Echo after Filtering

echo apply_filters( $tag, $value );

Get Filtered

$myvar = apply_filters( $tag, $value );

Additional Filter Arguments

$myvar = apply_filters( $tag, $value, $param, $otherparam );

For example:

$myvar = apply_filters( 'example_filter', 'filter me', 'arg1', 'arg2 ');

With the_title filter

$my_custom_title = apply_filters('the_title', '  My Custom Title (tm)  ');
$my_custom_title will now contain 'My Custom Title ™', since the_title filter applies wptexturize() and trim(), among others.

One fundamental argument that is easy to miss is specifying the number of arguments. Most filters have only one argument and so people drop the argument from add_filter.

The 3, below is very important.
```
add_filter( 'example_filter', 'example_callback', 10, 3 );
```
Otherwise you get the following error, such as this StackOverflow question(http://stackoverflow.com/questions/24198086/missing-argument-2-for-the-function-in-wordpress):

Missing argument 2 for example_callback()

Something that is not obvious from reading this function’s definition and description is that if add_filter( 'filter_name', 'filter_function' ) is never called/executed in code, the use of apply_filters( 'filter_name', $value ) will return the value of $value by default.

I noticed a call to apply_filters( 'my_filter', ... ) in my theme’s functions.php file and couldn’t find a similar add_filter( 'my_filter', ... ) call anywhere else and was confused about this (I’m still wrapping my head around filters/hooks).

More detail on this can be seen in the example found on this page: https://docs.presscustomizr.com/article/26-wordpress-actions-filters-and-hooks-a-guide-for-non-developers at the section about Filters.

If someone would like to give permission to other developers to change their plugin or theme function value without touching the core code then should use apply_filters

For example –
```
$value = 'Hello world!';
echo apply_filters( 'wpdocs_hook_name', $value, $arg1, $arg2 ); // You can pass arguments also
```
Now how 3rd party developer will work using this hook name? Using the add_filter developer can change the $value variable.
Please follow below –
```
function wpdocs_func_name( $value, $arg1, $arg2 ) {
	return 'Hi Jack!'; 
}
add_filter( 'wpdocs_hook_name', 'wpdocs_func_name', 10, 3 ); // Must specify the arguments number if you use multiple arguments
```
Now the result will show “Hi Jack!” instead of “Hello world!” and it has changed the $value variable dynamically without touching the core file.

The second line in the description is technically incorrect:

“It is possible to create new filter hooks by simply calling this function…”

apply_filters doesn’t create filter hooks. Read for https://stackoverflow.com/q/72161547/3429430 details
