Doesn't it print to stdout? Reading your message, it appears that one
triple (in N-Triples format) was extracted and print to stdout.

extract_test.php downloads the page specified in extract.php from
Wikipedia (which explains the delay). In this case, it is the article
about "London". It then runs the extractor specified in extract_test.php
on this article (by default "SampleExtractor"). The result is printed to
stdout.

As mentioned previously, extract_full.php should be used for producing a
complete DBpedia release (but you need to use import.php to download the
corresponding Wikipedia dumps before and import them in MySQL databases).

Kind regards,

Jens
