hide sting if variable is null

[demo7up]

I need help making something like this.

 

 

so for example

if ($number == NULL) {
echo 'there is a $number';
}
else {
echo 'There is no value';
}

 

thanks in advance

And the problem is??? Besides the fact that you have a variable inside single quotes?

i totally just came up with that in my head had no idea it was correct.. besides the single quotes..

 

also would this be better?

 

 

 

if (isset($number))
{
   echo "Variable is set";
}  
else
{
echo "its not set";
}

I usually use isset personally, I don't know that one version is better than the other.

 

If you "come up" with code, rather than asking other people if it's usable you could, you know, try to use it?

isset() is to check if the variable has been set, regardless of its value,

the first post will tell you if the variable has a value of null.
