Call the functions added to a filter hook. See the Plugin API for a list of filter hooks.
The callback functions attached to filter hook $tag are invoked by calling this function. This function can be used to create a new filter hook by simply calling this function with the name of the new hook specified using the $tag parameter.
<?php apply_filters($tag, $value); ?>
(mixed) The result of $value after all hooked functions are applied to it.
Note: The type of return should be the same as the type of $value: a string or an array, for example.
