A small introduction into: - Zend\EventManager - Zend\Serializer - Zend\Cache - Zend\Stdlib\ErrorHandler

1. ZendEventManager
ZendSerializer
ZendCache
ZendStdlibErrorHandler

2. ZendEventManager
Simple subject/observer patterns
Aspect-Oriented designs
Event-driven architectures

3. ZendEventManager
Simple subject/observer patterns
Aspect-Oriented designs
Event-driven architectures
It does not mean it is asynchron

4. ZendEventManager
Attach (aggregate) listeners
Event name(s)
Callback
Priority

5. ZendEventManager
Trigger events
Event name
Target
Arguments / Parameters (optional)
Until callback (optional)

6. ZendEventManager
Target
EventManager
Listener 1 Listener 2 Listener N

7. ZendSerializer
generate storable representation of PHP types
PHP type → string
string → PHP type

8. ZendSerializer
generate storable representation of PHP types
PHP type → string
string → PHP type
Adapter based interface
Throws Exceptions on error

9. ZendSerializer
Adapters
serialize() / unserialize() (default)
igbinary_serialize() / igbinary_unserialize()
JSON
Action Message Format AMF0 / AMF3
XML using WDDX
Python's pickle module
Native PHP code

10. ZendCache
ZF1
Inflexible frontend / backend structure
Only permit strings
Requires serialization on frontend level
Different frontends are not usable together
Tons of uncontrolled options
Missing procedures for optimations

11. ZendCache
ZF2
Storage Adapters
Wrappers for real storage resources
Storage Plugins
Objects to add missing functionality or to influence
behavior of a storage adapter
Cache Patterns
Predifined patterns to solve known performance
bottlenecks

12. ZendCache
Storage Adapter
get / has / set / add / replace / touch / meta /
counting
Multiple interface
„Check And Set“ feature
Find / Clear
Support for namespaces
Method for optimizing
Capabilities
Capacity

13. ZendCache
Storage Capabilities
Describes how a storage adapter works
Static TTL
max. TTL / max. key length
Use request time
Describes which features it supports
Supported datatypes / metadata
Expired read
Iterable
tagging

14. ZendCache
Storage Plugins
Event based
Influence adapters control flow
Reusable

15. ZendCache
Cache Patterns
Predifined patterns to solve known performance
bottlenecks
Should be used only in the specific situations they
are designed to address

16. ZendCache
Available Cache Patterns:
Output Cache
Caching a part the the output
Capture Cache
Buffer a complete page and write it as regular file for
further requests
Callback / Object / Class Cache
Caching function / method calls

17. ZendCache
What next
Add missing adapters
Xcache / SQLite / DBA / MongoDB …
Add missing plugins
MasterFile
Plugins to transform cache keys & values
Add missing patterns
PageCache

18. ZendStdlibErrorHandler
error suppression operator issues
Error will be triggered anymore
Not save to catch error message with
error_get_last()
Not possible to catch more than one error
Doesn't play well together with PHPUnit
Possibly disabled
