preg_replace

ok heres the sample off the php site.

php Code:

Original - php Code
$string = "April 15, 2003"; $pattern = "/(w+) (d+), (d+)/i"; $replacement = "${1}1,$3"; echo preg_replace($pattern, $replacement, $string);

 
$string = "April 15, 2003";
$pattern = "/(w+) (d+), (d+)/i";
$replacement = "${1}1,$3";
echo preg_replace($pattern, $replacement, $string);

can some one please explain to me how the "${1}1,$3"; and the "/(w+) (d+), (d+)/i"; work and perhaps suggest a link where i can learn about these, because to me that just looks like a mess. I have no idea how that could do anything....

RE: preg_replace

Hi!
Look at the PHP-manual, section:
