Question

I have to get any text between:

Final-Recipient: RFC822; !HERE! Action

I need !HERE! from this example. There could be any string.

I tried something like:

$Pattern = '/Final-Recipient: RFC822; (.*) Action/';

But it doesn’t work.

upd

Here is the string I’m trying to parse: http://dpaste.com/187638/

Your pattern works fine for me:

$i = 'This is a MIME-encapsulated message --o3ONXoEH01blah3:35:33 +0400 (MSD) Final-Recipient: RFC822; !HERE! Action: failed Status: 4.4.7 Lblahru> From: *
@*.ru';    
$pattern = '/Final-Recipient: RFC822; (.*) Action/';
$matches = Array();
preg_match($pattern, $i, $matches);
print_r($matches);

Output:

Array
(
    [0] => Final-Recipient: RFC822; !HERE! Action
    [1] => !HERE!
)

Note also that your pattern will fail if the “any text” contains new lines. Use the DOTALL modifier /.../s to allow the dot to also match new lines. Also note that if the text ” Action” appears elsewhere in the message it will cause your regular expression to fail. Matching dot is dangerous. Try to find a more specific pattern if possible.
