Removing all unwanter charachers but A-Z and a-z

[pioneerx01]

In my form people are being asked for name which gets entered into database. How do I take my "$_POST[name]" and remove all characters but A-Z and a-z. I do not want ~`!@#$%^&*()_-+={[}]|\"':;?/>.<, there at all or numbers for that matter.

 

I have been paying with stripslashes and strip_tags but they don't fully cut it

 

Thanks

One of the things a regular expression is good at: saying "everything except".

preg_replace('/[^a-zA-Z]/', "", $text)

i agree i love the 'except rule: ^', or you could do it this way with the 'i' for case insensitive, whichever 

 

$string = 'me.]';

$nw = preg_replace("/[^a-z]/i",'',$string);
echo $nw;

Fantastic. Works like a charm. I have added a space because when someone enters First Last Name I get FirstLastName

 

preg_replace('/[^a-zA-Z ]/', "", $fn1)

 

Thank you all. This site rocks!
