Description
bool 
ssh2_auth_hostbased_file ( resource session, string username, string hostname, string pubkeyfile, string privkeyfile [, string passphrase [, string local_username]] )
     Authenticate using a public hostkey read from a file.  If privkeyfile
     is encrypted (which it should be), the passphrase must be provided.

| Example 1. Authentication using a public hostkey | 
<?php$connection = ssh2_connect('shell.example.com', 22, array('hostkey'=>'ssh-rsa'));
 
 if (ssh2_auth_hostbased_file($connection, 'remoteusername', 'myhost.example.com',
 '/usr/local/etc/hostkey_rsa.pub',
 '/usr/local/etc/hostkey_rsa', 'secret',
 'localusername')) {
 echo "Public Key Hostbased Authentication Successful\n";
 } else {
 die('Public Key Hostbased Authentication Failed');
 }
 ?>
