&lt;?=__('Add')?&gt;

<?=__('Add')?>

epimeth

been a while....

what does __() do? I assume it returns whatever string is in the parens, but I can't be sure until someone here tells me it is 🙂

so <?=__('Add')?> returns the string Add?

I couldn't find this in the manual.....

Never heard of it...

What's wrong with <?php echo "Text"; ?> ???

mmm... just noticed another file....

$__ = Array(.....)

so now I'm not confused in one thing, but yes in another!

can the $ be dropped when using <?= to display a string???

the code uses <?=__('Blabla')?>....

I think that the __('text') is a function call, which may work something like this:

<html>
<body>
<pre>

<?php


$__ = array('foo','bar','three'=>'quux');
function __($key) {
    global $__;
    return $__[$key];
}


print_r($__);


?>
<hr />
<?='one ','two ',__('three'),' ',$__['three']?>
</pre>
</body>
</html>

The <?= ... ?> construct is just a shortcut for the echo statement. Any comma separated list of expressions is allowed there. Look through your source code for a function named __

ok... just so none of you have an aneurism wondering about what the hell this __ thing is... let me explain whats up and why I'm still confused.

I'm using some closed source php code, so I don't know all the constants and functions, nor can I find out. All I understand is that I found a file in ..../languages/template which contains an array:

$__ = Array(
  'Add' => 'Add',
  'Delete' => 'Delete',
  ....
  ....
  ....
)

and thats it. now back in the file I was editing there are labels that I assume are meant to change if the language changes, so having an array like that seems like a logical thing to do. However, when retrieving the values of words in the array, the $ is omitted, yet the value is still displayed:

<?=__('Add')?>

how is this possible???

I do know that _() is an alias of gettext(), but that's only 1 underscore.

Maybe the original coder is trying to emulate $_ as in Perl?

The double underscores confuse me though, it seems that whoever was coding was trying to be esoteric about it.

You can find out all the constants and functions. See get_defined_functions() and get_defined_constants()

Closed source - that's the key:

<?php
function __($foo)
{	echo "This function has a deliberately hard-to-pronounce name. And no, it's not $foo.";
}

__('Barry White');

?>

I recon somewhere in index.php is an include that pulls in whatever is in the language folder (thats where I found the $ array) and makes a bunch of constants based on the $ and makes them just __... whatever... as long as it works :-)
