xgettext PHP parsing bug with associative arrays

[Robert Vock]

Hello there,

we are just switching to gettext in our PHP project and I noticed a
bug in xgettext, when extracting from PHP files with associative
arrays:

<?php
$array = array( 'key' => 'value' );
echo gettext( $array['key'] );
?>

xgettext extracts the msgid "key" from this code example.
The resulting po file will contain:
msgid "key"
msgstr ""

I think, to fix this bug, the x-php.c must also parse the square
brackets and ignore the inner contents. (Just as it does with the
parentheses)

Workarounds within PHP exist:

1. workaround:
use a dummy function to prevent the parsing

<?php
function fixXgettext( $str ) { return $str; }

$array = array( 'key' => 'value' );
echo gettext( fixXgettext( $array['key'] ) );
?>


2. workaround:
use a temporary variable

<?php
$array = array( 'key' => 'value' );
$str = $array['key'];
echo gettext( $str );
?>


Greetings,

PS:
Is there a bugtracker for GNU projects? I did not find one and I could
not find anyone who had the same problem...
