Stop string returning false

[s1yman]

Hi all,

 

I've got a code that searches a string (an embed script) and strips it down to the youtube video link.

 

		$encoded = strchr("$encoded","http://www.you");
	$encoded = strrev($encoded);
	$encoded = strrchr("$encoded","&");
	$encoded = strrev($encoded);
	$encoded = str_replace("-nocookie","","$encoded");
                $encoded = str_replace("&","",$encoded);

 

Might be a bit "busy" .. but I'm a rookie, still that works well enough.

 

My problem is that it searches for http://www.you - but if it is not a youtube video it will returns blank (obviously).

So my question is, how do I go about stopping it from making my string nothing when it's not a youtube vid?

 

I have tried to play around with if statements, but I'm bit clueless .. any help really appreciated!! 

 

Thanks in anticipation

thats just strings bro

 

there is no conditional operators to return different conditions so you gotta learn some programming basics

 

strchr("$encoded","http://www.you");

 

to

 

$encoded = strchr($encoded,"http://www.you") == '' ? $encoded : strchr($encoded,"http://www.you");

 

 

but it's confusing me why you just use you.. and not just youtube i can go to youporn.com and it will work

"learning" is always problem if you don't follow structured courses ...

That works .. thanks!

the reason for the critera was I need the full url .. and as it's searching the embed link, I couldn't put "http" because that would pull the play url .. maybe i wanted it to cover youporn as well lol

 

cheers for your help bro ..

$url = 'http://www.youtube.com/vid?id=bla';
$urlParts = parse_url($url);

if ($urlParts['host'] === 'www.youtube.com' || $urlParts['host'] === 'youtube.com') {
  //youtube
  $params = array();
  parse_str($urlParts['query'], $params);
  echo $params['id'];//bla
}
