multiple keywords

Post by sulen »

I am trying to modify my search script to do the following :

for eg. if I search for the keywords <tax rate> separated by a delimiter ' ' it should show all pages that have the tax separately, rate separately as well as the combination of tax and rate in them. Can anyone help me on this. I know i am doing something really stupid. Please advise.

the code is

Code: Select all

$search_term = explode(' ', $string); // explode info
$num_keywords = count($search_term); 
 
function search_dir () {
global $cur_path, $dir_depth, $matches;
if ($matches > 100) { return; }

$s_dir="rfp";
for ($c=0; $c<=$dir_depth; $c++) { $s_dir .= $cur_path[$c]; }

$dhandle=opendir("$s_dir");
while ($file = readdir($dhandle)) {

if (($file!=".") && ($file!="..")) {
if (is_file($s_dir.$file)) {
$file_ext = substr($file, strlen($file)-3, 3);
if ($file_ext == "php") search_file($s_dir.$file);
}
elseif (is_dir($s_dir.$file)) { 
$cur_path[++$dir_depth] = ($file."/");
search_dir();
$dir_depth--;
}
}
}
}
function search_file ($file) {
global $cur_path, $dir_depth, $results, $r_text, $r_title, $matches, $search_term;

$s_dir="rfp";

for ($c=0; $c<=$dir_depth; $c++) $s_dir .= $cur_path[$c];

$f_size   = filesize($file);
$f_handle = fopen($file, "r");
$f_data   = fread($f_handle, $f_size);

if ($text = strstr($f_data, 'SSIGNORE')) return;

$f_dlc    = strtolower($f_data);
$t_text   = ""; 
$in_tag   = 0;
  if ($text = strstr(strip_tags($f_dlc), $search_term[$i])) {
    $results[$matches] = $file;
    $text = substr($text, 0, 200);
    $text = str_replace ($search_term[$i], "<font color="#127A84"><b>".$search_term[$i]. "</b></font>", $text);
    $r_text [$matches] = "...". $text. "...";
    $t_start = strpos ($f_dlc, "<title>") + 7;
    $t_end   = strpos ($f_dlc, "</title>");
    $r_title[$matches++] = substr($f_data, $t_start, $t_end-$t_start); 
    }
  fclose($f_handle);
  } 

search_dir (); 
for ($i=0; $i<$num_keywords; $i++){

echo $search_term[$i];
search_file ($file);
<table width='100%' border='1' bordercolor='black' style='border: 1px'>
<tr>

Code: Select all

$dir_depth=0;
$matches=0;
$cur_path = array("/");
$results  = array("");
$r_text   = array("");
$r_title  = array("");

$search_term[$i]=strtolower($search_term[$i]);
if (strcmp($search_term[$i], "")!=0) { search_dir(); }
}
$c="#ffffff";
for ($a=0; $a<$matches; $a++) {
  if ($c=="#ffffff") {$c="#ffffff";} else {$c="#ffffff";}
  echo "<tr><td class="a" align="center" bgcolor="$c">";
  echo "<a class="five" href="$results[$a]" title="Go To This Page"><font color="#127A84">$r_title[$a]</font></a>";
//  echo "<br>&nbsp;<code>$results[$a]</code>";
  echo "</td><td class="a" align="left" bgcolor="$c">$r_text[$a]</td></tr>";
  }
echo "</table><br><p>$matches Matches.<br><br>";
