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.
