Problema con array

[abimaelrc]

Trata algo así

Código PHP:

<?php
$archivo = str_replace( basename($_SERVER['PHP_SELF']) , '' , $_SERVER['SCRIPT_FILENAME']) . '/lang/prueba.po';
$leer = file($archivo, FILE_IGNORE_NEW_LINES);
$arr = array();
$bool = true;
$n = 0;
foreach($leer as $l){
    $e = explode(' ', $l);
    if(empty($e[0]) || $e[0] == '#'){ $bool = true; continue; }
    $arr[$n][$e[0]] = $l;
    if($bool){ $bool = false; $n++; }
}
foreach($arr as $a){
    echo (!empty($a['msgid']) ? $a['msgid'] . '<br />' : '')
        . (!empty($a['msgstr']) ? $a['msgstr'] . '<br />' : '')
        . (!empty($a['msgstr[0]']) ? $a['msgstr[0]'] . '<br />' : '')
        . (!empty($a['msgid_plural']) ? $a['msgid_plural'] . '<br />' : '')
        . (!empty($a['msgstr[1]']) ? $a['msgstr[1]'] . '<br />' : '') . '<br />';
}
