What does the French shutdown entail?
The measure applies to restaurants, cafes, cinemas and nightclubs as well as non-essential businesses.
It would not, Philippe said, affect essential businesses which he listed as food shops, chemists, banks, tobacco shops and petrol stations.
Philippe also asked people to reduce their travel, especially between towns.
"The best way to slow down the epidemic", he said, was "social distancing".
"I say this gravely - we must all together show greater discipline in the application of these measures," Philippe added.
However local elections due on Sunday would also still go ahead, he said. Religious buildings would remain open but gatherings and ceremonies should be postponed.
France reported a sharp rise in cases on Saturday, from 3,661 to 4,499. It recorded 12 more deaths, bringing the toll to 79.

What is happening in Spain?
After a lengthy meeting of the country's government cabinet, Spanish Prime minister Pedro Sánchez said a partial lockdown would be in place across the country, with the armed forces on standby to assist with relief efforts.
All shops will be forced to close, except for those selling food and other basic necessities.
There will also be a reduction in medium-distance rail traffic to stem the spread of people around the country, and economic measures to support businesses and workers.
Sánchez said the state of emergency could be extended with congressional approval.
Authorities recorded 1,800 more cases since Friday evening - many in the capital Madrid.
This will be the second state of emergency in the country since the transition to democracy began in 1975, the first being a 2010 air traffic controllers' strike.
