Good question.

The @ symbol checks for errors (will return true if it finds errors, otherwise false). For example:

PHP Code:


mysql_connect('localhost', 'root', '');
if(@mysql_connect('localhost', 'root', '')){
  die("Error!");
}

This will check to see if there are any errors in connecting to the database, if there are die Error!.

RMS - Root Mean Square.

The @ sign means that no error messages will be printed if the getMemberThumbnail does not succeed.

RSS - Rich Site Summary RSS Definition

Not sure about RMS though.

hum? :: thinking::

so does anyone here know about "RMS"?, i work with dolphin software from boonex.com , ti uses rms on it.

what is it and what is it used for?

I think it may be something dolphin software made up. When I search RMS 3.5.1 on google I get this.

Dolphin 6.1.1 & RMS 3.5.1 :: hd4real's blog
So, I think I finally have RMS 3.5.1 working on my server. My only problem now is that my Ray widgets do not load. This happens with Adfree & Free 6.1.1 ...

so , do you think that RMS is dolphin's own modules?

if it so, just boonex.com that know what is it and what is it used for on my dolphin.

**Nile** · 02-03-2009, 04:16 AM

Well, not just boonex.com. But I do think it is just dolphin's.

Although - I don't really know.

Nile, not exactly. The @ symbol causes errors an expression may cause to be ignored or supressed. A common use is to ignore errors the mysql_connect() function may cause because printing these errors on the screen could compromise your database security.

Remember that when you are developing a site you want to see ALL errors your code produces, but when the site is live you don't want to display errors to the users. Especially errors that could compromise your sites security. You have to figure out an elegant way of handling errors on your live site. For example, depending on what kind of error occurs, you could just ignore it, display a "Sorry" message to the user, and / or have error information emailed to you or logged somewhere.
