Need quick help with regexp, to search a string for
blah blah blah price 4.000 blah blah
and assign 4.000 or whatever number comes after price to a variable.

preg_match("/price (.*?) /i", $string, $match);Lawrence Cherone– Lawrence Cherone2011-07-14 03:09:26 +00:00Commented Jul 14, 2011 at 3:09

As can be seen from the posts below, even after the regular expression match, it behooves one to try converting the extracted data into a number and react to any failures accordingly.user166390– user1663902011-07-14 03:28:30 +00:00Commented Jul 14, 2011 at 3:28

@pst: are you sure? ;-) What about
$matches[1]?zerkms
@pst: yep. That's because I've solved the task of parsing the data, not its validation ;-)
$num = preg_replace('/price ([\d,\.]+)/', '\1', $string);
or
preg_match('/price ([\d,\.]+)/', $string, $matches);
$num = $matches[1];

It will not match
4.000 ;-)
A-OK
will this work if the number contains a decimal point (dot) and a thousand separator (comma)?

@pst - Yep. You don't want to commit the crime of unnecessary escaping :)

@pst - Also, you changed your comment about escaping
