PHP - Php Multi Language Search Engine

I thinking about building a search engine just as a fun project and a way to develop my skills.  However I'm not sure where to start... 

I want it to be a comparison search engine for computer parts so say the user type in "RAM" it would display results from PC World, Ebuyer, etc.  I was thinking of using cURL but how do I know where the search results are on each page.  For example say  I get a html page of results from PC World and store them in a variable how do I then know what to strip out to get the results I want?  Would I just have to look at the source code?  Also would I then have to work this out for each site I wanted to search from and have a different method of getting the results from search site?

If anyone has done anything like this in the past and could give me some advice that would be great. 

Thanks

Hi, I have a script which searches the MySQL database. It outputs the result which is a business name, but I need the business name to be in a link so the user can click on it and go to another page to find out more information. However the business name is not included in the link, but the $value is.   Here is my script

<?php
include 'init.php';

// normal search
$result_tb = "";
if (!empty($_POST['SEARCH']) && !empty($_POST['search_value'])) {

   $e = $_POST['search_value'];

   $query = 'SELECT aquaticCenterName FROM reviews WHERE ' .
           "aquaticCenterName LIKE '%$e%' OR " .
           "town LIKE '%$e%' OR " .
           "county LIKE '%$e%' OR " .
           "country LIKE '%$e%' OR " .
           "rating LIKE '%$e%' ";

   $query_result = $con->query($query);

 $result_tb = '<div>';
   while ($rows = $query_result->fetch_assoc()) {
      foreach ($rows as $k => $v) {
         $result_tb .= '<a href="reviewResults.php?aquaticCenterName= . $v . ">' . $v . '</a><br>';
      }
   }
   $result_tb .='</div><hr>';

   $con->close();
}
?>
<?php
include 'includes/overall/header.php';
include 'includes/logo.php';
?>
      <form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
         <table>
            <tr>
               <td>
                  <input type="text" name="search_value" size="30" maxlength="30"/>
               </td>
               <td>
                  <input type="submit" name="SEARCH" value="Search"/>
               </td>
            </tr>
         </table>
      </form>
      <?php echo $result_tb; ?>
<?php
include 'includes/overall/footer.php';

But when I click on the link, I get this in the address bar   reviewResults.php?aquaticCenterName=%20.%20$v%20.   How do I get this to read   eg, reviewResults.php?aquaticCenterName=PaulsAquaticCenter   Many Thanks   aquaman

Php search engine for my site

I have a Romanian based language site: http://www.firmelavedere.com with informations about business companies.

I implemented a simple php search engine for my website on pages like this on the top right corner:
http://www.firmelave...aj-Zalau-15.php

I want to add a new radio box field to select language for displayed text.

Is there a possibility to integrate Google Site Search with more languages?
How can i do that?

I need some code suggestions, to make this script run fast.

Thanks all.

Hi, I'm having two issues with my Search engine for my website. It is created to search through my database (it doesn't crawl through pages). The first problem I'm having is when I type in for example:
Super Mario Bros
and there is a row in my table with a field called Super Mario Brothers
this row is not included as a successful result to the search. I need to somehow modify my code to search every word in every table cell in the database.

So another example. I have 5 rows, each with one cell, named as follows:
One
Two
Three
Four
Five
If I was to type in the search box:
One Two Three Four Five
it should display all rows (it obviously doesn't do that right now lol)

The second issue has to do with my sql query.
It looks like this:

$query = "select * from sheets where artist like \"%$trimmed%\" OR title like \"%$trimmed%\" 
  order by artist"; 
 $numresults=mysql_query($query);

I need this query to search in the columns artist and title (like it is doing above) AS WELL as search only those rows that have an active status set to 'yes'.
I tried to type something like:
$query = "select * from sheets where active='yes' && artist like \"%$trimmed%\" OR title like \"%$trimmed%\" 
  order by artist"; 
but this obviously causes problems. How do i require the query to include rows that are active, but have it look through artist OR title as well?

Here is my code below. Any insight appreciated. Will be working on it til someone is available. Thanks

<?php
  include_once('inc/functions.php');
  // Get the search variable from URL

  $var = @mysql_safe($_GET['q']) ;

Can someone help me with my code. Used a tutorial as aid but still struggling. Basically I have a table called student. I created a search engine so that if a user searches for either the sname,fname or sno of a student then that student would appear. Apart from some notices I got it working and displaying students when searching for only their sname. Now, I want to be able to make it possible to find a student by searching either sname,fname or sno and I'm getting errors. Can anyone have a look at my code:

Code: [Select]

include 'includes/config.php';
include 'includes/functions.php';

connect();




//explode search term
$search_exploded = explode(" ",$search);

else
$construct .= "OR sname,fname,sno LIKE '%$search_each%'";



}

First time attempting this, so any tips on what I did wrong would be great. Thank you in advance.

Hello,

I would like to build a php search engine against a mysql database. I am looking for a tutorial but haven't been able to find any good ones. Any ideas of where I can find one? I need one where I can search with several words and if it has the stemmer.class.inc and so on would be great also.

thanks, df

I made a search engine to search my database for specific users ( well I used a tutorial ). I'm not getting any errors atleast when loading the page which is a first for me. However, now I am tackled by something new. When entering the keywords and submitting the search I get:
Access forbidden!

You don't have permission to access the requested object. It is either read-protected or not readable by the server.

If you think this is a server error, please contact the webmaster.
Error 403
127.0.0.1
04/30/07 11:09:21
Apache/2.2.16 (Win32) PHP/5.3.3

Which is odd for me because I am using the same config.php with connection code to connect to the db which I used with all my other pages. And in those pages I have been able to add/delete/edit and display records from the database tables. Does this have something to do with it being a search engine?

Here is my code:
Code: [Select]

<html>
<head>

<h2>Search</h2>
 <form name="search" method="post" action="<?=$PHP_SELF?>">
 Seach for: <input type="text" name="find" /> in

 //If they did not enter data then they receive an error
 if ($find == "") 
 { 
 echo "<p>You forgot to enter a search term"; 
 exit; 
 } 
 
 // Otherwise connect to database
include 'includes/config.php';
include 'includes/functions.php';

connect(); 
 
 // filtering
 $find = strtoupper($find); 
 $find = strip_tags($find); 
 $find = trim ($find); 
 
 // search for term in specified field
 $data = mysql_query("SELECT * FROM student WHERE upper($field) LIKE'%$find%'"); 
 
 // display results
 while($result = mysql_fetch_array( $data )) 
 { 
 echo $result['fname']; 
 echo " "; 
 echo $result['sname']; 
 echo "<br>"; 
 echo $result['sno']; 
 echo "<br>"; 
 echo "<br>"; 
 } 
 
 //Counts number or results and display message if there we're non
 $anymatches=mysql_num_rows($data); 
 if ($anymatches == 0) 
 { 
 echo "Sorry, but we can not find an entry to match your query<br><br>"; 
 } 
 
 //And we remind them what they searched for 
 echo "<b>Searched For:</b> " .$find; 
 } 
 ?>

Any ideas? Thanks in advance

Hi Everyone.
 Am about to create a search engine for my project using php and mysql. My question is that > Do i have to keep creating tables and entries in the  database to contain all the topics to be searched for? Or is there another way to go about it? cos i dont think i can really enter all the search topics and their web address and also their keywords.   
Thank You.
