No, you include all the class sources at the beginning. Then you instantiate
the appropriate one as you need it, i.e.
while (odbc_fetch_row($result) || $done) {
// Get the file format here, then
$myObject = null;
switch($fileFormat) {
case "format1" :
$myObject = new MyClass1();
break;
case "format2":
$myObject = new MyClass2();
break;
// etc.
}
if (myObject) {
$myObject->doSomething($odbc_result); // Call function(s) in the class
}
Each class will handle one file format and all classes will have the same
function names. Just determine the file format, instantiate the appropriate
class and let it do the work.
