I doubt this is a valid expression for your ternary operator, also with this code the integer value
change for error_reporting occurs?
error_reporting(E_ALL);
class Foo
{
public $a;
public function seta($a) {
$b = @random_int(16, 16);
if(is_int($b))
$this->a = $b;
return $a;
}
public function numbera() {
return $this->a;
}
}
$c = new Foo();
$c->seta(0);
$var = $c->numbera();
if($var != 16)
echo 'bug' . PHP_EOL;
else
echo 'normal' . PHP_EOL;
var_dump($var, error_reporting(), @error_reporting());
The @ operator will no longer silence fatal errors (E_ERROR == 1, E_CORE_ERROR == 4, E_COMPILE_ERROR
== 64, E_USER_ERROR == 256, E_RECOVERABLE_ERROR == 4096, E_PARSE == 4)

I cannot reproduce this with PHP 8.0.13 with Apache 2.4 (mod_php)
on Windows.

Description:
------------
The value of error_reporting() function (and global error reporting setting) gets overridden when a
native PHP function such as random_int() or filemtime() gets called with a suppress "@"
operator and assigned to a class variable.
I am running PHP Version 8.0.13 with the latest Apache2. I was able to reproduce this also when ran
as FPM. I was not able to reproduce this when called as CLI. I am using a precompiled binaries from
https://launchpad.net/~ondrej/+archive/ubuntu/php/.
I was not able to reproduce this on PHP7.4 when install via Ubuntu repos. This might be only
relevant to the build from that repository (which is used by many people AFAIK).
Test script:
---------------
<?php
error_reporting(E_ALL);
class Foo
{
public $a;
public function bar() {
$this->a = (true) ? @random_int(0, 100) : false;
}
}
var_dump(error_reporting()); //int(32767) = E_ALL
$c = new Foo();
$c->bar();
var_dump(error_reporting()); //random int
Expected result:
----------------
int(32767)
int(32767)
Actual result:
--------------
int(32767)
int(5) //random int
