https://wiki.php.net/rfc/internal_method_return_types

PHP 8.0 added return type for abstract methods on Iterator, ArrayAccess, Countable, IteratorAggregate
PHP 8.1 made non implementation as a Deprecated Warning
PHP 9.0 (no release date at this moment) will drop the support.

Temporary Fix : adding this Attribute
Will drop the Deprecated warning.

Adding return type will break compatibility before PHP 7.4,
Return type has been added on PHP 7.0, but "mixed" special type is required, and it has been added on PHP 7.4.
In order to be compatible with future PHP 9.0, once it will be release, we will have to drop the support to PHP Version before 7.4

Currently a lot of Unix distribution in LTS are running a PHP Version older than 7.4 so moving to the final solution of "add return type" should break a lot of setup for the moment.

https://wiki.php.net/rfc/phase_out_serializable

PHP 7.4 add a new Serialize mecanism
PHP 8.1 made old method, "Serializable implementation" deprecated
PHP 9.0 (no release date at this moment) will drop the support.

Temporary Fix: Adding both method serialize/unserialize and __serialize/__unserialize

In order to be compatible with future PHP 9.0, once it will be release, we will have to drop the support to PHP Version before 7.4.

Currently a lot of Unix distribution in LTS are running a PHP Version older than 7.4 so moving to the final solution of "add return type" should break a lot of setup for the moment.

Each class has been serialized/unserialized and compared on PHP 8.1.2 and 5.6.30

…parameters

Mainly ensure use of string instead of null / false by casting the variable into (string)
Also fix method/function arguments with default value must be at the end.

2 possible workaround, use partial implementation with php date method or use IntlDateFormatter.
As symfony1 is not intended to evolve, it should not rely on currently unused PHP-Extension (nor update composer.json).

I propose a fix to replace "strftime" by "date", with a translation of format for PHP 8.1+

It will lose the ability of translating date of logs (does anybody use it ?) and it will deprecated a few strftime format (probably not used)
Performances should remains OK

I only tested it with a few formats (the default one and a few others)
If you need some missing strftime formats, please add them.

sfException> fileExcerpt file can be null, and PHP 8.1 do not allow null on is_readable()

sfBrowser> Move sf_test conf before getContext, because getContext can throw some sfException, which will raise some printStackTrace, hidden by another Exception "header already sent ..."

lime.php> some trace can have no "file" (internal methods call)
lime.php> handle_exception can handle Error/Throwable, not avaialble under php7.2: remove typing

sfTestFunctionalBase> can throw exception

Fix Select Unit test NewActivePendingExpired.
DomDocument on recent php return a list of values, not concatened ones.

Fix SessionStorage UnitTest.

sfSessionStorage could not be restarted.
Flag $sessionStarted as false when shutdown to avoid error during unit test which can start several sfSessionStorage

Storage need to be shutdown to avoid:
PHP Warning:  session_name(): Session name cannot be changed when a session is active

ValueError: fread(): Argument #2 ($length) must be greater than 0

TypeError: count(): Argument #1 ($value) must be of type Countable|array Foo Given
Use Symfony Polyfill symfony/polyfill@d330c00

TypeError: count(): Argument #1 ($value) must be of type Countable|array, string given
Do not use Symfony pollyfill, is_array is enought

… null, $accept = false) must be compatible with sfPearRest::downloadHttp($url, $lastmodified = null, $accept = false, $channel = false)

8.0.0 	hour is no longer optional.
8.0.0 	minute, second, month, day and year are nullable now.

Numeric strings ending with whitespace ("42 ") will now return true. Previously, false was return instead.

Use same fix has main maintened Yaml lib :
symfony/yaml@4152e36
+ performance improvement
symfony/yaml@2b5f2ae

When $previousIndent was equal to 0, and $matches['indent'] = "    "

PHP(before 8.0)> (0 != "    ") ==> false
PHP8.0+ > (0 != "     ")  ==> true

In order to keep "false" value we avoid "0" as a valid value.

- Using negative TTLs to force the immediate expiration of keys, while
  convenient in tests, doesn't work consistently with APC and is an
  undocumented feature. Using a low TTL and sleep() is what guarantees
  that it works for APC. See krakjoe/apcu#184

- The setting apc.use_request_time interferes with key expiration when
  running on the CLI. Making sure it always has a sensible value for
  running the tests. See krakjoe/apcu#392

Support for the APCu extension (through sfAPCuCache) as an alternative
to APC, which no longer works with recent versions of PHP.

From PHP 7.2 onward, session functions are stricter and may not work
if output/headers have already been sent out. Using output buffering
prevents this issue.

Replace the use of sfAPCCache with sfFileCache in
sfCacheSessionStorageTest so that it doesn't depend on APC being
available.

Avoid error:

Step to reproduce :
$form = new sfForm();
$form->updateValues(array('foo' => 'value'));

PHP 5.3 coding style

May use sfForm::getValues(), but as sfForm::updateValues() is a hack, it could be used before bind ($this->isBound = true);
