Running a Unix Command-Line App via PHP?

I'm developing a web site in PHP for an Apache server.

I have a particular stand-alone application that takes a text file as
input, and produces a text-file as output. It's usually run from the
Unix command line. I'd like my PHP code to provide the input text file,
run the stand-alone application, and then read the output text file and
reformat it for display on the site.

Is there a way for my PHP app, to cause this Unix command-line
application to run?

Thanks in advance to all for any info.

see the system() function in the manual. If your application can write to
STDOUT instead of writing to an output file, you can use the backtick
operator (see execution operators in chapter 15).

Hi,

I suppose you work with a LAMP configuration so, to execute on your O/
S an application, you must use system() or exec() functions.
Take care about input! If you use directly data from user input, think
about escaping them.
