I was wondering if

PHP Code:

if 


can involve non numerical stuff like is this possible? I've been trying to get it to work but had no luck so maybe there is another way of doing it that I don't know of...

PHP Code:

$a = x;
$b = y;
if ($a = $b){
$c = 0;
} else {
$c = 1;
} 


thanks

Of course it's possible.
Your problem is surely that you don't do a test in your if, but an assignation.

Remember:
1 = means an assigantion

PHP Code:

$x=4;
$y=true; 


2 = means a comparison, with casting between different types

PHP Code:

1==3  //return false
1=='1'  //return true
'a'=='A'  /return false
4!=true //return true 


3 = mean a comparison, but without type casting

PHP Code:

1==='1'  //false
'a'==='a' //true
1!=='1'  //true 


So, in your test, try to put 2 = in your if statements

PHP Code:

if ($a == $b){
  $c = 0;
} else {
  $c = 1;
}

Thanks! It worked like a charm!

An if statement simply checks weather a condition is true, as in

PHP Code:

if(condition) {...} 


What ever 'condition' might be (given there are no errors) - a comparison, an assignment, a function call etc. - if simply checks weather it returns true, and if so executes the code within brackets.
