Never come across anything special like that. Perhaps just a method '_' in AppUI? Look at the code 🙂

Thanks first,
can you explain this a little for me.

function _( $str, $case=0 ) {
$str = trim($str);
if (empty( $str )) {
return '';
}
$x = @$GLOBALS['translate'][$str];
if ($x) {
$str = $x;
} else if (@$this->cfg['locale_warn']) {
if ($this->base_locale != $this->user_locale ||
($this->base_locale == $this->user_locale && !in_array( $str, @$GLOBALS['translate'] )) ) {
$str .= @$this->cfg['locale_alert'];
}
}
switch ($case) {
case UI_CASE_UPPER:
$str = strtoupper( $str );
break;
case UI_CASE_LOWER:
$str = strtolower( $str );
break;
case UI_CASE_UPPERFIRST:
break;
}

Looks like it performs some sort of language translation?

It defines a function named _. You can do that in PHP.

Ah thought he wanted to know what the function actually did 🙂

I've seen code once that used variables like $ and $ and functions called _() and () - someone was asking what they meant.

It's a silly name.
