Description
The following code:
compile-test.php
<?php
var_dump(opcache_compile_file(__DIR__ . '/releases/v1/functions.php'));
// expecting `bool(false)` since opcache_compile_file() shouldn't have executed the compiled file.
var_dump(in_array('foo', get_defined_functions()['user']));
// expecting successful compilation: `bool(true)`
var_dump(opcache_compile_file(__DIR__ . '/releases/v2/functions.php'));releases/v1/functions.php
<?php
function foo(): string {
return 'foo_v1';
}releases/v2/functions.php
<?php
function foo(): string {
return 'foo_v2';
}Resulted in this output:
bool(true)
bool(true)
PHP Fatal error: Cannot redeclare foo() (previously declared in /private/tmp/opcache/releases/v1/functions.php:4) in /private/tmp/opcache/releases/v2/functions.php on line 4

Warning: Zend OPcache could not compile file /private/tmp/opcache/releases/v2/functions.php in /private/tmp/opcache/compile-test.php on line 4
bool(false)
But I expected this output instead:
bool(true)
bool(false)
bool(true)
Additional Context:
The issue happens on both cli and php-fpm. It seems to be similar to https://bugs.php.net/bug.php?id=66066 . While the use case in bug 66066 might be less common in the real world and probably should be avoided, it's a perfectly valid use case to run multiple releases with similar files under the same php-fpm instance.
Workaround
Our current workaround is to compile different releases with different requests, i.e. PHP will happily process the following logics in two different requests.
compile-v1.php
<?php
var_dump(opcache_compile_file(__DIR__ . '/releases/v1/functions.php'));compile-v2.php
<?php
var_dump(opcache_compile_file(__DIR__ . '/releases/v2/functions.php'));opcache_get_status()['scripts'] shows that the two files have been compiled successfully.
