stop current function and start next

[eluser]KeyStroke[/eluser]
You could try this:

Code:

if (ereg("([0-9]{2})/([0-9]{2})/([0-9]{4})", $date1)) {          
Echo "its correct";            
}else{
$this->_function_b();
return; // an empty return - it basically stops the function from executing the rest of the code.
}

May I ask why are you doing this though? it seems strange to me.
