Dont know very much about PHP this shoule be a straightforward one for anyone familiar with it. Below I am trying to figure out what this line does so I can replicate it in Java.<br />
<br />
if (!$power) $power=0;<br />
<br />
I think it is saying, If power is null then power is 0.<br />
<br />
Can anyone confirm?

What does this PHP sentence mean/do?

PHP is a widely-used server-side scripting language especially suited for web development, powering tens of millions of sites from Facebook to personal WordPress blogs. PHP is often paired with the MySQL relational database, but includes support for most other mainstream databases. By utilizing different Server APIs, PHP can work on many different web servers as a server-side scripting language.
