I’m doing a string concatenation:
$url = "http://www.majesticseo.com/reports/site-explorer/summary/"
+ $page['page_url'] + "&IndexDataSource=F"
;
and this is what I get when I print it:
0
where does the 0 come from?
It comes from the fact that you’re performing an arithmetic operation on non-numeric data. Use the concatenation operator (
.) instead.
