Device Detection Considerations: Don’t redirect to homepage Offer ‘classic’ option Don’t make assumptions on screen size Wednesday, November 3, 2010 21

Zend Framework Example Take advantage of ZF’s powerful MVC set up View scripts determine layout of actions Layout script wraps everything into main layout Use Bootstrapper to detect device and setup MVC Wednesday, November 3, 2010 22

PHP’s role in native apps iPhone Android Blackberry App App App API Wednesday, November 3, 2010 39

Optimize APIs for mobile Content optimization Scalability Longevity Security Client/Server considerations Wednesday, November 3, 2010 40

Content Optimization Consider CPU and memory constraints Prefer JSON over XML Compress data Keep responses small But not too small (connection / routing overhead) Wednesday, November 3, 2010 41

Scalability AppStore featured/top listings Slashdot effect Consider the 80/20 rule of app popularity though Wednesday, November 3, 2010 42

Longevity Apps have different deployment patterns No ‘quick ﬁx’ in the application as in web apps Client/Server asynchronous updates Backwards compatibility Versioned API URLs: http://iportfolio.api.egeniq.com/portfolios/1.0/mvb/collections.json Wednesday, November 3, 2010 43

Longevity How long do you support your APIs? Can’t force people to delete their Apps Provide clean fallback Synchronized instead of real-time data Implement status check API calls Wednesday, November 3, 2010 44

API Security TLS/SSL Basic Auth OAuth? XAuth! PKI / TLSAuth Signed URLs: ?x=1&y=2 &signature=hash(secret, time limit, params) Wednesday, November 3, 2010 45

Client/Server considerations Image Processing in the API, instead of App Use Imagick / GD etc. Trade-off between bandwidth and processing power Apps support threading / asynchronisity Fire-and-forget API design Prepare/getResult call duos Push features into PHP APIs for reuse Wednesday, November 3, 2010 46

PHP’s role in native apps PHP has native support for: Web services JSON Compression Image manipulation Egeniq’s number 1 choice for App APIs 25-30% of App development time = API Wednesday, November 3, 2010 47
