What do you mean by, "i need to use $matches[0] and $matches[1]?" $matches[0] should be the whole match, and $matches[1] should be just the first capture group (the stuff between the brackets in this case). Are you wanting to do something like:

return array($matches[0], $matches[1]);

Are you referring to?

$result = emailregex();

echo $result[0];
echo $result[1];

Try this, and follow the instructions in the output carefully.  The wickets<> are being treated as HTML.  View source is your friend.

<?php // RAY_temp_rgb192.php
error_reporting(E_ALL);

// FROM THE POST AT EE
function emailregex($str)
{
    // A REGULAR EXPRESSION TO FIND THE FROM-EMAIL ADDRESS
    $regex
    = '#'         // REGEX DELIMITER
    . '.*?'       // ANYTHING OR NOTHING
    . '\<'        // ESCAPED WICKET
    . '(.*?)'     // GROUP OF CHARACTERS WITH EMAIL ADDRESS
    . '\>'        // ESCAPED WICKET
    . '#'         // REGEX DELIMITER
    ;


    // ISOLATE THE FROM EMAIL ADDRESS
    preg_match($regex, $str, $matches);
    return $matches;
}

// TEST THE FUNCTION
$dat = " Ray <ray.paseur@gmail.com>";
$ret = EmailRegex($dat);

// SHOW THE OUTPUT
echo '<h1>USE THE BROWSER FEATURE "View Source" TO LOOK AT THIS</h1>' . PHP_EOL;
var_dump($ret);

Not sure I understand empty function() either, but thanks for the points.  You might consider something like this...

function emailregex($str=FALSE)
{
    if (!$str) return array();
    /* etc */...
