The goal of this PHP test is to take you to space with the picture of the day by the Nasa. We want to display a page on our website that will show us the current picture of the day (and its description). To achieve that, NASA gives us an API to fetch the data from their server. Unfortunately, This API has a limit on the number of calls we can make. So we will store the images on our side.
Here is an example of the response by the API :

"explanation": "Get out your red/blue glasses and float next to asteroid 433 Eros. Orbiting the Sun once every 1.8 years, the near-Earth asteroid is named for the Greek god of love. Still, its shape more closely resembles a lumpy potato than a heart. Eros is a diminutive 40 x 14 x 14 kilometer world of undulating horizons, craters, boulders and valleys. Its unsettling scale and unromantic shape are emphasized in this mosaic of images from the NEAR Shoemaker spacecraft processed to yield a stereo anaglyphic view. Along with dramatic chiaroscuro, NEAR Shoemaker's 3-D imaging provided important measurements of the asteroid's landforms and structures, and clues to the origin of this city-sized chunk of Solar System. The smallest features visible here are about 30 meters across. Beginning on February 14, 2000, historic NEAR Shoemaker spent a year in orbit around Eros, the first spacecraft to orbit an asteroid. Twenty years ago, on February 12 2001, it landed on Eros, the first ever landing on an asteroid's surface. NEAR Shoemaker's final transmission from the surface of Eros was on February 28, 2001.",

}For now, we only need these informations that will be displayed on our website, and thus will be saved on our database :
- title ;
- explanation ;
- date ;
- image.
The application will only be accessible by logged in users. To achieve that, the login process will use Google as a login provider.
Here are the steps you may want to follow to achieve this challenge :
- Step 1: make a CLI command that will be executed each day to fetch the picture of the day ;
- Step 2: make a page to display the picture of the day. If there is no picture (say the picture of the day is a video) we will display the picture of the previous day ;
- Step 3: protect our app, so the picture will only be visible by a logged in user. The user will be able to connect with a Google account using Google as login provider ;
- Step 4: make a small documentation explaining what you did, the technologies you used etc.
To fetch pictures from the NASA API, you need an API key. It will be sent to you by email.
When you finish this challenge, send a link to your repository by email.
The only constraint is to use PHP (use the version you want) and this Symfony project. You will then use any library you want, any database you want.
And most of all, have fun!
Step 1: make a CLI command that will be executed each day to fetch the picture of the day ;
The command checks first if the image of the day is already saved. If it is not, it will call the api and save the image in the database (only if the media type is image). Make sure to set the API KEY in the .env file
Step 2: make a page to display the picture of the day. If there is no picture (say the picture of the day is a video) we will display the picture of the previous day ;
For this purpose, this page display always the last image saved in the database. The check of the media type is done beforehand in the CLI.
Step 3: protect our app, so the picture will only be visible by a logged in user. The user will be able to connect with a Google account using Google as login provider ;
The bundle knpuniversity/oauth2-client-bundle is used for this purpose, make sure to set google client ID and secret in the .env file
Step 4: make a small documentation explaining what you did, the technologies you used etc. Hope this small doc you're reading is enough :)
