PHP - Php Tf*idf Search Application.
Hi all, this is my first time on this forum!
I have a background with HTML and CSS but have recently started a Masters in Computer Science hoping to come out of it with the tools to get a job with PHP development. Our first assignment has somewhat 'thrown me in the deep end' as we have to construct a search engine that indexes the words of a number of documents and rank them using the TF*IDF algorithm along with the log rule associated with Information retrieval. I am completely new to PHP so the past week has been something of a crash course - This is the code I have so far: Code: [Select] <?php $filename = 'airlines.txt'; $fp = fopen( $filename, 'r' ); $file_contents = fread( $fp, filesize( $filename ) ); fclose( $fp ); //$new_contents = ereg_replace("[^A-Za-z0-9]", "", $file_contents); /*$file_contents = trim($file_contents); $file_contents = preg_replace('/\h+/', ' ', $file_contents); $file_contents = preg_replace('/\v{3,}/', PHP_EOL.PHP_EOL, $file_contents); */ $pat[0] = "/^\s+/"; $pat[1] = "/\s{2,}/"; $pat[2] = "/\s+\$/"; $rep[0] = ""; $rep[1] = " "; $rep[2] = ""; $new_contents = preg_replace("/[^A-Za-z0-9\s\s+]/","",$file_contents); $new_contents = preg_replace($pat,$rep,$new_contents); //preg_replace('~\s{2,}~', ' ', $text); $commonWords = array('a','able','about','above'........and another few hundreds cut out of this not to hurt your eyes!); $lines = explode ( "\n", $new_contents); $lines2 = implode (" ", $lines); $words = explode ( " ", $lines2 ); $useful_words = array_diff( $words, $commonWords ); /*for($i = 0; $i < count($lines); $i++) { echo "Piece $i = $lines[$i] <br />"; }*/ for($i = 0; $i < count($useful_words); $i++) { echo "Words $i = $useful_words[$i] <br />"; } //$arr=array("blah1","blah2","blah3"); file_put_contents("demo2.txt",implode(" ",$useful_words)); //$file_c = file_get_contents("demo.txt"); //$colms = explode(",",trim($file_c)); //print_r($colms); //echo $lines[2]; ?> I've got to the stage where that strips out most of the stop words when the final array is printed, but they have been replaced with spaces or something that I have not come acoss because as you may see I had a bit of trouble originally stripping the punctuation marks. I'm hoping someone can point me in the direction as to how to organise the words I have left after the stripping of stop words which are of no use during the search. I need to store those words into another array and index them which says how many times they appear in that document. I've come across the function array array_count_values ( array $input ) on the manual but I'm not sure about the best way to use it. I've attached the files I've used if that helps. Any help would be greatly appreciated! Similar TutorialsHello, I had a small php , mysql application & I need to include the search to it. example of search below: By driver: Driver 1 Driver 2 Driver 3 By Time: Morning Evening Noon By Level: Level 1 Level 2... each one is a checkbox so any help on how to implement this search? Thanks in advance Hi, I need a small help. Here is my situation. I am using a MVC application (e.g. Joomla or Drupal) which has a .htaccess redirect rule that all requests are passed through index.php file. That's normal and this is my main application. Now I installed another application within the application folder structure. What I want do do here is to allow opening the third party application URLs after one logged into my main application. Can anybody provide me some pointers to do the same? Please let me know if you need any further information on this. Any solution irrespective of framework will work. Thanks!

One is to read ten chapters a day, one chapter from each of the bookmarks. Type in what day you are on and the program will show you on each of the lists as to what chapter you are suppose to be on. Also want to show statistics that will display how many times the Bible has been read with a break down of all 66 books of the Bible.

