Fatal error: calling undefined stdClass method

Question

I get an error

Fatal error: calling the undefined method stdClass :: mysql_con () on .......... /.../includes/script/import.php on line 68.

Line 68 corresponds to:

if(!$ip2c->mysql_con())

I have a statement require_once()at the beginning of my script

What could be the problem?

thanks

Answer 1

Dusoft says this could mean:

• $ip2c the object does not exist

  What does not match is not because you get another error " Fatal error: Call to a member function mysql_con() on a non-object"

He also says this could mean:

• mysql_con The function is not part of the class you are trying to call.

  , , stdClass.

, quote:

• , , / , , PHP "stdClass" ( . )

, , :

• $ip2c , php , stdClass - .

  , .

 $ip2c = null;

 //php casts $ip2c to 'stdClass'
 $ip2c->foo = bah;

 //Fatal error: Call to undefined method stdClass::mysql_con() in...
 $ip2c->mysql_con();

.
