Q:

Where can I find the list of available built-in constants in PHP?

Hi everyone,
I hope you're doing well. I'm relatively new to PHP and I have a question regarding built-in constants in PHP. I've been trying to find a comprehensive list of all the available built-in constants, but so far, my search hasn't been very successful.

I know that PHP has a number of predefined constants, such as `E_ERROR`, `PHP_VERSION`, and `PHP_OS`, but I'm looking for a complete list that includes all the available ones. I believe having access to this list would greatly help me in understanding the language better and making my coding more efficient.

If anyone could point me in the right direction or provide a link to a reliable source where I can find such a list, I would be extremely grateful. Thank you in advance for your help and guidance!

Hey!
I completely understand your curiosity about the built-in constants in PHP. Back when I started learning PHP, I was also eager to explore all the available constants and their applications. Fortunately, I found a fantastic resource that helped me tremendously.

One of my go-to sources for PHP documentation is the PHP Manual. It's a comprehensive guide that covers a wide range of PHP topics, including built-in constants. The PHP Manual provides a detailed list of all the constants supported by PHP, giving you valuable insights into their purpose and usage.

To access the list of built-in constants, simply visit the PHP Manual website at https://www.php.net/manual/en/indexes.constants.php. There, you'll find an extensive collection of constants categorized alphabetically, making it easier for you to navigate through them.

I personally find the PHP Manual to be extremely reliable and user-friendly. It's always my first stop whenever I need information about PHP. I'm confident that it will be a great resource for you as well.

Good luck exploring the vast world of PHP constants! Feel free to reach out if you have any more questions. Happy coding!

Hey there!
I completely understand your curiosity about the available built-in constants in PHP. When I was starting out with PHP, I had the same question in mind. The good news is that PHP provides an official documentation that includes a comprehensive list of all the built-in constants.

I usually refer to the PHP manual for this purpose. They have a dedicated section for constants, where you can find all the information you need. The manual is well-organized and very helpful in understanding the purpose and usage of each constant.

Here is the link to the official PHP documentation on constants: https://www.php.net/manual/en/indexes.constants.php

Once you are on the page, you'll find an alphabetical index of all the constants. You can simply click on any constant name to get detailed information about it.

I hope this helps! Let me know if you have any more questions. Good luck with your PHP journey!
