是的，你可以在macOS 上安裝PHP。使用Homebrew 安裝PHP 是最簡(jiǎn)單可靠的方法：1. 安裝Homebrew；2. 添加shivammathur/php 倉(cāng)庫(kù)；3. 安裝指定版本如php@8.2 並全局鏈接。接著配置Web 服務(wù)器運(yùn)行PHP 文件：macOS 自帶Apache，需啟動(dòng)並配置加載PHP 模塊後將PHP 文件放入指定目錄；或選擇Nginx 配合PHP-FPM 使用。常見(jiàn)問(wèn)題包括路徑錯(cuò)誤需修改PATH、權(quán)限問(wèn)題用chown/chmod 處理，以及可同時(shí)安裝多個(gè)PHP 版本通過(guò)brew services 管理。掌握這些步驟和注意事項(xiàng)即可順利完成安裝。

Yes, you can absolutely install PHP on macOS — and it's not as complicated as it might sound. macOS comes with a version of PHP pre-installed (or at least used to in earlier versions), but it's often outdated or completely removed in newer releases like macOS Ventura and Sonoma. So if you want to run PHP locally for development, you'll need to install it yourself.

Here's how to do it in a way that works well and doesn't leave you guessing what went wrong.

Use Homebrew to Install PHP

Homebrew is the easiest and most reliable way to install PHP on macOS. If you don't have it yet, install Homebrew first by running this command in your terminal:

 /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Once that's done, tap into the PHP repository:

 brew tap shivammathur/php

Then install the version of PHP you want. For example, to install PHP 8.2:

 brew install shivammathur/php/php@8.2

After installation, link the version so it's available globally:

 brew link --force --overwrite php@8.2

You can check the installed version with:

 php -v

Set Up a Web Server (Apache or Nginx)

PHP alone isn't enough — you need a web server to actually run PHP files through a browser.

Apache (built-in)

macOS comes with Apache built in. Start it with:

 sudo apachectl start

Test it by going to http://localhost in your browser. You should see a message saying “It works!”

To make it serve PHP files:

• Put your .php files in /Library/WebServer/Documents/
• Make sure PHP is enabled by editing Apache's config file ( /etc/apache2/httpd.conf ) and uncommenting or adding:

 LoadModule php_module /usr/local/opt/php@8.2/lib/httpd/modules/libphp.so

Then restart Apache:

 sudo apachectl restart

Or use Nginx

If you prefer Nginx, install it via Homebrew:

 brew install nginx

Configure it to work with PHP-FPM (which also gets installed when you install PHP). The setup is slightly more involved, but there are plenty of guides online tailored for macOS.

Common Issues and Fixes

• Path problems : After installing PHP, your terminal might still show the old version. Check with which php . If it points to /usr/bin/php , update your PATH in ~/.zshrc or ~/.bash_profile :

   export PATH="/usr/local/opt/php@8.2/bin:$PATH"
  export PATH="/usr/local/opt/php@8.2/sbin:$PATH"

  Then reload the shell:

   source ~/.zshrc

• Permissions : When setting up web directories, you may run into permission errors. Use sudo chown or chmod carefully to fix them.

• Multiple PHP versions : You can install multiple PHP versions side by side. Use brew services to manage which one runs.

Wrap-up

Installing PHP on macOS boils down to using Homebrew, linking the right version, and pairing it with a web server. It's not hard once you know the steps, but small issues like path settings or Apache config can trip you up. Keep an eye out for those, and you'll be good to go.

基本上就這些。
