WP_User::remove_cap( string $cap )

Remove capability from user.

Parameters

$cap: (string) (Required) Capability name.

More Information

Changing the capabilities of a user is persistent, meaning the removed capability will stay in effect until explicitly granted.

This setting is saved to the database (in table wp_options, field 'wp_user_roles'), so you should run this only once, on theme/plugin activation and/or deactivation.

Source

File: wp-includes/class-wp-user.php

public function remove_cap( $cap ) {
		if ( ! isset( $this->caps[ $cap ] ) ) {
			return;

		unset( $this->caps[ $cap ] );
		update_user_meta( $this->ID, $this->cap_key, $this->caps );
		$this->get_role_caps();
		$this->update_user_level_from_caps();
