Conditional Statement confusion PHP

Question

EDIT : Damn... It was all about Path to the file and somehow I didn't thought about restructuring :| thanks to @Machavity I found the problem.

What is wrong with this code ?

If $foo is set and file exist file_exist() result should be 1. else if $foo is set but file does not exist file_exist() result should be 2. else result should be 3.

But I am only getting result 2 for all the three conditions. There gotta be something wrong with the second part of the elseif.

if ( isset ( $foo )  && file_exists ( 'bar.php' ) )
{
    echo '1';
}
else if ( isset ( $foo )  &&  ( ! file_exists ( 'bar.php' )  ) )
{
    echo '2';
}
else
{
    echo '3';
}

and probably file 'bar.php' really not exists? :) or you need setup right path to this file... — Vladimir Gilevich

Normally I don't like wrapping but try restructuring like this. This way you have a better idea of what's failing

if(isset($foo)) {
    if(file_exists('bar.php')) {
        echo '1';
    } else {
        echo '2';
    }
} else {
    echo '3';
}

Maybe I'm missing something, but does the restructuring actually help / answer the question?

Machavity Over a year ago

Wrapping should make it more obvious where the problem is (which seems to be in the file_exists portion)

Probably should be a comment then, but given it's a bit big for a comment, fair doos. :)

Thanks a lot buddy, I found the problem, restructuring did help :)

@JonStirling no restructuring advice is not the answer to the question but an advice to lead to the answer and it did help me narrow down to the problem area, otherwise I wasted all my time thinking I was not using conditional statements correctly, whereas the problem lied somewhere else. I would encourage such advice, and yes having code in an answer is better then in a comment.
