Question

I am Parsing a web page for getting the web page prize. the prize include a Rupee symbol (₹).

So i used preg_replace to extract digits.

For example:

$str='₹ 1,195 ';
echo preg_replace("/[^0-9]/", '', $str);

Output is :

2091195

I tried same code to execute on http://writecodeonline.com/php/.

There i m getting correct output 1195.

I’m not getting what is the problem.

Thanks in Advance

If the unicode string is UTF-8, you can use the u (PCRE_UTF8) modifier^Docs to tell preg_replace that it should use UTF-8 mode. If not, re-encode it to UTF-8 first and then use the modifier.

Example (Demo):

$subject = '₹ 1,195 ';
$pattern = "/[^0-9]/u";
$result  = preg_replace($pattern, '', $subject);

echo $result;
