user defined error handling

[sunilvadranapu]

Hi,

  I am planning to write a PHP class for handling Errors/Warnings using trigger_error function.  Could any one explain what happens the below line gets executed?

 

    trigger_error("SQL:Non Timeout Error", E_USER_NOTICE);

 

I know we can process it using our own error handler with set_error_handler(). but  if didn't set user defined handler, what happens then? will it reporterror??

 

 

thanks in advance
