Wenn die Checkboxen alle denselben Namen haben, überschreibt die zweite die erste etc. Aber in PHP gibts dafür ja Arrays. Und man glaubt es kaum, man kann den Namen der Checkbox als Array definieren:

<input type="checkbox" name="types[]" value="html"> html<br>
<input type="checkbox" name="types[]" value="php"> php<br>
<input type="checkbox" name="types[]" value="jpg"> jpg<br>

und dann ist:

$a_types = ($_REQUEST["types"]);

     $string2 =
     ereg_replace('<font size=.+4.>+ ?<b class=.bltxt.>(.*)</b> ?</font>'
     ,'<h1>\1</h1>',$string);

• ersetze alle Pfade, die mit ../../gallery/ oder ../gallery beginnen und danach irgendwas haben durch – na egal (diesmal mit preg-replace), hier ist der Suchstring:

     /(\.\.\/)+?gallery\/.+?"/

Mache eine Sicherheitskopie von allen html files in einem Verzeichnis, natürlich mit Unterverzeichnissen, aber nimm nicht den ganzen anderen Müll mit… vielleicht geht es ja auch schneller, aber das funzt:

find . -name '*.html' | pax -wdx ustar | gzip > Htmlfiles.tgz

Finde HTML und PHP:

find . -name '*.html' -o -name '*.php'

Count files

find . -name '*.html' -o -name '*.php' | wc -l

find . -type f | wc -l

Only list the directories in the current directory.

ls -d */

Find Members of a group?? in php it’s quite simple…

$file["group"]["members"]

in unix?? maybe something like

more /etc/group | grep groupname

  function cleanString($filename) {
    return ereg_replace("[^-[:alnum:].+]","",$filename);
  }

oder, um auch z.B. chinesische Zeichen zu verbieten…

function cleanString($wild) {
   $filename = ereg_replace("[^-[a-zA-Z0-9].+]","",$wild);
    return $filename;
}

 $list_ignore = array
         ('.','..','images','Thumbs.db','index.php','.htaccess','.htpasswd');
 $handle=opendir ('.');
 while (false !== ($file = readdir ($handle))) {
   if (!in_array($file,$list_ignore)) $out[filemtime($file)] =
       $file."</td><td>".date("d.m.Y",filemtime($file));
 }
 closedir($handle);
 if ($out)
 {
  krsort ($out);
  echo "<table border=0>";
  foreach($out as $item) {
	echo "<tr><td><a href=\"$item\">$item</a></td></tr> \n";
  }
 }

A function that finally gives me the complete path to a menu item. Not just the path to the parent as getPath… here we go:

 # builds total path (including the item itself...)
 # call $m->buildTotalPath($m->menu, array())
 # use $m->pathtohere

 function buildTotalPath($menu, $path, $level=0) {
    // loop through the (sub)menu
    foreach ($menu as $node_id => $node) {
        // save the path of the current node in the urlmap
	##!!! include current node
	$path[$level] = $node_id;
	$this->pathtohere[$node["url"]] = $path;
        // if current node has a submenu
        if ($node["sub"]) {
           // continue search recursivly -
	   $this->buildTotalPath($node["sub"], $path, $level+1);
        }
    }
    return true;
 } 

 # get path including item itself.....
 function getTotalPath() {
    $this->buildTotalPath($this->menu, array());
    $this->current_url = $this->getCurrentURL();
    while ($this->current_url &&
           !isset($this->pathtohere[$this->current_url]) &&
           !isset($this->pathtohere[$this->current_url.".html"])) {
	$this->current_url = substr($this->current_url, 0, -1);
    }
    if (isset($this->pathtohere[$this->current_url])) {
       $myvar = $this->current_url;
    } else {
       $myvar = $this->current_url.".html";
    }
    return $this->pathtohere[$myvar];
 }

thanks to Ulf for providing the idea and the source code of the menu functions!
