Question

I need to split this kind of strings to separate the email between less and greater than < >. Im trying with the next regex and preg_split, but I does not works.

"[e-mail]" <[e-mail]>
News <[e-mail]>
Some Stuff <[e-mail]>

The expected result will be:

Array
(
    [0] => "[e-mail]"
    [1] => [e-mail]
)
Array
(
    [0] => News
    [1] => [e-mail]
)
Array
(
    [0] => Some Stuff
    [1] => [e-mail]
)

Code that I am using now:

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

You may use some of the flags available for preg_split: PREG_SPLIT_DELIM_CAPTURE and PREG_SPLIT_NO_EMPTY.

$emails = array('"[e-mail]" <[e-mail]>', 'News <[e-mail]>', 'Some Stuff <[e-mail]>');

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

This outputs what you expect:

Array
(
    [0] => "[e-mail]" 
    [1] => [e-mail]
)
Array
(
    [0] => News 
    [1] => [e-mail]
)
Array
(
    [0] => Some Stuff 
    [1] => [e-mail]
)
