Sets an array in depth based on a path of keys.
Description
It is the PHP equivalent of JavaScript’s lodash.set() and mirroring it may help other components retain some symmetry between client and server implementations.
Example usage:
$input_array = array();
_wp_array_set( $input_array, array( 'a', 'b', 'c', 1 ) );
$input_array becomes:
array(
'a' => array(
'b' => array(
'c' => 1,
),
),
);Parameters
$input_arrayarrayrequired- An array that we want to mutate to include a specific value in a path.
$patharrayrequired- An array of keys describing the path that we want to mutate.
$valuemixedoptional- The value that will be set.
Default:
null

}

$path_element = $path[ $i ];

! array_key_exists( $path_element, $input_array ) ||
! is_array( $input_array[ $path_element ] )
) {
$input_array[ $path_element ] = array();
}
$input_array = &$input_array[ $path_element ];
}
$input_array[ $path[ $i ] ] = $value;
