我在php中有这个代码:
<?php
$mails_list = "user1@example.com, User 2 <user2@example.com>, User 3 (user3@example.com)";
$mails_arr = explode(',', $mails_list);
foreach($mails_arr as $mail){
echo "{$mail}<br>";
}
?>
请注意,使用该代码,他的输出将为:
user1@example.com
User 2 <user2@example.com>
User 3 (user3@example.com)
我不想那样。我想要的是输出必须是:
user1@example.com
user2@example.com
user3@example.com
我怎么能用PHP做到这一点?

您可以使用preg_match_all()
使用正则表达式捕获所有电子邮件:
preg_match_all('/[<(]?(\w+@\w+\.\w+)[>)]?/', $mails_list, $matches);
echo implode("\n", $matches[1]);

你走了,
<?php
$mails_list = "user1@example.com, User 2 <user2@example.com>, User 3 (user3@example.com)";
$mails_arr = explode(',', $mails_list);
preg_match_all('/[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,4}/i', $mails_list, $found_mails);
foreach ($found_mails[0] as $each) { echo $each.'<br>'; }
