This:

PHP код:

mysql_connect("127.0.0.1", "root", "", "server");
    if(mysql_errno(Database) == 0)
    {
        printf("[MySQL] The connection has failed.");
    }
    else
    {
        printf("[MySQL] The connection was successful.");
    } 


Should be,

PHP код:

new MySQL:Database; //On the Top

Database = mysql_connect("127.0.0.1", "root", "", "server");
    if(mysql_errno() == 0)
    {
         printf("[MySQL] The connection was successful.");
    }
    else
    {
           printf("[MySQL] The connection has failed."); 
    } 


mysql_errnno() will return -1 if there was any error. And 0 if there were no error. I sent you the link of wiki above.
