多个电子邮件地址分隔到文本框中。 My problem is that if I use the advice from above:
我的问题是如果我使用上面的建议:
$emails = preg_split('/[;,\n]/', $_POST['email_receivers']);
It works great only if there is no space after the delimiter. 只有在分隔符后面没有空格时才能正常工作。 How can I adjust this so that someone can separate email addresses by either just the delimiter or the delimiter plus a space.
我如何调整此值,以便有人可以通过分隔符或分隔符加空格来分隔电子邮件地址。
eg. 例如。 (
email1@xyz.com;email2@xyz.com
) AND ( email1@xyz.com; email2@xyz.com
) should both work but currently only the first example works. (
email1@xyz.com;email2@xyz.com
)和( email1@xyz.com; email2@xyz.com
)应该都可以,但目前只有第一个例子有效。
I'd like to improve Michael Berkowski's answer by making the spaces optional: 我想通过使空格可选来改进Michael Berkowski的答案:
$emails = preg_split('/\s*[;,\n]\s*/', $_POST['email_receivers']);
\\s+
requires one or more spaces. \\s+
需要一个或多个空格。 \\s*
makes them optional (zero or more) \\s*
使它们可选(零或更多)
