Question

The PSR-0/1/2-syntax checker on phphint.org gives this message

The first parameter of a multi-line function declaration must be on
the line after the opening bracket 

on this code:

// class autoloader for PHP 5.3+
spl_autoload_register( function ($class) {
    include('classes/' . $class . '.class.php');
});

I tried a lot, but never got this little piece of code PSR-0/1/2-save.
How would a solution look like (or is the analyzer on phphint too strict ?) ?

Answer 1

I fixed this by myself, but the solution is extremely ugly.

spl_autoload_register( function (
    $class
) {
    include('classes/' . $class . '.class.php');
}
);

Maybe the PSR-guys should think about their weird syntax.
The correct solution looks like this, even if it is a step backwards.

// autoload function (it's NOT "__autoload", __autoload is
// DEPRECATED since PHP 5.4!)
function autoload($class) {
    include('classes/' . $class . '.class.php');
}

// class autoloader for PHP 5.3+, registers the function that's used if a class/file
// is not found (=autoloader)
spl_autoload_register('autoload');
