Function Name: wp_parse_args

Explanation: The wp_parse_args function in WordPress is used to merge user-defined arguments with default arguments. This function is commonly used when creating functions that require a set of arguments, with some of them being optional and having default values. By using wp_parse_args, developers can easily override default values with user-defined arguments if they are provided.

Example Usage:

function custom_function($args = array()) {
    $defaults = array(
        'param1' => 'default_value1',
        'param2' => 'default_value2',
        'param3' => 'default_value3'

    $args = wp_parse_args($args, $defaults);

    // Now $args contains merged values of user-defined arguments and default arguments

In the example above, the custom_function takes an array of arguments as a parameter. By using wp_parse_args, the function sets default values for the arguments and then merges them with the user-defined arguments provided. This allows for flexibility in customizing the behavior of the function based on the arguments passed to it.
