Error messages

Hi,

One question.

I set to php.ini this

error_reporting=E_ALL & ~E_NOTICE

to be a list of error messages and some warnings/tips on the code written.

All good, but if I have code like

------------------------
function foo(string $x)
{
echo($x);
}

foo("hi");
------------------------


I got this error


------------------------
Catchable fatal error: Argument 1 passed to foo() must be an instance of
string, string given, called in E:\Work\php\phpFramework\test.php on line 8
and defined in E:\Work\php\phpFramework\test.php on line 3
------------------------

!!!but... is not "hi" a string???
What kind of *Catchable fatal error* would be this???

:)

I write foo(string $x) exactly to say that the function need a string!


Thanks

The type hinting is for objects and arrays only. So, with the code
you've got, PHP expects the argument to be an object of class "string"
rather than the primitive string. Take that out of your function
declaration and it should be fine.

???

I tryied with

$a = "hi";
foo($a);

but is the same... at this point I don't understand how to remove this kind
or error message.

so I should remove the type for the parameter?
This don't seems a good solution :(

I tryied this kind of error_reporting because else if I declare for my fault
2 time the foo() function, the script is interrupted (cannot be interpreted)
and I got the error message that the function is duplicated.

I was not able to leave the useful "duplicated error message" but removing
the useless *catchable* FATAL (???) error :(

Please read the manual about Type Hinting:

Should be E_ALL.

Should be

function foo($x) {
echo $x;
}

This seems a really bad implementation of php.
Php let you indicate the data type to be used and then considers it as a
syntax error???

Good thing...

I find the best to write good code:

E_ALL | E_STRICT & ~E_RECOVERABLE_ERROR


The classic problem is that the php online documentation is really
incomplete and confused: the E_RECOVERABLE_ERROR is not documented, but I
can find something more in the donloaded documentation or in some unofficial
web site.

It allows you to indicate a *USER DEFINED* data type. Not a built-in
datatype.

The manual is pretty clear about that:

| Type Hints can only be of the object and array (since PHP 5.1) type.
| Traditional type hinting with int and string isn't supported.

Or in other words - it works for complex types, but not for scalars.

IMHO that's even worse than supressing E_NOTICE errors. _All_ errors
should be shown and handled while developing, which means

E_ALL

or better

E_ALL | E_STRICT
