Extracting a price using preg_match in PHP

Question

I have a string that, from a file_get_contents() call, contains something like:

    <span class="cb_price_countdown cb_lot_price_1439066">$40.65</span>

And I would like the extract the price 40.65. I am not familiar with regex or preg_match so I'm having a hard time. So far I have tried:

    $pattern = "/\\\$?((\d{1,3}(,\d{3})*)|(\d+))(\.\d{2})?$/";
    preg_match ($pattern, $subject, $matches);
    print_r ($matches);

Which is not returning anything useful, and I've tried:

    $pattern = "/[\d+|\d+,\d+]\.\d{0,2}/";

but it's the same story. Can somebody please tell me the correct preg_match pattern that I'm looking for?

Thank you,
Justin

don't use regular expressions for this. Don't steal content from other sites. — , Feb 17 '13 at 19:34

use this:

preg_match ( '/\$(\d+\.\d+)/', $subject, $matches );

$result = array();
$str = '<span class="cb_price_countdown cb_lot_price_1439066">$40.65</span>';
preg_match('/<span[^>]*>\$(.*)<\/span>/', $str, $result);
var_dump($result);

yields:

array(2) { [0]=> string(61) "$40.65<" [1]=> string(5) "40.65" }
