How to install a PHP environment on Mac

Before developing PHP, you need to set up a PHP environment. For Mac users, the process is relatively simple, and here are the detailed steps on how to install a PHP environment on Mac.

1. Installing Homebrew

Homebrew is one of the best package managers on Mac and can be used to install various open source software. Execute the following command from Terminal to install Homebrew:

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

2. Install PHP version

Homebrew The easiest way to install PHP is to use the following command :

brew install php

Executing this command will install the latest version of PHP in Homebrew. If you need to install other versions of PHP, you can use the following command to find it:

brew search php

Then you can install a specific version of PHP as needed, such as installing PHP 7.2 version:

brew install php@7.2

3. Install necessary extensions

After installing PHP, you may need to install some PHP extensions. These extensions may be database extensions, cache extensions, etc. Use the following command to install PHP extensions:

brew install php70-mcrypt php70-opcache php70-redis php70-xdebug php70-yaml

The above command installs five extensions: Mcrypt, Opcache, Redis, Xdebug and Yaml. You can choose to install other extensions based on your specific needs.

4. Configuring PHP

After installing the PHP environment, you need to configure it. Open the terminal and run the following command:

cd /etc
sudo nano php.ini

In this file you can modify some PHP configurations, such as file upload size limit, time zone, etc. Some commonly used settings are as follows:

upload_max_filesize = 2M
post_max_size = 8M
date.timezone = "Asia/Shanghai"

After saving the file, restart the Apache or Nginx web server to make the configuration take effect.

5. Testing whether PHP is working properly

Finally, you can test whether PHP is working properly by creating a PHP file. Assuming we have installed the Nginx web server, create a PHP file in the web root directory: /usr/local/var/www/info.php

Paste the following code into this file and save:

<?php
phpinfo();
?>

Now you can enter http://localhost/info.php in the browser. If everything goes well, the PHP information page will appear.

So far, you have successfully configured the PHP environment and can start PHP development.
