Installing PHP 7.4 on MacOS may seem like a daunting task, but thanks to the advancements in software and technology, the process has become easier than ever. This article will take you through the steps required to install PHP 7.4 on MacOS.
Firstly, it is important to note that MacOS comes preinstalled with PHP 7.3. So, in order to upgrade to PHP 7.4, we need to install it manually. There are several ways to install PHP 7.4 on MacOS, but we will discuss two methods: using Homebrew and using a precompiled binary.
Method 1: Using Homebrew
Homebrew is a package manager for MacOS that simplifies the installation of software. To install PHP 7.4 using Homebrew, follow these steps:
Step 1: Install Homebrew
If you don’t have Homebrew installed on your MacOS, you can install it by running the following command in the Terminal:
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
This command will install Homebrew on your MacOS.
Step 2: Install PHP 7.4
After installing Homebrew, run the following command in the Terminal to install PHP 7.4:
brew install php@7.4
This command will download and install PHP 7.4 along with all the necessary dependencies.
Step 3: Restart Apache
If you are using Apache as your web server, you need to restart it to load the new PHP version. Run the following command to restart Apache:
sudo apachectl restart
Step 4: Verify the Installation
To verify that PHP 7.4 is installed and working correctly, run the following command in the Terminal:
php -v
This command will display the PHP version installed on your MacOS.
Method 2: Using a Precompiled Binary
If you don’t want to use Homebrew, you can download and install a precompiled binary of PHP 7.4. Here are the steps to do so:
Step 1: Download the Binary
Go to the official PHP website and download the precompiled binary for MacOS. Make sure you download the version of PHP that matches your MacOS architecture (either 64-bit or 32-bit).
Step 2: Extract the Binary
Extract the downloaded binary to a folder on your computer using a decompression tool like 7-Zip or WinZip.
Step 3: Move the Binary to the /usr/local/bin Directory
Open the Terminal and run the following command to move the PHP binary to the /usr/local/bin directory:
sudo mv ~/Downloads/php-7.4.0/bin/php /usr/local/bin/php
Make sure you replace ~/Downloads/php-7.4.0/bin/php with the path to your PHP binary.
Step 4: Restart Apache
If you are using Apache as your web server, you need to restart it to load the new PHP version. Run the following command to restart Apache:
sudo apachectl restart
Step 5: Verify the Installation
To verify that PHP 7.4 is installed and working correctly, run the following command in the Terminal:
php -v
This command will display the PHP version installed on your MacOS.
Code Examples
Now that you have installed PHP 7.4 on your MacOS, you can start developing your PHP applications. Here are some code examples to get you started:
Example 1: Hello World
Create a new PHP file called hello.php with the following code:
<?php
echo "Hello World!";
?>
Save the file in the /Library/WebServer/Documents directory (or any other directory that your web server is configured to use).
Open your web browser and go to http://localhost/hello.php. You should see the message “Hello World!” displayed on the page.
Example 2: Variables
Create a new PHP file called variables.php with the following code:
<?php
$name = "John";
$age = 30;
echo "My name is $name and I am $age years old.";
?>
Save the file in the /Library/WebServer/Documents directory.
Open your web browser and go to http://localhost/variables.php. You should see the message “My name is John and I am 30 years old.” displayed on the page.
Example 3: Conditional Statements
Create a new PHP file called conditional.php with the following code:
<?php
$temperature = 25;
if ($temperature >= 30) {
echo "It's too hot!";
} elseif ($temperature < 20) {
echo "It's too cold!";
} else {
echo "It's the perfect temperature.";
}
?>
Save the file in the /Library/WebServer/Documents directory.
Open your web browser and go to http://localhost/conditional.php. You should see the message “It's the perfect temperature.” displayed on the page, assuming the temperature variable is set to 25.
Conclusion
Installing PHP 7.4 on MacOS is a simple and straightforward process. You can either use Homebrew or a precompiled binary to get the job done. Once installed, you can start developing your PHP applications using code examples like the ones provided in this article. Happy coding!
In addition to the previous topics mentioned, there are a few more things to consider when it comes to installing PHP 7.4 on MacOS and working with it.
One important consideration is the use of a PHP development environment. While it is possible to write PHP code in a simple text editor and run it using a web server, a PHP development environment can greatly simplify the development process and provide useful tools such as debugging and code completion.
One popular PHP development environment for MacOS is PhpStorm, which provides a user-friendly interface and a wide range of features to assist with PHP development. Other options include Visual Studio Code, Sublime Text, and Atom.
Another important consideration is the use of a PHP package manager such as Composer. Composer is a tool for managing PHP packages and their dependencies, and can greatly simplify the process of integrating third-party libraries and frameworks into your PHP project.
To install Composer on MacOS, you can follow the steps outlined on the Composer website. Once installed, you can use Composer to easily add new packages to your PHP project and keep them up-to-date.
Finally, it is worth noting that PHP 7.4 includes several new features and improvements over previous versions of PHP, including improved type hints, support for typed properties, and an improved garbage collector. These new features can greatly enhance the performance and functionality of your PHP code, and it is worth taking the time to familiarize yourself with them.
In conclusion, installing PHP 7.4 on MacOS is a straightforward process that can greatly enhance your PHP development experience. By using a PHP development environment such as PhpStorm, a package manager such as Composer, and the new features of PHP 7.4, you can streamline your development workflow and build better PHP applications.
