sendmail and qmail both run on the same server. How can I know the which one is used to send email ?
I have a PHP application that sends email via the mail() function. The SMTP server it uses has both process running.
It is a server used for live applications, so I can't stop one process to do some tests.

I'd make sure that the machine really is as you describe. It's possible to get confused about these things, especially as most Unix/Linux MTSes have asendmailprogram image file that is nothing whatsoever to do with the Sendmail software package. There's almost never a need to set up a system in this way with two different MTS softwares running in parallel. (Multiple instances of one package is as exotic a configuration as things normally get.)

You will have to look in your php.ini file, under [mail function]. Here, the path to the mail sending binary is specified. Whatever is specified here, the mail() function in PHP will use.
sendmail_path = /usr/sbin/sendmail -t -i
The above one should be the default. So, if you haven't changed anything, PHP will use sendmail.
As @JdeBP mentions, you can also take a quick look at the headers of the mails received. If you look under the various Received sections, you will find some identification of the server software being used.

+1. The suggestion in the PHP manual is to pointsendmail_pathdirectly atqmail_inject, which will be directly indicative with no further research. But in the general case finding out whose binarysendmail_pathis pointing to is the right answer for PHP on Unix/Linux.

While you're at it, you could mention in your answer that theReceived:header fields in the received messages will yield very strong clues as to which software, Sendmail or qmail, processed the mail. Sendmail and qmail write trace information in different forms.
