-c, --count
Suppress normal output; instead print a count of matching
processes. When count does not match any‐
thing, e.g. returns zero, the command will return non-zero value.
Looks like you would want to use the --count flag instead of piping to wc:

Hey peeps.
From a fed/centos cmdline...
pgrep -f "foo" | wc -l
will return 0 -- if "foo" doesn't exist in the procTBL, and something
else if "foo" is running.
The curiousity... When I have a simple php
$t isn't 0!! -- it's actually 1, or something else if foo is running..
Any ideas why??
