I've made this code, I hope it doesnt have error, but i've just made it for usecase like you wanted
Here is the code, I'll explain it below how this code works.
$authorization_url = "https://api.instagram.com/oauth/authorize/?client_id=".$instagram_client_id."&redirect_uri=".$your_website_redirect_uri."&response_type=code";
$username='ig_username';
$password='ig_password';

);
$ch = curl_init();
$cookie='/application/'.strtoupper(VERSI)."instagram_cookie/instagram.txt";
curl_setopt( $ch, CURLOPT_POST, 0 );
curl_setopt( $ch, CURLOPT_HTTPGET, 1 );
if($this->token!==null){
array_push($this->_defaultHeaders,"Authorization: ".$this->token);
}
curl_setopt( $ch, CURLOPT_HTTPHEADER, $this->_defaultHeaders);
curl_setopt( $ch, CURLOPT_HEADER, true);
curl_setopt( $ch, CURLOPT_SSL_VERIFYPEER, false );
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );
curl_setopt( $ch, CURLOPT_COOKIEFILE,getcwd().$cookie );
curl_setopt( $ch, CURLOPT_COOKIEJAR, getcwd().$cookie );
curl_setopt($this->curlHandle,CURLOPT_URL,$url);
curl_setopt($this->curlHandle,CURLOPT_FOLLOWLOCATION,true);
$result = curl_exec($this->curlHandle);
$redirect_uri = curl_getinfo($this->curlHandle, CURLINFO_EFFECTIVE_URL);
$form = explode('login-form',$result)[1];
$form = explode("action=\"",$form)[1];
// vd('asd',$form);
$action = substr($form,0,strpos($form,"\""));
// vd('action',$action);
$csrfmiddlewaretoken = explode("csrfmiddlewaretoken\" value=\"",$form);
$csrfmiddlewaretoken = substr($csrfmiddlewaretoken[1],0,strpos($csrfmiddlewaretoken[1],"\""));
//finish getting parameter
$post_param['csrfmiddlewaretoken']=$csrfmiddlewaretoken;
$post_param['username']=$username;
$post_param['password']=$password;
//format instagram cookie from vaha's answer https://stackoverflow.com/questions/26003063/instagram-login-programatically
preg_match_all('/^Set-Cookie:\s*([^;]*)/mi', $result, $matches);
$cookieFileContent = '';
foreach($matches[1] as $item)
{
$cookieFileContent .= "$item; ";
}
$cookieFileContent = rtrim($cookieFileContent, '; ');
$cookieFileContent = str_replace('sessionid=; ', '', $cookieFileContent);
$cookie=getcwd().'/application/'.strtoupper(VERSI)."instagram_cookie/instagram.txt";
$oldContent = file_get_contents($cookie);
$oldContArr = explode("\n", $oldContent);
if(count($oldContArr))
{
foreach($oldContArr as $k => $line)
{
if(strstr($line, '# '))
{
unset($oldContArr[$k]);
}
}
$newContent = implode("\n", $oldContArr);
$newContent = trim($newContent, "\n");
file_put_contents(
$cookie,
$newContent
);
}
// end format

curl_setopt($ch, CURLOPT_HTTPHEADER, $arrSetHeaders);

curl_setopt($ch, CURLOPT_REFERER, $redirect_uri);
curl_setopt($ch, CURLOPT_POST, true);

}
var_dump($page);
Step 1:
We need to get to the login page first.
We can access it using curl get, with CURLOPT_FOLLOWLOCATION set to true so that we will be redirected to the login page, we access our application instagram authorization url
$authorization_url = "https://api.instagram.com/oauth/authorize/?client_id=".$instagram_client_id."&redirect_uri=".$your_website_redirect_uri."&response_type=code";
$username='ig_username';
This is step one from this Instagram documentation here
Now the result of the first get curl we have the response page and its page uri that we store at $redirect_uri, this must be needed and placed on referer header when we do http post for login.
After get the result of login_page, we will need to format the cookie, I know this and use some code from vaha answer here vaha's answer
Step 2:
After we get the login_page we will extract the action url , extract csrfmiddlewaretoken hidden input value.
After we get it, we will do a post parameter to login.
We must set the redirect uri, and dont forget the cookiejar, and other header setting like above code.
After success sending the parameter post for login, Instagram will call your redirect uri, for example https://www.yourwebsite.com/save_instagram_code at there you must use or save your instagram code to get the access token using curl again ( i only explain how to get the code :D)
I make this in a short time, I'll update the code which I have tested and work if i have time, Feel free to suggest an edit of workable code or a better explanation.
