this seem not to work and I don't know why? you can create static closures inside non static methods, why not vice versa?
class RegularClass {
private $name = 'REGULAR';
}
class StaticFunctions {
public static function doStuff()
{
$func = function ()
{
// this is a static function unfortunately
// try to access properties of bound instance
echo $this->name;
};
$rc = new RegularClass();
$bfunc = Closure::bind($func, $rc, 'RegularClass');
$bfunc();
}
}
StaticFunctions::doStuff();
// PHP Warning: Cannot bind an instance to a static closure in /home/codexp/test.php on line 19
// PHP Fatal error: Using $this when not in object context in /home/codexp/test.php on line 14
As i said on my comment it seems that you can't change the "$this" from a closure that comes from a static context. "Static closures cannot have any bound object (the value of the parameter newthis should be NULL), but this function can nevertheless be used to change their class scope." I guess you will have to make something like this:
class RegularClass {
private $name = 'REGULAR';
}
class Holder{
public function getFunc(){
$func = function ()
{
// this is a static function unfortunately
// try to access properties of bound instance
echo $this->name;
};
return $func;
}
}
class StaticFunctions {
public static function doStuff()
{
$rc = new RegularClass();
$h=new Holder();
$bfunc = Closure::bind($h->getFunc(), $rc, 'RegularClass');
$bfunc();
}
}
StaticFunctions::doStuff();
