i need to use $matches[0] and $matches[1]

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]);

$matches[0] is the name 'ray'
and
$matches[1] is the email

if I do

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

I dont know how to call and echo
array($matches[0], $matches[1])

kaufmed

Are you referring to?

$result = emailregex();

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

Ray's code take the parameter. So it works for me.

I cant understand how to do an empty function() with this

thanks

Ray Paseur

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 */...
