In Europe, McDonald's biggest market, sales fell 2.1 percent as Germany and France dragged down results. The company said it remains focused on enhanced value and keeping stores open longer in the region.
In the U.S., McDonald's said the figure edged up 0.9 percent. The addition of the Grilled Onion Cheddar burger to the Dollar Menu boosted results.
For February, McDonald's noted sales will be hurt by about 3 percentage points since the previous year's results included an extra day because of the leap year.
The monthly sales figures are a snapshot of money spent on food at both company-owned and franchised restaurants and do not reflect corporate revenue.
McDonald's shares rose 24 cents to close at $94.87 Friday.
