preg_match frustration

[GazK]

Can someone help a regex noob?

my code:

$text = "clapham junction 1989";
$regexp = "[0-9][0-9]{3}";
$dummy = preg_match($reg exp, $text, $matches);
echo $matches[0];

produces the error:

Warning: preg_match() [function.preg-match]: Unknown modifier '[' in
blah blah blah

Have I got the regex wrong? I'm trying to return any 4 digit number in
$text.

thanks in advance

You have to use delimiters around your regex, e.g.

$regexp = '/[0-9][0-9]{3}/';

See the manual for syntax details.

Shorter:

/\d{4}/
