split Deprecated

 11:03 pm on May 29, 2012 (gmt 0)

I was given code that is for password protecting a site. When I try to change the password the site tells me the function split is deprecated. So I looked it up and was told to use preg_split instead.

When I try to use that I get an error message:

Warning: preg_split() [function.preg-split]: Empty regular expression in /home/mmoprotools/www/secure/globalFns.php on line 5

Warning: Cannot modify header information - headers already sent by (output started at /home/mmoprotools/www/secure/globalFns.php:5) in /home/mmoprotools/www/secure/admin/resetPwd.php on line 33

The Code for the first error is :
require_once(dirname(__FILE__) . "/menus.php");

function getFirstName($fullName) {
$parts = split(" ", $fullName);
return $parts[0];

Any suggestions would be greatly appreciated! Thanks!

I no longer need an answer to this. I'm using something else now.

The sample code you supplied didn't contain

I suspect the issue was that you simply changed
split to preg_split without also changing the first argument. The relevant line should be:

$parts = preg_split("/ /", $fullName);

Although using
explode [us3.php.net] may be better in this case.

Agreed, any single character is not really a pattern, any of the 'reg functions are meant to match on patterns. :-)

I know this might seem obvious, but it seems to be frequently misunderstood.

When you get a PHP warning that says "____ is deprecated. Use ____ instead", it doesn't mean that you should just change the name of the function.

It means that you should go to the PHP manual ( [php.net...] ), look up the function you were using, look up the new function, and change your code so it uses the new function properly, using the rules and requirements for its use.

The two functions are often very similar, but they won't be exactly the same.
