要運行PHP腳本，需根據用途選擇合適的環(huán)境。1. 本地運行：使用XAMPP、WAMP或MAMP等集成包搭建環(huán)境，將PHP文件放入htdocs目錄并通過瀏覽器訪問http://localhost/yourfile.php執(zhí)行；Linux用戶可檢查并用sudo apt安裝PHP。2. 命令行運行：適用于自動化任務，確保PHP加入PATH后，在終端進入腳本目錄并執(zhí)行php script.php。3. 在線測試：通過3v4l.org、phptester.net等平臺快速測試代碼片段，適合學習和分享但不適合開發(fā)完整應用。正確選擇方法可讓PHP運行變得簡單高效。

PHP scripts aren't like HTML files — you can’t just double-click and run them. They need a special environment to work properly. If you're trying to execute PHP code on your own machine or a server, here's how to get it done the right way.

Setting up a local PHP environment

Before running any PHP script, you need a working environment that includes PHP itself, and optionally a web server like Apache or Nginx. The easiest way for beginners is using a package like XAMPP, WAMP (for Windows), or MAMP (for macOS).

• XAMPP is cross-platform and comes with everything pre-configured
• Just install, start the Apache server, and drop your .php file into the htdocs folder
• Then visit http://localhost/yourfile.php in your browser

If you're on Linux, you might already have PHP installed. You can check by opening a terminal and typing:

php -v

If not, use your package manager to install it (e.g., sudo apt install php on Ubuntu-based systems).

Running PHP from the command line

You don’t always need a browser to run PHP. If you're writing a script meant for tasks like cron jobs or data processing, you can execute it directly in the terminal or command prompt.

Make sure PHP is available globally. On most systems, this means adding it to your PATH during installation or later. Once set up:

• Save your PHP script as something like script.php
• Open a terminal or CMD and navigate to the folder containing the file
• Run:

  php script.php

  This method skips the web server entirely and outputs results straight to the console. It’s fast and useful for automation.

  Using an online PHP runner (for quick tests)

  Sometimes you just want to test a small piece of code without setting up anything locally. Online tools like 3v4l.org, phptester.net, or JDoodle let you paste and run PHP snippets instantly.

  These are great for:

  • Learning basic syntax
  • Testing compatibility across different PHP versions
  • Sharing quick examples with others

  But they’re not suitable for full apps or sensitive data. Also, no file system or database access, so real development still needs a proper setup.

  Running PHP scripts isn’t complicated once you know what environment you need. Whether you're building a website, automating tasks, or just learning, there’s a method that fits. Mostly, it just takes a bit of setup and knowing which tool to use when.
