Confusing with a php variable issue

Question

In the below code, after the preg_match, $videoinfo['video']['rendering'] most definitely equals "Progressive".

So, I am expecting the final echo to output "Rendering: Progressive Scan".

However, it doesn't. It outputs "Rendering: Progressive" Am I missing something obvious here?

Thanks for your help!

if(preg_match("/^Video Field Order\s+:(.*)$/im",$output,$matches)){
    $videoinfo['video']['rendering'] = $matches[1];
    if($videoinfo['video']['rendering'] == "Progressive"){              
        $videoinfo['video']['rendering'] = 'Progressive Scan';                      
    }               
    echo("Rendering: " . $videoinfo['video']['rendering']);
}

Are you sure there isn't any trailing spaces in that string? Try trim($matches[1]); — h2ooooooo

That means the condition is not true, which means the string is not actually "Progressive". Likely some additional trailing whitespace or so. — deceze

Yes! There are trailing spaces. I knew there was a simple answer here somewhere. Thanks for helping me track that down!! — CRAIG

You do this

echo("Rendering: " . $videoinfo['video']['rendering']);

and you say that It outputs "Rendering: Progressive."

That means that $videoinfo['video']['rendering'] contains the string Progressive.. Mind the dot!

So it has 1 character extra (the dot), and that's why your equals doesn't work.

Good catch. There should not have been that dot there. Sorry for that confusion. Editing.
