[V8˖] Migrating your code to the V9

Because the V9 is relatively not backward compatible with the V8, here's a guide to help you to migrate your code:

⚠️ Minimum php version increased to 8.0+

As of the V9 the mandatory minimum php version has been increased to 8.0+. Once released, the php version 8.1 will be unit-tested

Embedded autoload has been removed (and therefore, embedded dependencies)

Use Composer to include Phpfastcache in your project

Removed magics methods from CacheManager CacheManager::DriverName()

Use CacheManager::getInstance('DriverName') instead.
This decision was made to make the cache manager more consistent by removing the "old legacy code".

Updated ConfigurationOption which is no longer an ArrayObject class

You can no longer use the following array-compatible syntax: $config['yourKey'] = 'value'
Use the object-notation syntax instead: $config->setYourKey('value')

However, this syntax is STILL valid through the configuration constructor
For the default config object: new ConfigurationOption(['yourKey' => 'yourValue'])
Or for specific config objects: new \Phpfastcache\Drivers\Files\Config(['yourKey' => 'yourValue'])
Finally, the config name you try to set MUST be recognized or an exception will be thrown.

Deprecated \Phpfastcache\Helper\CacheConditionalHelper

Use \Phpfastcache\CacheContract instead. See Wiki.

Removed Couchbase driver (SDK 2 support dropped)

It is now replaced by Couchbasev3 driver (SDK 3), the configuration options are all the same plus scopeName and collectionName that are now configurable.

Updated EventManager instances

• Updated argument type #2 ($items) of onCacheSaveMultipleItems() event from ExtendedCacheItemInterface[] to EventReferenceParameter($items)
• Updated argument type #2 ($items) of onCacheCommitItem() event from ExtendedCacheItemInterface[] to EventReferenceParameter($items)
• Updated argument type #2 ($value) of onCacheItemSet() event from mixed to EventReferenceParameter(mixed $value)

See EVENTS.md file for more information

Upgraded Phpfastcache API

• The Phpfastcache API has been upgraded to 4.0.0 with BC breaks. See full changes
• Renamed Api::getPhpFastCacheVersion() to Api::getPhpfastcacheVersion()
• Renamed Api::getPhpFastCacheChangelog() to Api::getPhpfastcacheChangelog()
• Renamed Api::getPhpFastCacheGitHeadHash() to Api::getPhpfastcacheGitHeadHash()

Removed Devtrue and Devfalse drivers

They have not been replaced. However, the Devrandom driver with configurable factor chance and data length has been added

Removed configuration entry htaccess for files-based drivers.

• We consider that it's no longer the task of Phpfastcache to handle server configuration
• Removed IOConfigurationOptionTrait::getHtaccess()
• Removed IOConfigurationOptionTrait::setHtaccess()

Configuration object will now be locked once the cache pool instance is running

If you try to set a configuration value after the cache pool instance is being built, an exception will be thrown.

Removed Cookie driver because of its potential dangerosity

However, you can always implement it by yourself if you want to by putting it back from previous versions using \Phpfastcache\CacheManager::addCustomDriver() method
