How to get filenames from string in php?

Question

PHP

Good day.
Through the program, I upload to the server a text file with a list of processes on the computer.
File content example:
smss.exe 280 Services 0 23ya028 Unknown
csrss.exe 400 Services 0 23ya028 Unknown
wininit.exe 476 Services 0 23ya028 Unknown
services.exe 580 Services 0 23ya028 Unknown
lsass.exe 588 Unknown Services 0
23ya028 .exe 648 Services 0 23J028 ЉЃ Unknown
After processing with a php file, it should look like this:
smss.exe
csrss.exe
wininit.exe
services.exe
lsass.exe
svchost.exe
Can you tell me how to implement this?
