OS Monterey Apache and Homebrew PHP 8.1

I am trying to use PHP 8.1 (from a Homebrew installation) on Mac OS Montere=
y alongside the built-in version of Apache 2.0

I understand the PHP module has to be codesigned and I=E2=80=99ve done that=
. Unless I=E2=80=99ve misunderstood, the name of the certificate needs to b=
e added at the end of the LoadModule command in httpd.conf.  Hence, I have =
entered it this way with James being the name of the certificate:

LoadModule libphp.so /usr/local/opt/[email protected]/lib/httpd/modules/libphp.so Jam=
es=20


    <FilesMatch \.php$>
        SetHandler application/x-httpd-php
    </FilesMatch>

When I run apacheconfig, I get this error:


Mon Mar 28 12:57:45.226774 2022] [so:notice] [pid 52143] AH06662: Allowing =
module loading process to continue for module at /usr/local/opt/[email protected]/lib=
/httpd/modules/libphp.so because module signature matches authority "James"=
 specified in LoadModule directive
httpd: Syntax error on line 191 of /private/etc/apache2/httpd.conf: Can't l=
ocate API module structure `libphp.so' in file /usr/local/opt/[email protected]/lib/h=
ttpd/modules/libphp.so: dlsym(0x20392b0a0, libphp.so): symbol not found

The "dlysym" error is associate with my putting the name of the code signin=
g certificate named James at the end of the module.=20

What am I doing wrong here?  I have a feeling it=E2=80=99s something fairly=
 simple.

Thank you
