c++ extension in php yii framework -


i want use c++ extension in yii. have compile .so file , used in php script. when used in yii framework, occurs "class not found",anyone knows why?

the c++ extension rdkafka.so : https://github.com/arnaud-lb/php-rdkafka

 $conf = new rdkafka\conf();  $conf->set("ssl.key.location","./conf/client.key");  $conf->set("ssl.certificate.location","./conf/client.pem");  $conf->set("ssl.ca.location","./conf/ca.pem");  $conf->set("security.protocol","ssl");

if running code in namespaced file, need either import class, or prefix \:

$conf = new \rdkafka\conf();

'hasOwnProperty' in javascript -

i use obj.hasownproperty judge whether object has property, when replaced obj[prop] !== undefined , not normal implementation, ask, why behind method can not use it? object.hasownproperty(prop); object[prop] !== undefined; obj[prop] !== undefined wrong 2 reasons: you can explicitly set property undefined , obj[prop] = undefined; . obj.hasownproperty(prop) return true in case. obj[prop] follow prototype chain, return property that's inherited. obj.hasownproperty(prop) returns true if property exists directly in object, returns false inherited properties.
