How to remove all numbers from string?

Question

I\'d like to remove all numbers from a string [0-9]. I wrote this code that is working:

$words = preg_replace(\'/0/\', \'\', $words ); // remove numbers
$wor         


        

Answer 1

For Western Arabic numbers (0-9):

$words = preg_replace('/[0-9]+/', '', $words);

For all numerals including Western Arabic (e.g. Indian):

$words = '१३३७';
$words = preg_replace('/\d+/u', '', $words);
var_dump($words); // string(0) ""

• \d+ matches multiple numerals.
• The modifier /u enables unicode string treatment. This modifier is important, otherwise the numerals would not match.
