uopz_flagsGet or set flags on function or class

说明

int uopz_flags ( string $class , string $function , int $flags )

Get or set the flags on a class or function entry at runtime

参数

class

The name of a class

function

The name of the function

flags

A valid set of ZEND_ACC_ flags, ZEND_ACC_FETCH to read flags

返回值

If setting, returns old flags, else returns flags

范例

Example #1 uopz_flags() example

<?php
class Test {
    public function 
method() {
        return 
__CLASS__;
    }
}

$flags uopz_flags("Test""method"ZEND_ACC_FETCH);

var_dump((bool) (uopz_flags("Test""method"ZEND_ACC_FETCH) & ZEND_ACC_PRIVATE));
var_dump((bool) (uopz_flags("Test""method"ZEND_ACC_FETCH) & 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_FETCH) & ZEND_ACC_PRIVATE));
var_dump((bool) (uopz_flags("Test""method"ZEND_ACC_FETCH) & ZEND_ACC_STATIC));
?>

以上例程的输出类似于:

bool(false)
bool(false)
int(1234567890)
bool(true)
bool(true)

If the method name is set to an empty string, then the flags for the CLASS itself will be affected, instead of an individual method. This can be used to remove the "final" attribute from a class.
<?php
declare(strict_types=1);

final class
MyClass { function mymethod() {} };
uopz_flags(MyClass::class, '', 0);
?>

Note: Although not documented, setting the method to NULL will also target the CLASS flags, however, that syntax will clash with strict types because of the developer's improper function signature.
