get_user_meta( int $user_id, string $key = '', bool $single = false )

Retrieve user meta field for a user.

Parameters

$user_id

(int) (Required) User ID.

$key

(string) (Optional) The meta key to retrieve. By default, returns data for all keys.

Default value: ''

$single

(bool) (Optional) Whether to return a single value. This parameter has no effect if $key is not specified.

Default value: false

Return

(mixed) An array if $single is false. The value of meta data field if $single is true. False for an invalid $user_id.

More Information

Please note that if the meta value exists but is empty, it will return an empty string (or array) as if the meta value didn’t exist. This might cause unexpected behaviors in your code when you empty the user meta, your code can try to use add_user_meta instead of update_user_meta thinking the user does not have meta created yet.
