How Do I Add a Function PHP File to WordPress?

If you want to add a function PHP file to WordPress, you first need to create a folder for it in your WordPress install. Once you’ve created the folder, you can copy the function file into it.

Next, you’ll need to add a line to your WordPress configuration file to tell WordPress where to find the function file. To do this, open up your WordPress configuration file (usually located at wp-config.php) and add the following line:.

‘function_file’ => ‘/path/to/my/function/file.php’,

Once you’ve added the line, you can access the function file from within WordPress by using the function_file() function.
