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

Use Predefined Character Ranges

echo $words= preg_replace('/[[:digit:]]/','', $words);

Answer 2

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.

Answer 3

Regex

   $words = preg_replace('#[0-9 ]*#', '', $words);

Answer 4

Use some regex like [0-9] or \d:

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

You might want to read the preg_replace() documentation as this is directly shown there.

Answer 5

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.
