get the dataset by

wget -c http://wikipedia.c3sl.ufpr.br/enwiki/20150901/enwiki-20150901-pages-articles.xml.bz2

changed the correponding configuration

$dsname = 'mongodb://wiki:wiki@localhost:27017/wikipedia';
$file = '../data/enwiki-20150901-pages-articles.xml.bz2';
$logpath = './';

and run from the command line

php wikipedia.org-xmldump-mongodb.php

get error:

You have to escape the > character. In the script file, on line 72 replace this line:

$chunk = str_replace( [ 'letter">', '</namespace>' ], [ 'letter" name="', '" />' ], $chunk );

With:

$chunk = str_replace( [ 'letter"\>', '</namespace\>' ], [ 'letter" name="', '" /\>' ], $chunk );

That made it work for me!
