Re: [PHP] test variable value?

[M. Sokolewicz]

remember though that
if(!$x) {
  echo 'nothing here';
}

will also output 'nothing here' when provided with the string '0'!

I do use if(!$var) for simple application. Only _IF_ I need to know if the
$var is defined but empty or so I would use especific functions.

How about...

if (!$x){
  echo "x is empty";

Because $x could be an empty string, 0, false, null or undefined. If
that's what you need to check for then knock yourself out.
