Examples

Example #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));
?>

The above example will output:

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.
