How to use the php that brew installed?

You have to make your Apache use the PHP that you just downloaded.

• Open your httpd.conf (mine is at /etc/apache2/httpd.conf) and look for the line that loads the PHP module, something like:

  LoadModule php5_module path/to/php

• Then, make it point to the PHP that brew installed for you with mcrypt support. Mine was at this path. Yours can vary depending on the PHP version that you installed.

  /usr/local/Cellar/php54/5.4.21/libexec/apache2/libphp5.so

• Finally you will need to restart your Apache server to load the new configuration:

  sudo apachectl restart

According to the contributors of the Homebrew php formula...

The contributors of the Homebrew php formula give the following instructions. The exact instructions reproduced here install php7.4. Substitute the php version you need.

(Avoid "special" ways of accomplishing your objective; they are often problematic. "Official" approaches are more likely to give you a predictable, maintainable setup.)

$ brew search php // since php can be installed by homebrew but be missing from your PATH, review the list of php versions available through homebrew; a checkmark next to a version indicates one is installed$ brew install php@7.4$ echo 'export PATH="/usr/local/opt/php@7.4/bin:$PATH"' >> ~/.zshrc // add the alias to your path (issues you are using zsh, the default now for macOS); see comments output during installation$ source ~/.zshrc // reload . zshrc to use the new settings immediately

The contributors of the formula also provide the following instructions for enabling PHP in Apache:

To enable PHP in Apache add the following to httpd.conf and restart Apache:

   LoadModule php_module /usr/local/opt/php/lib/httpd/modules/libphp.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/7.4/

These instructions for enabling PHP in Apache appear in stdout when you install php. Alternatively in Terminal use brew info php or visit the Homebrew PHP formula page

Can't comment on stackoverflow yet due to my lack of experience but to add to the above answer is correct. Just an additional comment to find the correct path:

run:

brew info php54

or which ever version u have installed and it will show you the path:

To enable PHP in Apache add the following to httpd.conf and restart Apache:    LoadModule php5_module    /usr/local/opt/php54/libexec/apache2/libphp5.so
