PHP ereg_replace允许空格

Question

using preg_replace I want to allow only alphanumeric and spaces, but ereg_replace("[^A-Za-z0-9\\w\\] deletes all spaces.

What could I do in order to fix it?

Thanks in advance

Answer 1

you forgot a space

[^A-Za-z0-9\w\ ]
______________^

eg:

$returnValue = preg_replace('@[^A-Za-z0-9\w\ ]@', '', 'I forgot a %space!!!');
// I forgot a space
