Another simple question.

$thing = 10

if(thing>1) { blabla

BUT what do we do with normal text?

let's say $thing = 'i'm wathing you';

I usually use if($thing) { blabla

but if the $thing is just a empty space it will still {, but it shouldn't..

I mean is there anything else I can use for text and if the variable is just a blank space, it should not work?

So if $thing contains any characters other than whitespaces {...

 

Use trim() e.g.

if(trim($thing))

 

Perfect. Thank you!

 

I don't understand ?.?

 

I see that you have troubles with if statement. Dont mind there is one of the most simple commands in PHP. For your problem I think that !($thing) or isset() could help. Check Compare Alpha - Numeric Values With PHP and php.net for if statement here. Hope that helps
