(PECL uopz 2 >= 2.0.2, PECL uopz 5, PECL uopz 6)
uopz_flags — Get or set flags on function or class
uopz_flags ( string $function [, int $flags = PHP_INT_MAX ] ) : int
uopz_flags ( string $class , string $function [, int $flags = PHP_INT_MAX ] ) : int
Get or set the flags on a class or function entry at runtime
class
The name of a class
function
The name of the function. If class is given and an empty string is passed as function, 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
As of PHP 7.4.0, if the parameter flags is passed, uopz_flags() throws a RuntimeException, if OPcache is enabled, and the class entry of class or the function entry of function is immutable.
| Version | Description |
|---|---|
| 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. |
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)
Example #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());
?> The above example will output:
bool(false)
