Salve allora ho risolto con uno script trovato qui si html.it:
<?php
// set text file location here
$PATH = 'pg19141.txt';
// if no location is set, an input field will be used (for a url)
#$PATH = null;
$search = filter_input(INPUT_GET,'q',FILTER_SANITIZE_STRING) ;
$source = filter_input(INPUT_GET,'loc',FILTER_SANITIZE_STRIN G);
//enforce url, no local paths
if (!empty($source)) $PATH = 'http://'.preg_replace('@^http://@','',$source);
$FILE = fopen($PATH,'r');
$results = '';
$line_number = 0;
$TEXT = '';
if ($FILE) {
while (!feof($FILE)) {
$buffer = fgetss($FILE, 4096);
++$line_number;
$TEXT .= "<div id=\"line_$line_number\">$buffer</div>";
$loc = preg_match('@('.preg_quote($search).')@i',$buffer) ;
if ($loc > 0) {
$results .= print_results($buffer,$search,$line_number,'line') ;
}
}
fclose($FILE);
}
// takes $line as input, outputs formatted search results for $str
function print_results($line,$str,$lnum=null,$class=null) {
$style = '';
if (null != $class) $style = " class=\"$class\"";
$res = "<div$style><span>$lnum</span>: ".preg_replace('@('.preg_quote($str).')@i',"<b >$1</b>",$line)."</div>";
return $res;
}
?>

<?php echo $results;?></td></table>

funziona ma ora c'è un problema, ovvero aprendo la pgina con lo script mi mostra tutto il contenuto del file e poi se faccio la ricerca mi trova quello che deve trovare. Come posso non far vedere la lista totale?
Vorrei che venisse mostrato solo il risultato una volta cercato.
Grazie mille
