I am trying to learn PDO, now I have written this small code, but it gives me a serious error:

< P>

Fatal error: Call a member function at a non-object dot () ... 

  $ con = new mysqli ("127.0.0.1", "root", "", "csvdangercheck"); $ Query = $ con- & gt; ("Id,` var1`, `var2`) values ​​(" id,: var1,: var2) ";); $ query- & gt; bypass pattern (': id', $ id); $ query- & gt; BindParam (': var1', $ VAL1); $ Query- & gt; bindParam (': var2', $ val2); $ Query-> Executed ();   
 I Trying to use  print_r ($ con-> errorInfo ())  but  
  Fatal error:  Undefined method mysqli :: errorInfo ( ) ... can someone tell me what am I missing?
