If you see the error "zsh: command not found: php" when you run the
php command in a terminal, it means that the
php command is unavailable in your current path. This can happen if you have not installed PHP on your system or if the PHP binary is not in a directory that is included in your
PATH environment variable.
To fix this error, you can either install PHP on your system or you can modify your
PATH environment variable to include the directory where the
php binary is located. For example, if PHP is installed in the
/usr/local/bin directory, you can add this directory to your
PATH variable by running the following command:
After modifying your
PATH variable, you should be able to run the
php command without any errors.
Note: If you are using the
zsh shell, you may need to modify your
.zshrc file instead of your
PATH variable to add the
php binary to your path permanently. You can add the
export command shown above to your
.zshrc file, which is located in your home directory.
How to install PHP
To install PHP on your system, you will need to download the PHP binary from the official PHP website and install it on your computer. The exact steps for installing PHP will vary depending on your operating system and the method you use to download and install PHP.
Here are the general steps for installing PHP on a computer running a Unix-like operating system like Linux or macOS:
Download the PHP binary from the official PHP website: https://www.php.net/downloads.php
Extract the downloaded file to a directory on your computer, such as
phpbinary to your
PATHenvironment variable. This will allow you to run the
phpcommand from any directory on your system.
Verify that PHP is installed correctly by running the
php -vcommand in a terminal. This should display the version of PHP installed on your system.
If you are using a Windows operating system, you can download a PHP installer from the official PHP website and use it to install PHP on your computer. The PHP installer will automatically add the
php binary to your
PATH environment variable, so you can run the
php command from any directory on your system.
Note: If you are using a Linux distribution, you may be able to install PHP using your distribution's package manager. For example, on Ubuntu, you can use the
apt-get command to install PHP:
sudo apt-get install php
This will install the latest version of PHP and any dependencies required by PHP. A package manager can make installing and managing PHP on your system easier.
How to install PHP using brew
To install PHP using Homebrew, you must have Homebrew installed on your system. Homebrew is a package manager for macOS that allows you to install and manage software on your computer easily.
If you do not have Homebrew installed, you can install it by following these steps:
Open a terminal on your computer.
Run the following command to install Homebrew:
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
- Follow the on-screen instructions to complete the installation of Homebrew.
Once you have Homebrew installed, you can use it to install PHP by running the following command in a terminal:
brew install php
This will install the latest version of PHP and any dependencies required by PHP. After the installation is complete, you can run the
php command to use PHP on your system.
Note: If you want to install a specific version of PHP, you can use the
brew search command to search for available versions of PHP, and then use the
brew install command to install the version you want. For example, to install PHP 7.4, you can run the following command:
brew install [email protected]
This will install PHP 8.1 and any dependencies required by PHP. You can then use the
php command to run PHP scripts and use PHP on your system.
