Hello
I hope you’re fine
I store the received data in a file data base as follows:
[“0.4″,”0.4″,”0.5″,”0.43”,1522731408]
[“0.3″,”0.3″,”0.3″,”0.39”,1522731468]
[“0.3″,”0.3″,”0.3″,”0.33”,1522731529]
[“0.2″,”0.2″,”0.2″,”0.25”,1522731590]
[“0.1″,”0.1″,”0.1″,”0.2”,1522731650]
[“0.1″,”0.1″,”0.0″,”0.15”,1522731711]
[“0.1″,”0.0″,”0.0″,”0.12”,1522731771]
[“0.0″,”0.0″,”0.0″,”0.09”,1522731832]
[“0.2″,”0.0″,”0.0″,”0.08”,1522731892]
[“0.1″,”0.0″,”0.0″,”0.07”,1522731953]
[“0.0″,”0.0″,”0.0″,”0.06”,1522732013]
[“0.1″,”0.0″,”0.1″,”0.06”,1522732074]
[“0.1″,”0.0″,”0.0″,”0.06”,1522732135]
[“0.0″,”0.1″,”0.2″,”0.05”,1522732195]
[“0.0″,”0.0″,”0.0″,”0.05”,1522732256]
[“0.1″,”0.0″,”0.0″,”0.06”,1522732316]
[“0.1″,”0.0″,”0.0″,”0.05”,1522732377]
[“0.1″,”0.0″,”0.1″,”0.04”,1522732437]
[“0.0″,”0.0″,”0.1″,”0.03”,1522732498]
[“0.1″,”0.0″,”0.1″,”0.03”,1522732559]
[“0.1″,”0.0″,”0.0″,”0.04”,1522732619]

The first four are the data, and the last number is the timestamps

Now I do not need past information
And I want to erase the previous day’s information
How should I do this?
Can you give us an exact example?
thank you
