Question

I seem to be having a problem with a preg_match code, I am trying to get the decimal number from a string which should be something like ‘3.25’ but instead I get ‘1’

preg_match('/[0-9]+(?:\.[0-9]*)?/', '£3.25', $matches);
echo 'match: '.$matches[0];

prints “1”

Answer 1

preg_match('#\d+(?:\.\d{1,2})?#', '£2.35', $match);
var_dump($match);

gives

array(1) {
  [0]=>
  string(4) "2.35"
}

even on PHP 5.2 : http://codepad.viper-7.com/9nFhET
