Quick PHP question :)

How do I remove spaces from something a user typed in?If they type "hello world" into the text box and hit submit, how would i make it submit as "helloworld"??php.net doesnt like me and I can't really find anything on that site ever. I've used this before but can't remember what it is.

<?php$str = 'hello world';$str = preg_replace(' ', '', $str);// This will be 'helloworld' nowecho $str;?>

just replace 'space' with nothing, to remove spaces...

I got this error when I used that:Warning: preg_replace() [function.preg-replace]: Empty regular expression in C:\Sites\page.php on line 13

To turn multiple spaces into one space, you'll need a regular expression like this:

$RegExp = '%[\s]{2,}%';$Text = preg_replace($RegExp, ' ', $Unfiltered);

Hope it helps EDIT: Oh, i missunderstood what you wanted to do. Instead of using a regular expression, this should work just as well:

$Text = str_replace(' ', '', $Text)

That will give you what you need, and it's plenty faster than regular expressions too.

Thanks! That works.

use this regexp to filter spaces

$newString = eregi(" *", $string);

It should remove all spaces from the string

How about trim($str) ? Wouldnt that take off spaces..

trim only removes spaces from the beginning and end of the string, not in the middle
