Is it possible to use MySQL and PHP programming to put squid rules

Yes, for some definition of "put outside":
* One can use external ACL to make match/mismatch decisions (and supply
metadata to Squid from) "outside" of the Squid process. Many Squid
directives are controlled by ACLs, so one can control the corresponding
Squid behavior from the "outside" by using external ACLs and/or
annotations set by external ACLs. You can find examples of external ACL
helpers/programs in src/acl/external/ directory. Your helper program can
be written in most languages, but there are some (possibly stale)
caveats at [1]. An external ACL is a _slow_ ACL; some Squid directives
only support "fast" ACLs[2].
* One can generate squid.conf file (or portions of the configuration
included into that file) from the information in a database (or from any
other source of information), of course. You will need to reconfigure or
restart (depending on what has changed and other factors) the Squid
instance for Squid to notice such configuration changes.

HTH,
Alex.
I heard about it using external acl, but can find any documentation or
good example of it.
I would like to “transfer” parameters as ACLs, HTTP_ACCESS, HTTP_PORT,
and TCP_OUTGOING_ADDRESS from squid.conf to a DB+PHP solution.
