<p>Sure your code will run, but while Volley is running in a separate thread, you've gone ahead to <code>return mJsonWeather[0];</code>, which is null. </p>

List all installed programs on windows using PHP <p>How can I list all installed programs in windows using php or how can I search for a installed program in windows using php?</p>
