Auto-create Android logs?

Question

PHP

The question arose - is it possible to create log files on android when certain triggers are triggered? For example, if a new application is installed on the device, you need to create a "newapp.txt" file in a specific directory. The contents of the file should contain the name of the installed application and the date/time of installation. Or if a certain date/time came (say, 04/11/2020 at 13:00), a "datetime.txt" file with empty content was automatically created.

For example, I installed google chrome on my device, and in the required directory (which I predetermined) a "newapp.txt" file appeared with the following content:
04/11/2020 11:00 AM New app installed - Google Chrome
After that, on 04/11/2020 at 13:00, the second trigger worked (the right time came) and an empty file "datetime.txt" appeared in the right directory (which I had previously determined) Tell me

which way to look, and are there already existing applications that solve the task at hand?
Thank you.

Answer 1

Where did you lose the array key? You declare that you write in 48 fields, in fact you write in 49, just the same element without a key is superfluous. Duty comment about SQL-Injection

'$newnames[13]',
'$newnames[]',
'$newnames[14]',

Terrified, remove this hell and make a separate table for pictures.
Write queries using prepared expressions.
Do not play up and do not make excuses, but do both.
