PHP on Android
● Android “is” Linux.● So it should work.
– Of course it does..● ARM cross compiling.● Method 1 (easy):
– Static compilation gnu libc (> 7MB)
PHP for Android: scripting PHP en Android
PHP en Android
● Not so easy way:– Linked to Bionic.
● Bionic: libc de Android– BSD.– sizeof(gnu_libc) * 0.5– Missing stuff.
● PHP on Android.– Php-cli sapi– Agcc – Tweaks because of bionic.– =~ 2MB– Sockets, json.

The problem
● API php → OK● UI? (php-gtk?)● Calls?● Messages?● Location?● Sensors?● ...
● Mobile web.
PHP for Android: scripting PHP en Android
The solution
● Google project (Damon Kohler), opensource.● SL4A (Scripting Layer For Android) ● Android app (APK).● Layer for scripting languages.● Exposes Android API.● Really active, often releases.
PHP for Android: scripting PHP en Android
The solution
● Officially supported languages:– Python.– Perl.– Ruby.– Lua...
● Foreach interpreter → APK installer.● PHP? → issue #40 → phpforandroid.net

● APKs:– SL4A– PFA
● SL4A detects PFA(intent filter).

The Android class
<?phpinclude 'Android.php';$droid = new Android();
public function __call($name, $args) { return $this->rpc($name, $args);}
Json RPC
PHP for Android: scripting PHP en Android
The Android class
public function rpc($method, $args) { $data = array( 'id'=>$this->_id, 'method'=>$method, 'params'=>$args ); $request = json_encode($data) . “\n”; $sent = socket_write($this->_socket, $request, strlen($request));
PHP for Android: scripting PHP en Android
The Android class
$response = socket_read($this->_socket, 1024, PHP_NORMAL_READ) or die("Could not read input\n"); $this->_id++; $result = json_decode($response);
return array ('id' => $result->id, 'result' => $result->result, 'error' => $result->error ); }
