php - 在小于和大于之间拆分字符串

Question

我需要拆分这种字符串以将电子邮件分隔为小于和大于 < >。我正在尝试使用下一个 regex 和 preg_split，但我不工作。

"email1@domain.com" <email1@domain.com>
News <news@e.domain.com>
Some Stuff <email-noreply@somestuff.com>

预期结果将是:

Array
(
    [0] => "email1@domain.com"
    [1] => email@email.com
)
Array
(
    [0] => News
    [1] => news@e.domain.com
)
Array
(
    [0] => Some Stuff
    [1] => email-noreply@somestuff.com
)

我现在使用的代码:

foreach ($emails as $email)
{
   $pattern = '/<(.*?)>/';
   $result = preg_split($pattern, $email);
   print_r($result);
}

Answer 1

您可以使用一些可用于 preg_split 的标志: PREG_SPLIT_DELIM_CAPTURE 和 PREG_SPLIT_NO_EMPTY。

$emails = array('"email1@domain.com" <email1@domain.com>', 'News <news@e.domain.com>', 'Some Stuff <email-noreply@somestuff.com>');

foreach ($emails as $email)
{
    $pattern = '/<(.*?)>/';
    $result = preg_split($pattern, $email, -1, PREG_SPLIT_DELIM_CAPTURE | PREG_SPLIT_NO_EMPTY);
    print_r($result);
}

这会输出您所期望的:

Array
(
    [0] => "email1@domain.com" 
    [1] => email1@domain.com
)
Array
(
    [0] => News 
    [1] => news@e.domain.com
)
Array
(
    [0] => Some Stuff 
    [1] => email-noreply@somestuff.com
)
