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

Try with regex \d:

$words = preg_replace('/\d/', '', $words );

\d is an equivalent for [0-9] which is an equivalent for numbers range from 0 to 9.
