PHP Bug Type: Documentation problem
Bug description: is_callable needs documentation
Please add a description of is_callable to the documentation. Here are
some rough notes about how what this function does.
This function wraps zend_is_callable. The first argument is the name of a
function or method. Class an object methods are specified by passing an
array with two elements: class or object and method name.
The second argument seems to be for checking syntax only, but I can't
figure out how to make is_callable return FALSE when the second argument
is TRUE.
The third argument receives the "callable name". In the example below
it's "a::b". Note, however, that despite the implication that a::b() is a
callable static method, this is not the case.
<?
class a
{
var $c;
function b()
{
return($this->c);
}
}
$d = new a;
if(is_callable(array($d, 'b'), FALSE, $name))
{
print($name);
}
?>
