[php] preg_replace

[Miiisa]

ja regularni vyrazy chapu, ale nak mi nejde do hlavy tohle:

<?php
$string = "April 15, 2003";
$pattern = "/&#40;\w+&#41; &#40;\d+&#41;, &#40;\d+&#41;/i";
$replacement = "\$&#123;1&#125;1,\$3";
echo preg_replace&#40;$pattern, $replacement, $string&#41;;
?>

teda spis tohle:

$pattern = "/(\w+) (\d+), (\d+)/i";
$replacement = "\${1}1,\$3";
