Need Search engine BADLY!

php_mindgrain

Ok,

I'm new around here and have spend my last few days searching the site for a PHP search engin that works. I havn't been too successful. Here is the lowdown: I need to Somehow:rolleyes: get a PHP based search engine into my site that can be quirried from any form. It needs to be able to search PHP files, and prefrably html files too. I would preffer it not to use MySql, but if somone could tell me how to use that (I have access to it) that would be fine as well! Phew! Glad I got that off my shoulders! 🙂 I am a typical newbie to PHP and mysql, but not to web development, I REALLY need some help here to meet deadlines! Any soloution would be fine, if someone has a script that works...And can tell me how to use it, that would be Wonderful! This is my last resort before I have to scrap the search engine entirly! I would REALLY! Appriciate it if someone could find a soloution for me! oh, one more thing, I don't really want to use the google one for searching sites, or a prepackaged one or of that sort.

Thanks!

P.S. I'd also actually like to OFFICIALLY learn PHP, so if anyone has any good resources....🙂

Well you kinda picked a potentially complex one to use as your spring board to learning PHP, especially on a deadline.

I know you said you didn't want a pre-packaged one, but have you looked at what they had at hotscripts.com? You may find a useful script there. (Sorry, I don't really have time to go into the nuances or writing of the potential complexity of the code right now, especially not knowing any details of what your search criteria is.)

Fredric...

Thanks for the gogle script/ How does it work, does it display the google page, or is the interface customizable? Also, how to I implament that script to work with forms, sorry, I am a REAL newbie! :queasy: Thanks!!!

Frederick

What the search form does is queries Googles engine to only point to your site and search your domains pages only. This allows you the power of Googles features. PHP.net uses the same method for finding items for thier site.

Ok,

Eg. Have 2 pages. Page 1 is the search form. Page 2 display the results.

In page 1, specify the search variable such as if i want to search for country Malaysia. Specify it as variable $country.

The in Page2, inside the query,

"SELECT * FROM tablecountry WHERE countryfieldname='$country%' ",

Hope that help.....

jojojo,

You're 3/4 right with this, but I don't think they're trying to query a DB at their site. I believe the intent is to be able to search the actual content on their website.

*Note jojojo, if you use the % wildcard in a DB query, you may want to use LIKE and not =...

Correct you are defender! And fredrick, I checked out PHP.NET's search feature and I was quite pleased with it, but my question is this: How can I take a google powered search, and display it in my website's template? If that is possible.....🙂

Frederick

I've tried to migrate the results into my site but I believe that they are using additional methods of grabbing results and the results need to be rendered in googles site.

You could probably build it into framesets, but I do believe you have very limited (if any at all) modification capabilities of the overall look. But google is so plain that it's easy enough to modify your site to blend them together a bit.

Frederick, I would modify your code for portability though... Your code assumes register globals is on, so it wouldn't work on my test platform, my host, and a whole bunch of others out there I imagine...

<?php 
$Your_Domain = "ronfrederick.com"; 
if (isset($_POST['search'])) { // Change to pull from the global $_POST array 
    $keyword = $_POST['keyword']; // Define from the global $_POST array
    $url = "http://www.google.com/search?q=".$keyword." site:".$Your_Domain; 
    header("Location: $url"); 
} else { 
    echo "<table border=\"0\" cellspacing=\"0\" cellpadding=\"0\">\n" 
    . "<form action=\"search.php\" method=\"post\">\n" 
    . "<tr><td>\n" 
    . "<input type=\"text\" name=\"keyword\" size=\"20\" border=\"0\">\n" 
    . "<input type=\"submit\" name=\"search\" value=\"Search\">\n" 
    . "</td></tr>\n" 
    . "</form>\n" 
    . "</table>\n"; 
} 
?>

I've tried to use for migrating the following but failed:

$lines = file($url);
$google = implode(" ",$lines);
echo $google;

Ok...I think I see where you are going, I can't alter the way google displays the pages, but then, if PHP.net does it, then why can't someone else??? This is confusing me. Do I have to pay or somthing?

Frederick

PHP.net does not do it. If you enter a keyword then select Whole Site in the drop menu, it takes you to Googles site and leaves php.net.

Frederick

I found the issue of why it would not open in you site, you need to add a %20 between keyword and site.

$url = "http://www.google.com/search?q=".$_POST["keyword"]."%20site:ronfrederick.com";
echo implode('',file($url));

The catch is, your site needs to have the same background color as google (white) so the colors will look good. Google uses hard coded colors in their scripts such as #080000. They do not use classes nor id's which would be better but nope.

Frederick

I have torn the source code apart from Googles results and have found many areas you can customize to replace and take out items so you can custmize the look to match your site.

<?php
$url = "http://www.google.com/search?q=".$_POST["keyword"]."%20site:ronfrederick.com";
$lines = implode('',file($url));

// Modify background colors of table cells
$lines = str_replace("008000","FFD700",$lines);
$lines = str_replace(" bgcolor=#e5ecf9","",$lines);
$lines = str_replace(" bgcolor=#3366cc","",$lines);
$lines = str_replace(" bgColor=#ffffff","",$lines);

// Replace classes with classes added to your style sheet
$lines = str_replace("class=j","class=Google",$lines);
$lines = str_replace("class=fl","class=Google_Links",$lines);

// Cancel out class
$lines = str_replace(" class=k","",$lines);

// Cancel out the font tags that are controlling the font sizes
$lines = str_replace("<font size=-1>","",$lines);
$lines = str_replace("</font>","",$lines);

// The following are the standard styles of the site cancelled out
$lines = str_replace(".f,.fl:link{color:#6f6f6f}","",$lines);
$lines = str_replace("a:link,.w,a.w:link,.w a:link{color:#00c}","",$lines);
$lines = str_replace("a:visited,.fl:visited{color:#551a8b}","",$lines);
$lines = str_replace("a:active,.fl:active{color:#f00}","",$lines);

// Replace googles logo with a pixel image
$lines = str_replace("/images/logo_sm.gif","Site_Images/pixel.gif",$lines);

echo $lines;
