Web Site Search Facility

Anon

Hi Guys,

I want to add a search engine facilty to my web site that will search the content on the website not the rest of the Internet.

Any ideas where I can start? I'm a novice to PHP and any help would be gratefully appreciated.

Many thanks ...

One way is to set an array = to all the pages you want to search. Then go through them one by one. Open each file and go through them one line at at time . do a string match for . keyword . and return it if it matches.
Hope that helps
If you need any more help post back

Heres some code :

<?
// SITE KEY WORD SEARCHER - Alan Fox May 2002

// LIST OF ALL SEARCHABLE PAGES - UPDATE HERE
// just add new pages as below no othes changes needed
// NOTE : include folders above index eg $files[] = "tetris/tetris.htm"
// NOTE : You will get an onscreen error if page doesnt exist !
// so update this page if you change any page names
// make sure all pages have the following
// <title> Name of file here </title>
// AND
// <meta NAME="description" CONTENT=" Description here, can use for new line. No double quotes only single ">

$files[] = "home.htm";
$files[] = "about_us.htm";
$files[] = "help/all.htm";
$files[] = "array.htm";

$real_search = $search;
$search = substr($search, 1, 8);

$count=0;

echo "Searching for ".$real_search.".... ";
echo "<hr>";

foreach ( $files as $file )
{

// open each file
if(! $open_file = file($file))
{
// echo "CANT OPEN ";
}
else
{
//echo "OPENED FILE " ;

foreach($open_file as $a)
{
//echo "".$open_file[$a]." ";

if ( eregi("<title>(.*)</title>", $a , $out)) {
$name = $out[1];

}
if ( eregi('<meta NAME="description" CONTENT="(.*)">', $a, $out)) {
//$text = $out[1];

}

// if(preg_match("/.$search./",$a) )

if(preg_match("/.$search./",$a) )
{
//arraydesc[$file] = $text;

$arraydesc[$file] .= $a;
$arraytitle[$file] = $name;
$array[$file] += 1;
if($array[$file] == 1)
{$count += 1;}
//$text = $a;
//echo "FOUND alan IN ".$file." ";
}

}

<?php

if ($array[$file] > 0)
{
//////////////////////////////////////////////////////////////////////////
// RETURNED PAGES
?>

 <div align="left">
<p>
<font color="#FF6600" size="1" face="Verdana, Arial, Helvetica, sans-serif"><b><?=$arraytitle[$file]?></b><br>
<font color="#003366">

<?echo "...".$arraydesc[$file]."..."?> 
<a href="http://www.homepage.com/<?=$file?>" target="main"><?=$file?></a>

</td></tr>

<?php
$text = "";
$name = "";

////////////////////////////////////////////////////////////////////////////
}
}

} //end of loop
if($count == 0)
{
echo "Sorry there were no pages found containing the word ".$real_search." ";
}
else
{
echo " ".$count." pages found in total matching ".$real_search." ";

}

?>
