Seen this used:
echo _("This is a test.");
What's this do? 
Underscore in Echo?
_echo is used in some programming languages to echo the contents of a file. (I'm pretty sure XML uses this).
I don't believe it does anything in PHP (except spit out an error probably 
).

Not _echo
echo _("This one");
=)
It's actually used quite extensively in the Horde project, but I don't know what it does.
what you gave an example to is nothing more than a call to a function called "_" underscore, take this for example
<?
function _()
{
echo "This is a test.";
}
echo _();
?> that will echo // This is a test.
what you supplied will simply cause a fatal error, cuz you are trying to call an undefined function
Well, that makes sense...

Actually, making a little script:
<?php
echo _("test");
?>Works fine. Odd.
not in a file alone with nothing else in it, it doesn't work
Works fine for me... apache 2.0.40, PHP 4.2.3.
hmmm...i would think that it shouldn't, to you have all error reporting turned off
error_reporting = E_ALL & ~E_NOTICE
From /etc/php.ini.
tis very strange nonetheless
Indeed... thanks for the help! Glad I got the answer I was looking for.
Resolved.
