L'exemple ci-dessus va afficher quelque chose de similaire à :

Array
(
    [0] => 00005b6b53610000000000000056
    [1] => 00005b6b53610000000000000057
)

Notes

Note:

A unique _id is generated by MySQL Server 8.0 or higher, as demonstrated in the example. The _id field must be manually defined if using MySQL Server 5.7.
