Was muss Deine Tag Claus können?

select alter, count(alter) as font-size from tabelle group by alter

$q = query();
$m = fetch();
while ($row = fetchrow())
{
  echo "<span style='font-size:".max(8, min(24, $row->font-size))."'>{$row->alter}</span>";
}

select alter, count(alter) as font-size, min(alter) AS min, max(alter) AS max from tabelle group by alter

$q = query();
$m = fetch();
while ($row = fetchrow())
{
  $k =16/($row['max']-$row['min']);
  echo "<span style='font-size:".round($row->font-size*$k)."'>{$row->alter}</span>";
}

Irgendwie funktioniert deine Lösung nicht.

Wäre aber schon toll, wenn Du Deine funktionierende Variante auch posten würdest.

$abfrage = "SELECT interessen, interessen2, interessen3 FROM tabelle";
$result = mysql_query($abfrage);
while ($row = mysql_fetch_array ($result))
{
$data[] = $row['interessen']."\n".$row['interessen2']."\n".$row['interessen3'];
}

$data = implode('',$data);
 
// Woerter splitten
$words = preg_split("/\n/", $data);
$acv = array_count_values( $words );
 
// Nicht erwuenschte Woerter loeschen
$bannedwords = array('');
$i = 0;
foreach($acv as $k=>$v) {
if (!array_search(strtolower($k),$bannedwords) and eregi("[a-zA-Z]",$k) and $i<=40 and strlen($k)>2) {
 if (isset($new_acv[strtolower($k)] ))
 $new_acv[strtolower($k)] += $v;
 else
 $new_acv[strtolower($k)] = $v;
 $i++;
}
}
 
// Alphabetisch sortieren
ksort( $new_acv );

// Clouds erstellen
foreach( $new_acv as $k=>$v) {
$size = $v*1;
$weight = $v*4;
 
if ($size > 4) $size = 4;
if ($weight > 50) $weight = 50;

$kurl = urlencode("$k");
echo "<a href=\"suche.php?q=$kurl\" style=\"font-size: {$size}em; font-weight: {$weight}\">$k</a>&nbsp;&nbsp;\n";
}

Gibts das auch für Bilder?

$abfrage = "SELECT interessen, interessen2, interessen3 FROM tabelle";
$result = mysql_query($abfrage);
while ($row = mysql_fetch_array ($result))
{
$data[] = $row['interessen']."\n".$row['interessen2']."\n".$row['interessen3'];
}

$data = implode('',$data);

// Woerter splitten
$words = preg_split("/\n/", $data);
$acv = array_count_values( $words );

// Nicht erwuenschte Woerter loeschen
$bannedwords = array('');
$i = 0;
foreach($acv as $k=>$v) {
if (!array_search(strtolower($k),$bannedwords) and eregi("[a-zA-Z]",$k) and $i<=40 and strlen($k)>2) {
if (isset($new_acv[strtolower($k)] ))
$new_acv[strtolower($k)] += $v;
else
$new_acv[strtolower($k)] = $v;
$i++;
}
}

// Alphabetisch sortieren
ksort( $new_acv );

// Clouds erstellen
foreach( $new_acv as $k=>$v) {
$size = $v*1;
$weight = $v*4;
 
if ($size > 4) $size = 4;
if ($weight > 50) $weight = 50;

$kurl = urlencode("$k");
echo "<a href=\"suche.php?q=$kurl\" style=\"font-size: {$size}em; font-weight: {$weight}\">$k</a>&nbsp;&nbsp;\n";
}
