Is it possible to get user\'s steamID by his nickname? I didn\'t find solution in steam API documentation. The only one thing that I found is an old post on http://dev.dota2.com
Using PHP and the Steam Condenser project, you can accomplish this.
require_once('steam/steam-condenser.php');
$playername = 'NAMEOFPLAYER';
try
{
$id = SteamId::create($playername);
}
catch (SteamCondenserException $s)
{
// Error occurred
}
echo $id->getSteamId;
There are usage examples in the wiki for the project if you need more information.
