Bug #77797 Array assignment
Submitted: 2019-03-26 12:27 UTC Modified: 2019-03-26 12:35 UTC

Status: Duplicate Package: Unknown/Other Function
PHP Version: 7.2.16 OS: linux
Private report: No CVE-ID: None

When passing an array append assignment directly to a public or protected method with opcache enabled, the array itself is passed to the method instead of the assigned value. Calling private methods or functions will not trigger this behaviour.

This behaviour only occurs with opcache enabled (tested both in cli and as apache module), so you'll need to run it at least twice to see the faulty behaviour.

Test script:
class Foo
    public function baz($arg)
        return $arg;

    public function bar()
        $a = [];
        return $this->baz($a[] = 'foo');

$foo = new Foo();

Expected result:
string(3) "foo"

Actual result:
array(1) {
  [0] =>
  string(3) "foo"
