Simple PHP script

I need a php script that will output a table from reading all the files in a specified directory and create a table of the filename, the contents (which will be an integer between 0 and 100) and the mod time on the file like so filename <td> integer [ contents of the file ] <td> mod time < When the integer is 0 the color of the bgcolor should be light red when the integer is <= 2 the color of the bgcolor should be a light yellow when the integer is > 2 the color of the bgcolor should be a light green when any of the rows are clicked on in this table, the script needs to call itself again and rewrite the file specified by the row that was clicked on, decrementing the integer that was in the file by 1 and redisplaying the table. When a file has the contents of "0" the script should not perform any actions This should be a single standalone script creating a table. It will be called from within an iframe of another page which already has its own css. The following variables should be declared at the top of the php script path to the directory font in use for the table bgcolor for integer = 0 bgcolor for integer <= 2 bgcolor for integer > 2 Example output would look like this test1 100 2019-02-01 10:19:02 test2 10 2019-03-01 10:29:12 test3 13 2019-04-01 11:39:32 test4 19 2019-05-01 12:49:22 If the user clicked on the row representing test1 the contents of test1 would be altered to "99" and the table would be redisplayed as below test1 99 2019-06-01 01:10:02 test2 10 2019-03-01 10:29:12 test3 13 2019-04-01 11:39:32 test4 19 2019-05-01 12:49:22
