Closure::bind — Duplicates a closure with a specific bound object and class scope
$closure
, object $newthis
[, mixed $newscope
= 'static'
] )This method is a static version of Closure::bindTo(). See the documentation of that method for more information.
closure
The anonymous functions to bind.
newthis
The object to which the given anonymous function should be bound, or
NULL for the closure to be unbound.
newscope
The class scope to which associate the closure is to be associated, or 'static' to keep the current one. If an object is given, the type of the object will be used instead. This determines the visibility of protected and private methods of the bound object.
Returns a new Closure object or FALSE on failure
Example #1 Closure::bind() example
<?php
class A {
private static $sfoo = 1;
private $ifoo = 2;
}
$cl1 = static function() {
return A::$sfoo;
};
$cl2 = function() {
return $this->ifoo;
};
$bcl1 = Closure::bind($cl1, null, 'A');
$bcl2 = Closure::bind($cl2, new A(), 'A');
echo $bcl1(), "\n";
echo $bcl2(), "\n";
?>
The above example will output something similar to:
