In order to create a simple category use:

wp_create_category( 'My category name' );

To create a category that is a child of the category with ID = 6, you must specify the second parameter:

wp_create_category( 'Child of My Category', 6 );

To get id of category created and put value in variable:

$cat_id = wp_create_category( 'Child of My Category', 6 );
0

#2 Check if a category was created

$cat_id = wp_create_category( 'Miscellaneous' );

if( $cat_id ){
	echo 'Created';
}
else {
	echo 'Not created';
}
