参数

The name of a class
-
function -
The name of the function. If
classis given and an empty string is passed asfunction, uopz_flags() gets or sets the flags of the class entry. -
flags -
A valid set of ZEND_ACC_ flags. If omitted, uopz_flags() acts as getter.

If setting, returns old flags, else returns flags
错误／异常
As of PHP 7.4.0, if the parameter flags is passed,
uopz_flags() throws a RuntimeException,

and the class entry of class
or the function entry of function is immutable.
更新日志
| 版本 | 说明 |
|---|---|
| PECL uopz 5.0.0 |
The flags parameter is now optional. Formerly,
ZEND_ACC_FETCH had to be passed to use uopz_flags()
as getter.

范例
示例 #1 uopz_flags() example
<?php
class Test {
public function method() {
return __CLASS__;
}
}
$flags = uopz_flags("Test", "method");
var_dump((bool) (uopz_flags("Test", "method") & ZEND_ACC_PRIVATE));
var_dump((bool) (uopz_flags("Test", "method") & ZEND_ACC_STATIC));
var_dump(uopz_flags("Test", "method", $flags|ZEND_ACC_STATIC|ZEND_ACC_PRIVATE));
var_dump((bool) (uopz_flags("Test", "method") & ZEND_ACC_PRIVATE));
var_dump((bool) (uopz_flags("Test", "method") & ZEND_ACC_STATIC));
?>
以上例程会输出：
bool(false) bool(false) int(1234567890) bool(true) bool(true)
示例 #2 "Unfinalize" a Class
<?php
final class MyClass
{
}
$flags = uopz_flags(MyClass::class, '');
uopz_flags(MyClass::class, '', $flags & ~ZEND_ACC_FINAL);
var_dump((new ReflectionClass(MyClass::class))->isFinal());
?>
以上例程会输出：
bool(false)
