convert to int php

Question

I use php programming for get information from txt file like this:

< n >1< /n >< fr >2,3,4,5,6,7,8< /fr >< fo >9,10,11,12< /fo >

between tag < n > I can get number 1 by using preg_match

$users = preg_match_all("/<".$tag.">[^<]*(.*?)<\/$tag>/si", $content, $matches,PREG_PATTERN_ORDER);

so the data is stored in $user[0] right?

when I convert $user[0] to integer, it turns to 0 !!!

Could you please help me fix this

I want to convert this and insert into database

You are using a regular expression to extract data from XML. Don't do this. Use an XML parser to parse your XML. — user229044, Apr 02 '13 at 15:32

For beginners I'd recommend [SimpleXML](http://php.net/simplexml). See the [Examples](http://www.php.net/manual/en/simplexml.examples.php) section. — Álvaro González, Apr 02 '13 at 15:35

The data is stored in the multi-dimensional array $matches. In $users will be "the number of full pattern matches (which might be zero), or FALSE if an error occurred." see documentation http://www.php.net/manual/en/function.preg-match-all.php
