PHP proxy
This library provides proxy classes with easily extendable behavior. Library includes ready for use caching proxy and lazy instantiation proxy., (*1)
Requirements and dependencies
This library has no external dependencies, if installed with --no-dev option. Caching behavior memcache backend requires php memcache module to be enabled., (*2)
Installation
php composer.phar require mz/php-proxy
Basic usage
In-memory cache proxy
use MZ\Proxy\Shortcuts;
// object proxy
$object = new MyComplexClass();
$proxy = Shortcuts\wrapWithMemoryProxy($object, 5); // 5 seconds timeout (default = 0 - infinite)
$proxy->foo(); // executes foo, stores result in cache
$proxy->foo(); // returns cached result, real foo method is not executed
$proxy->bar(); // works here too
$property = $proxy->my_property // exactly as $object->my_property
$proxy->my_property = 123; // exactly as $object->my_property = 123
// set cached methods
$proxy->proxySetMethods(array('foo', 'bar'));
$proxy->foo(); // cached
$proxy->bar(); // cached
$proxy->baz(); // not cached
$proxy->proxySetMethods(null); // all methods cached fro this point (default)
$callable = function() {
// some time intensive code...
};
$proxy = Shortcuts\wrapWithMemoryProxy($callable);
$result = $proxy(); // executes function
$result = $proxy(); // returns cached result
Cache proxy with memcache
use MZ\Proxy\Shortcuts;
$object = new MyComplexClass();
$memcache = new \Memcache();
$memcache->addServer('localhost', 11211);
$proxy = Shortcuts\wrapWithMemcacheProxy(
$object,
'memcache_prefix',
$memcache
);
$result = $proxy->foo(); // executes foo
$result = $proxy->foo(); // returns cached result, real foo method is not executed
