Not realy the very best solution to use strpos and substr. You'll
have to loop through the "From-string" and look for the next address
each time. You can have more than one address in the From-field! And
then again... what would you do with addresses that are not between
< and >? Eg.: Renze Munnik <[EMAIL PROTECTED]>, [EMAIL PROTECTED]
Using strpos and substr won't realy make you're live any simpler.
I suggest you use something like the following RE:
$emlchars = "[a-z0-9.-]+";
$RE = "/($emlchars@$emlchars)/i";
I've put the allowed characters for the email-address in a separate
string in order to make it read easier. You can add all characters
to that string that are also allowed, because I don't believe these
are the only allowed characters in an email-address.
How to use? See the following example code:
--- PHP Code ---
<PRE>
<?php
$from = "* R&zE: <[EMAIL PROTECTED]>,
[EMAIL PROTECTED],
Mr Nobody <[EMAIL PROTECTED]>";
$emlchars = "[a-z0-9.-]+";
$RE = "/($emlchars@$emlchars)/i";
if (preg_match_all ($RE, $from, $matches)) {
print ("<H1>Matched!</H1>\n\n");
print_r ($matches);
} else {
print ("<H1>Didn't match!</H1>");
}
?>
</PRE>
--- End of PHP Code ---
