How to remove numbers from a string with RegEx

Question

I have a string like this:

" 23 PM"

I would like to remove 23 so I'm left with PM or (with space truncated) just PM.

Any suggestions?

Needs to be in PHP

Answer 1

echo trim(str_replace(range(0,9),'',' 23 PM'));

Answer 2

Can do with ltrim

ltrim(' 23 PM', ' 0123456789');

This would remove any number and spaces from the left side of the string. If you need it for both sides, you can use trim. If you need it for just the right side, you can use rtrim.
