if $x is not defined you will get a warning but that depends on error settings in 
php.ini.
This construction checks whether $x is defined or $x is true.

$x must be defined.

[PHP] variable test

Hi,

I'm asking me, what is the difference of the two "ifs".

if($x)
   echo $x;

if(!empty($x))
   echo $x;
