classkit_method_add — Dynamically adds a new method to a given class
$classname
, string $methodname
, string $args
, string $code
[, int $flags = CLASSKIT_ACC_PUBLIC
] ) : bool此函数是实验性的。此函数的表象，包括名称及其相关文档都可能在未来的 PHP 发布版本中未通知就被修改。使用本函数风险自担 。
classnameThe class to which this method will be added
methodnameThe name of the method to add
argsComma-delimited list of arguments for the newly-created method
code
The code to be evaluated when methodname
is called
flags
The type of method to create, can be
CLASSKIT_ACC_PUBLIC,
CLASSKIT_ACC_PROTECTED or
CLASSKIT_ACC_PRIVATE
Note:
This parameter is only used as of PHP 5, because, prior to this, all methods were public.
成功时返回 TRUE， 或者在失败时返回 FALSE。
Example #1 classkit_method_add() example
<?php
class Example {
function foo() {
echo "foo!\n";
}
}
// create an Example object
$e = new Example();
// Add a new public method
classkit_method_add(
'Example',
'add',
'$num1, $num2',
'return $num1 + $num2;',
CLASSKIT_ACC_PUBLIC
);
// add 12 + 4
echo $e->add(12, 4);
?>
以上例程会输出：
16
If you creates methods by using classkit_method_add(), they are not visible in get_class_methods().
class A
{
public function foo()
{
return "foo!\n";
}
}
classkit_method_redefine('A','bar','','return "bar !\n";',CLASSKIT_ACC_PUBLIC);
print_r(get_class_methods('A'));
// writes only "foo"
