Remove everything after the first space

I'm working in PHP and have a variable set to "firstname lastname". I wish to set a new variable to just the first name, by stripping out the space and anything after it using a regular expression. Can anyone help with the syntax to do so?

list($firstname, $everythingelse) = explode(' ', $string, 2);

Hi there. Try this:

$name = "John Smith";

if (preg_match('/[\\w]*/', $name, $regs)) {
      $result = $regs[0];
} else {
      $result = "";
If you insist on regular expression use:

$firstname = preg_replace('/^([^ ]+).*/', '\1', $name);
