DEBUG OBJECT <key>

Consider using nginx for example in Laravel.
public data (ie. photo), upload api may be affected ?
sub folder ie. admin/ manager => is it ok or have to make different VirtualHost ?

Anyway, in some case it quite risky to migrate without fully understand problem, especially critical like photo access.

Try switch when have time, measure or experience speed change, caching etc.

Yeah I love mathematics. Remembering numerical algorithms.


To enable PHP in Apache add the following to httpd.conf and restart Apache:
    LoadModule php7_module /usr/local/opt/php@7.2/lib/httpd/modules/libphp7.so

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

Finally, check DirectoryIndex includes index.php
    DirectoryIndex index.php index.html

The php.ini and php-fpm.ini file can be found in:
    /usr/local/etc/php/7.2/

php@7.2 is keg-only, which means it was not symlinked into /usr/local,
because this is an alternate version of another formula.

If you need to have php@7.2 first in your PATH run:
  echo 'export PATH="/usr/local/opt/php@7.2/bin:$PATH"' >> ~/.bash_profile
  echo 'export PATH="/usr/local/opt/php@7.2/sbin:$PATH"' >> ~/.bash_profile

For compilers to find php@7.2 you may need to set:
  export LDFLAGS="-L/usr/local/opt/php@7.2/lib"
  export CPPFLAGS="-I/usr/local/opt/php@7.2/include"

OSX example:
$sqlite3 data/database.sqlite  # Symfony demo project

.help
.tables
select * from symfony_demo...;
