PHP libcurl socks5 not working - php

Question

I try to connect to socks5 proxy using libcurl, however I receive the answer SOCKS: authentication failed. I also tried to connect to the proxy server through a Powershell script with cURL – it works, so the proxy server is available and my login and password are correct. I tried a lot of solutions... But connection via PHP-script still does not work.
PHP version – 5.4, cURL version – 7.19. What can I do?
[UPDATE] Here is my current code. I want to send message with my Telegram bot :)
$proxy = '<hostname>:<port>';
$proxy_auth = '<username>:<password>';
$url = 'https://api.telegram.org/bot<botID>/sendMessage?'.'chat_id='.$chat_id.'&parse_mode='.$parse_mode.'&text='.'test';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_PROXYTYPE, CURLPROXY_SOCKS5);
curl_setopt($ch, CURLOPT_PROXY, $proxy);
curl_setopt($ch, CURLOPT_PROXYUSERPWD, $proxy_auth);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_HEADER, true);
$curl_scraped_page = curl_exec($ch);
$error = curl_error($ch);
echo $error;
echo $curl_scraped_page;
curl_close($ch);

Here is the complete answer for anyone else having the same issue.
//Curl setup
$url = "https://google.com";
$proxy = "10.23.2.2:8080";
$password = "username:secret_passowrd";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_PROXYTYPE, CURLPROXY_SOCKS5);
curl_setopt($ch, CURLOPT_HEADER, true);
//proxy's address
curl_setopt($ch, CURLOPT_PROXY, $proxy);
//proxy's password
curl_setopt($ch, CURLOPT_PROXYUSERPWD, $password);
//in order to follow redirects.
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
//in order to use the result of the query
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
//run query
$curl_scraped_page = curl_exec($ch);
$error = curl_error($ch);
echo $error;
echo $curl_scraped_page;
curl_close($ch);
Hope that helps.
