print_r($result);

the code is not working !!
is the any specific plugin required , please???

Works fine, you just need https://github.com/wp-api/basic-auth installed and an appropriate user / password set up.

thanks for replying :)
I've installed it and activate.
I've added a new user from wp dashboard and still the code doesn't work !!

Anyone know of a snippet that does this using auth cookies instead of basic auth?

Use the simple jwt-auth plugin, but use this fork https://github.com/jonathan-dejong/simple-jwt-authentication/wiki/Documentation

does not work for https site

Worked for me. As is. On an HTTPS site.
Thanks Andrew.

Hello. thanks you. worked for me.
generate an application passwords and email credentials.
HTTPS
PHP 7.4.21 (cli) (built: Jul 2 2021 15:33:47) ( NTS )

Saludo, Andres.

Thanks Andrew works like magic 👍

This the one of the few examples on the web to show how to actually interact with WordPress rest api with PHP and curl :)

If you add also the fields categories, tags, meta and featured_media it becomes PERFECT!
