How to avoid MissingPropertyException

Question

If an object does not have a property and I am accessing the property, we get a MissingPropertyException. Can I do something similar to safe null (?.

You can also use try/catch

try
{   env.GERRIT_TOPIC=GERRIT_TOPIC
}
catch (e_val)
{   echo 'missing GERRIT_TOPIC'
}
