Well I’m studying cURL, because I want to make an application with Twitter using login form and password... yesterday I did this question and was very well answered, based on this I am studying cURL, then I have the following code:
<?php
if (isset($_POST['ttrSignin'])) {
$ttrUsername = trim(filter_input(INPUT_POST, 'ttrUsername'));
$ttrPassword = trim(filter_input(INPUT_POST, 'ttrPassword'));
$ttrTweet = trim(filter_input(INPUT_POST, 'ttrTweet'));
if (empty($ttrUsername)) {
$error[] = 'Insira seu nome de usuário do Twitter.';
} elseif (empty($ttrPassword)) {
$error[] = 'Insira sua senha do Twitter.';
} elseif (empty($ttrTweet)) {
$error[] = 'Insira seu Tweet.';
} else {
# The Twitter API Address
$url = 'https://api.twitter.com/1.1/statuses/update.json';
# Versão alternativa do JSON
# $url = 'https://api.twitter.com/1.1/statuses/update.json'
# Configure e execute o processo de curl
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 2);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, 'status=' . $ttrTweet);
curl_setopt($ch, CURLOPT_USERPWD, $ttrUsername . ':' . $ttrPassword);
$buffer = curl_exec($ch);
curl_close($ch);
//var_dump($buffer);
}
# Verifique o sucesso ou o fracasso
if (empty($buffer)) {
$error[] = 'Não foi possível conectar-se ao Twitter.';
} else {
$success[] = 'Tweet postado via Twitter API.';
}
}
?>

When executed it shows the message:
Unable to connect to Twitter.
When giving a var_dump($buffer);, he returns me the following:
C: wamp64 www twitterlogin index.php:31:Boolean false
What is wrong?
I think that for security reasons Twitter no longer allows this. I think
