Underscore in Echo?

[Wynder]

Seen this used:

echo _("This is a test.");

What's this do? 🙂

[kazer]

_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

[Wynder]

Well, that makes sense...

what you supplied will simply cause a fatal error, cuz you are trying to call an undefined function

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

[Wynder]

Works fine for me... apache 2.0.40, PHP 4.2.3.

[stolzyboy]

hmmm...i would think that it shouldn't, to you have all error reporting turned off

[Wynder]

error_reporting = E_ALL & ~E_NOTICE

From /etc/php.ini.

[stolzyboy]

tis very strange nonetheless

[Wynder]

Indeed... thanks for the help! Glad I got the answer I was looking for.

Resolved. 🙂
