DEVELOPMENT server won't stop caching (Vagrant – Apache 2.4 – Centos 7.6 – php 5.6.x ) on MacOSX

I CANNOT DISABLE caching of the PHP files, (haven’t tried html or JS files yet). I just migrated a really old server to the above specs, (except it has RHEL7.6).

I have been using vagrant as a dev server environment for 6 years. I just built a replica for development for the newly migrated server with CentOS 7.6, Apache, and PHP 5.6.40.

I cannot seem to edit and then test those changes at all. I have tried DOZENS of suggestions found online, and at the moment the only way to see any changes I make, is to destroy the box and vagrant up a new box. NOT A SOLUTION.

I’ve tried.
Inline PHP header statements inside the actual file 

<?php header('Expires: '.gmdate('D, d M Y H:i:s GMT', time() + 3600)); ?>

-> FAIL

Adding .htaccess file to the directory I’m working in

 #Initialize mod_rewrite
RewriteEngine On
<FilesMatch ".(php|html|htm|js|css)$">
  FileETag None
  <IfModule mod_headers.c>
    Header unset ETag
    Header set Cache-Control "max-age=0, no-cache, no-store, must-revalidate"
    Header set Pragma "no-cache"
    Header set Expires "Wed, 12 Jan 1980 05:00:00 GMT"
  </IfModule>
</FilesMatch>

-> FAIL

Add to httpd.conf

<IfModule mod_headers.c>
    <filesmatch ".(html)$">
        Header set Cache-Control "no-cache"
    </filesmatch>
</IfModule>

-> FAIL

I created a php file with this to include for developing a file… cacheOff.php:

header("Content-Type: application/json");
header("Expires: 0");
header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
header("Cache-Control: no-store, no-cache, must-revalidate");
header("Cache-Control: post-check=0, pre-check=0", false);
header("Pragma: no-cache");

Then tried this in the file
-> FAIL

I tried commenting out any cache.conf files in the httpd folder conf.modules.d
00-base.conf

LoadModule autoindex_module modules/mod_autoindex.so
#LoadModule cache_module modules/mod_cache.so
#LoadModule cache_disk_module modules/mod_cache_disk.so
LoadModule data_module modules/mod_data.so

-> FAIL

I found php.ini suggestions like opcache, but it isn’t in this version.

Here is my httpd.conf and php.ini files
VagrantServerFiles

HELP…. PLEASE
This should be easy, shouldn’t it????

    change, or add this line to php.ini:

     opcache.enable=0

    opcache is a php.ini.all type so it can be invoked in the php page like:

      ini_set (opcache.enable,0);

    by default, the value is 1 or “on” if not declared in php.ini

    Not certain, but if you’ve ruled out client side cache (which you have) and you don’t think you’re running a PHP-caching system (opcache/accelerator/etc) there are some Vagrant settings you might play around with:

    Either dropping the cache (manually I think this would look like: echo 1 > /proc/sys/vm/drop_caches)

    Or, possibly disabling sendfile() (see more on this answer: Vagrant/VirtualBox/Apache2 Strange Cache Behaviour)
