Good afternoon gurus and gurettes,
If I have a large app what is the difference, other than having a very large file, of doing this
switch($action){ /* several dozen cases to follow */ case "foo": writing out all of the code break; }
and this
switch($action){ /* several dozen cases to follow */ case "foo": include that will handle processing this case break; }
Correct me if I am wrong, but includes (and/or requires) will get all of the code in all of the cases regardless if the case is being processed. That being the case the code would essentially be the same length. Given that, would there be an efficieny issue?
I thought there was a difference for include and require for conditionals. But apparently not. :)
In any case doing the switch makes a difference as to which files will actually be parsed at runtime and the following code should illustrate (assuming you have class definitions in the files you want to include).
<?php
$php_classes = get_declared_classes(); $condition = 'test';
switch ($condition) {
case 'test':
include_once 'echo.php';
break;
case 'required':
require_once 'common.php';
break;
default:
echo 'Nothing was included!';
break;
}/** Now you can print the user defined classes to see if the code was included or not. */
print_r(array_diff(get_declared_classes(), $php_classes));
?>
