Also im moment bin ich dabei eine Suchmaschine für meine Homepage zu machen, und ich will den Titel einer gefundenen Datei ausgeben, wie schaff ich das?
z.B.
<br />
Netkoma<br />
...
wie kann ich den Text, der zwischen steht herrausfinden?<br />

ich finde dort kein Beispiel!?<br />
Ich hab zwar schon eins gefunden nur es klappt nicht:<br />
<table align="center" border="0" cellspacing="1" cellpadding="4" bgcolor="#FFFFFF" width="92%" class="quote"><tr><td>the following 2 functions grab a piece of content from an external html and lists that in separate places -- i.e. the title for html documents, or a list of subtopics dynamically.. the first function grabs the first found and returns a string, the second recursively searches the rest of the document and returns an array..<br />
I found this was very useful to display articles on my website that had various topics marked by a consistent <P class=subtopic>, and the end </ P> tags..<br />
<br />
<?php<br />
function stripfromtext($haystack, $bfstarttext, $endsection) {<br />
$startpostext = $bfstarttext;<br />
$startposlen = strlen($startpostext);<br />
$startpos = strpos($haystack, $startpostext);<br />
$endpostext = $endsection;<br />
$endposlen = strlen($endpostext);<br />
$endpos = strpos($haystack, $endpostext, $startpos);<br />
return substr($haystack, $startpos + $startposlen, $endpos - ($startpos + $startposlen));<br />
}<br />
<br />
function &stripfromtextarray($haystack, $bfstarttext, $endsection, $myarray=array(), $offset=0) {<br />
$startpostext = $bfstarttext;<br />
$startposlen = strlen($startpostext);<br />
$startpos = strpos($haystack, $startpostext, $offset);<br />
$endpostext = $endsection;<br />
$endposlen = strlen($endpostext);<br />
$endpos = strpos($haystack, $endpostext, $startpos);<br />
$myarray[] = substr($haystack, $startpos + $startposlen, $endpos - ($startpos + $startposlen));<br />
$offset = $endpos;<br />
if (is_numeric(strpos($haystack, $startpostext, $offset))) {<br />
return stripfromtextarray($haystack,$startpostext, $endpostext, &$myarray, $offset);<br />
}<br />
else {<br />
return $myarray;<br />
}<br />
}<br />
?><br />
<br />
The following is an example of the use of these functions<br />
<?php<br />
$filetitle = stripfromtext ($content, "<P CLASS=title>", "</ P>");<br />
<br />
// and<br />
$rightmenuarray = stripfromtextarray($content, "<P CLASS=subtitle>", "</ P>");<br />
<br />
foreach ($rightmenuarray as $rm) {$rightmenu.=$rm."<br>";}<br />
