how do you read the last line in php and parse out certain columns

Question

I am very new to php. I\'d really appreciate all the help here.

I am using sftp to login to a server and get a file. I am only interested in the last line in that file.

Answer 1

Why use php?

With input file:

7   1   0   59422170     306669 20188 20386     0     0 39787  59981  2014  67796 48953  2  7 90  1  1.81  11.3 12:19:50

and command line:

tail -n1 myfile | sed 's/\s\s*/ /g' | cut -d' ' -f15,16,19,20,21

result is:

2 7 1.81 11.3 12:19:50
