Description

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

Parameters

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.

Return Values

If setting, returns old flags, else returns flags

Errors/Exceptions

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.

Changelog

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.

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)
