MAC runs PHP with built-in Apache

Background: After MAC 12, the built-in PHP is removed, and you need to install it yourself.
Preparation: First create your own certificate to sign the libphp.so file of PHP.

Step 1. Create a certificate

Use the extended key to use extension: code signature

After that, it has been defaulted to not need to be modified, and finally "created" directly, and it is successful when you see the picture below.

Step 2. Install PHP using Homebrew

brew install php

After the installation is complete, enter on the command line php -v to view the version of php. I installed version 8.1.8.

Step 3. Sign the libphp.so file

Enter on the command line, [email protected]modify it to the version you installed, and you can /opt/homebrew/opt/view it in the directory, mainly to libphp.so sign the file, PHPCAand the name of the signature file generated in step 1.

codesign --sign "PHPCA" --force --keychain ~/Library/Keychains/login.keychain-db /opt/homebrew/opt/[email protected]/lib/httpd/modules/libphp.so

After pressing Enter, a pop-up box will appear, just enter your own power-on password, as shown

in the figure below. After completion, the command line will display: /opt/homebrew/opt/[email protected]/lib/httpd/modules/libphp.so: replacing existing signature, which means success.

Step 4. Modify the Apache configuration file

sudo vi /etc/apache2/httpd.conf

Add the following line to the configuration file, PHPCA is the name of the certificate generated in the first step.

LoadModule php_module /opt/homebrew/opt/php/lib/httpd/modules/libphp.so "PHPCA"

Find DirectoryIndex
and modify it to

DirectoryIndex index.php index.html

Then restart apachectl on it

sudo apachectl start

The default PHP project file is in /Library/WebServer/Documentsthe directory, so put the self-developed file in this directory, and then open it in the browser http://localhost/testPage/to see it, or you can change the project path by yourself.
