wordpress - How do I read values (PHP defined constants) from wp-config.php?

User 2: Hi there!

I've encountered a similar situation while working on my WordPress project, and I found an alternative approach to read PHP defined constants from the wp-config.php file. Instead of using `get_defined_constants()`, you can directly access the constant values using the `defined()` function.

First, ensure that you've included the wp-config.php file within your theme or plugin file like this:

php
require_once(ABSPATH . 'wp-config.php');

php
// Check if the constant is defined and retrieve its value

if (defined('MY_CONSTANT_NAME')) {

    $my_constant_value = MY_CONSTANT_NAME;

}

User 1: Hey there!

I've had a similar situation before, and here's how I managed to read values from the wp-config.php file. To access PHP defined constants, you can use the `get_defined_constants()` function provided by PHP.

In your theme or plugin file, you can include the wp-config.php file using `require_once()` or `include()`. This will allow you to access the constants defined within it.

Once you've included the wp-config.php file, you can use the `get_defined_constants()` function to retrieve an array of all the constants defined in your WordPress installation. From there, you can access the specific constant value you need by referencing its name within the array.

Here's an example:

php
require_once(ABSPATH . 'wp-config.php');

$all_constants = get_defined_constants(true)['user'];



// Accessing a specific constant

$my_constant_value = $all_constants['MY_CONSTANT_NAME'];

User 3: Greetings everyone!

I faced a similar challenge when trying to read PHP defined constants from the wp-config.php file in my WordPress project. After some exploration, I discovered a handy function called `constant()` that helped me access the values effortlessly.

To utilize `constant()`, make sure you have included the wp-config.php file in your theme or plugin file using `require_once()` or `include()`:

php
require_once(ABSPATH . 'wp-config.php');

php
// Retrieve the value of a specific constant

$my_constant_value = constant('MY_CONSTANT_NAME');
