2 questions about trim/output break

RCB

hey there im fairly new to the wonderful world of php so please bare with me 🙂

i have a couple questions about an output break...

first, i wanna get my output to display if greater then X amount of chars in a marquee else display normal.. is this the best way to do it?

$num_char=strlen($output);

if ($num_char < 50) {

echo" blah";
}else{
echo"<marquee>blah</marquee>";
}

also

if i have an output with multiple results "each result being on a new line" what would the code be in order to get the results to scroll if there are more then 10 lines of output?

thanks for your help!

Well, depending upon the newline character(s), you could use [man]explode/man to create an array, one element per line. Then use [man]count/man to count the number of elements in the array, if it's 10 or more, scroll it.... otherwise just display it.

ive still been having some trouble get those functions above to work ... the code im using to get my output info is

  	
$listeners = $shoutcast->GetListeners();
		if (is_array($listeners)) {
			for ($i=0;$i<sizeof($listeners);$i++) {

        $ipadd = $listeners[$i]["hostname"];

echo" $ipadd";


                }

       }else{

echo"no one connected";

                 }

this code grabs user connected to my shoutcast radio server and displays the ip addresses for eash user connected

the output would like something like this

22.334.33.3324.123.1.3276.33.22.345

a bunch of ip addy's with no spaces . can anyone show me how i can use this with the count() function

thanks again

$listeners = $shoutcast->GetListeners();
if(is_array($listeners))
{
    if(sizeof($listeners) > 10)
        echo '<marquee>';

foreach($listeners as $listener)
    echo $listener['hostname'];

if(sizeof($listeners) > 10)
    echo '</marquee>';
}

[man]sizeof[/man] is an alternative to count. Both will give you the number of elements in an array.

okay that works okay but now i have a differnent problem before i used to be able to connect the ips from my radio server to users in my forum db to retrieve the members info for each user connected to the radio server now it only displays 1 member is there something else i need to add?

here is a rough copy of my code

		$listeners = $shoutcast->GetListeners();



             if(is_array($listeners))
{
    if(sizeof($listeners) > 10)
        echo '<marquee>';

foreach($listeners as $listener)


$ipadd = $listener["hostname"];

            $SDK->DB->allow_sub_select=1;

$result = $SDK->DB->query("
      SELECT *
      FROM ibf_sessions s
      LEFT JOIN ibf_members m ON (m.id=s.member_id)
      WHERE s.ip_address='$ipadd'

                ");


while ($r = $SDK->DB->fetch_row($result)) {


  $minfo = $SDK->get_advinfo($r[member_id]);

  if ($r[ip_address] == '$ipadd' && $r[member_name] == !' ')
       {

echo "$minfo[name]<br>";

}

 else
       {
echo "no one<br>";

       }


  }



 if(sizeof($listeners) > 10)
    echo '</marquee>';
}


	  else {
		echo "Noone listens right now..";
        }

any ideas?

single quoted strings aren't parsed by PHP, so any variable values you want in them won't be replaced.

if ($r[ip_address] == '$ipadd' && $r[member_name] == !' ')

So unless the ip_address key has a value of a string which is: $ipadd, then you won't get any names..

I don't see much else that is awry.
