unexpected T_INCLUDE_ONCE

jtbaker

can anyone tell me if I'm interpreting the PHP manual correctly? Is it true that you cannot use an include_once(""); in a case inside a switch conditional? I have done so and am getting the error message mentioned in the subject above. I'm virtually certain that all my syntax is correct except for this issue...

Thanks! 🙂

you are able to use it inside a switch statement. post the code and ill see whats wrong.

sorry to have bothered everyone, especially drew010... i found a syntax error while posting the code... ironically, I had already put it in another text editor to get a "fresh look" at it and didn't notice it then... while investigating possibilities I read in the PHP manual:

"The case expression may be any expression that evaluates to a simple type, that is, integer or floating-point numbers and strings. Arrays or objects cannot be used here unless they are dereferenced to a simple type."

Does this mean that objects cannot be instantiated inside a case? Can arrays not be utilized inside a case?

Thank you.

They can be instantiated in a case, what they are saying is you cant do something like this:

switch($array)
or
switch($myObject)

but you can do

switch($array[0])
as long as what is held inside $array[0] is an int, float or string.

By "case expression" I think is meant the particular line that starts with "case" and end with ":".

case 7: // <- case expression
    // normal code here
    break;

$var = new myclass; // $var is an object
$var = 2; // $var is an integer

switch ( $var ) {

case 2 : // if integer 2 or
case TRUE : // boolean TRUE
// do this
$str = $obj->myclass_function();
echo $str;

case "name" : // string
// do that
case 1.23 : // float
// do whatever
default :
// else do this

}

As I get it,
you can not use array or object as $var and test this using 'case'
but simple string, float number and integer and FALSE / TRUE is allowed

But in
// do this
you can use php as normal
also use object like $this->func();
to call class functions
