At the command-line :

ps -ef | grep httpd | grep -v grep | wc -l
or, better :
ps -ef | grep "[h]ttpd" | wc -l

(replace by "apache" or "apache2" if needed.)


At the program level :
find the function that lets you execute a system command and capture 
it's output, then use the above as command.
e.g. in perl you can just do :
my $var = `ps -ef | grep "[h]ttpd" | wc -l`;

There are a number of more sophisticated alternatives in each 
programming language, but that's a simple way.