I am building program to manage payment/monthly payments. I've ran into an issue that I haven't been able to overcome and need some help. I've been lurking for a while and decided it was time to ask you guys...Here's the issue: I have a table 'payments' that contains scheduled payments that looks like: id clientid paymentduedate balance expected pending 367 112233 4/16/2011 1030.00 257.50 Y 368 112233 5/16/2011 1030.00 257.50 Y 369 112233 6/16/2011 1030.00 257.50 Y 370 112233 7/16/2011 1030.00 257.50 Y What I need to do that I haven't figured out is to adjust the expected amount according to the payment, update the status to N (not pending) without affecting the later expected payments. For example: they make a payment of $257.50, applies that to row 367, sets the status to N, but leaves the other status' to Y (for obvious reasons). the make a payment of $250.00, leaving the balance at $7.50, so lets add $7.50 to row 368, mark 367 status to N the make a payment of $300.00, leaving the expected balance at $0.00 for row 367, but adjust the balance for row 368 to $215.00 Any ideas? Thanks Hey all I have an error in my Facebook application and I'm not sure what's wrong (New to PHP). The error output is: Code: [Select] Warning: array_rand() [function.array-rand]: Second argument has to be between 1 and the number of elements in the array in /home/app/view.php on line 15 And the PHP lines are as follows: $friends = $facebook->api('/me/friends'); print_r(array_rand($friends, 3)); Hello I am making a game trading web application for class. Here are the requirements: You must be able to register and log in, you must be able to list games you have to trade and games you want, you must be able to search users that want games you have and users that have games you want, you must be able to accept and make trades, on trade finalization screen you must be able to rate user 1-5, view the users shipping address, and leave a comment on the users page. You do not have to be able to view other users pages, but on your home page you must be able to view your average rating. I am the most advanced programmer in my group so this has been a little tough. I have a login page and a registration page, I have a user home page, a add games page, a view feedback/ratings page, and a my games page where you can delete games. What I'm stuck on is the page that allows you to search users by games they want and games you want, and the trade finalization page. On the search page I would like to combine the functionality of searching for users with games you want and games they want with the ability to make a trade offer. The way we have it drawn up is using radio buttons to select either show people with games I want and show people wanting my games. When one is selected it will populate a list of usersnames in a drop down menu that fit whichever choice was made. We drew up four list boxes that populate lists when we select a user name, one box populates the games they have, one populates the games they want, one populates the games I have and one populates games I want. We want to be able to select game titles and move them to a list box of games I want and another to a list box of games willing to trade, lastly a submit offer button. We are debating on if this is the best set up given the requirements needing to be met. I think there is more here than what we need, we have 1 week to do this and I am doing all the programming so I am looking for the easiest way to search users that want games I have/have games I want and display the results giving me the option to select games to trade and make an offer. We are also arguing on if we have to use JavaScript to do this or if it can all be done within php. The trade finalization page would have a drop down menu where you select the user name of completed trades and upon selection lists will be populated of games they gave, games I gave and the address to send the game. It will also have a form where we can rate the user and leave a comment. This page I need help with cause again we disagree on having to use JavaScript or not. We are using phpMyAdmin and the db tables we have a tblgame - list of games I have added tblgamestatuscode - gives game a code that determines if it is wanted, to trade, or traded tblmember - member registration tblplatform - platform the game is on (Xbox, Xbox 360, Playstation2, Playstation3, PC, and Wii) tbltransaction - date traded and a status change code tbltransactiondetail - gameID and trans ID tbltransactionparty - memberID, transID, rating, comments, status change accepted We are also using adodb. Please help if you can. I will gladly give more information if needed. This topic has been moved to Miscellaneous. http://www.phpfreaks.com/forums/index.php?topic=353630.0 I am looking to save the user's access of an application. For instance, when they log in, I create a record in the "track_login" table which includes information such as the requesting IP, the user's ID, the date, (not the user's password), etc. And then for every page they visit, I store a record in the "track_page_viewed" table which includes a FK to the "track_login" table and also includes additional information about their request.
Both the track_login and track_page_viewed tables are currently in the same database as used by the primary application.
So far, so good.
Next, I want to start tracking when a user does special tasks such as when they forget their password and request that a new one be emailed to them. Or maybe when they attempt to login with an invalid username and password. Currently, I just included another table called "track_special" which includes the data, the type of special request, etc.
Now, I am thinking of adding three other things to track:
General PHP errors
MySQL errors
Try/Catch errors which I did not expect to happen
One option is just to add these to my "track_special" table or maybe make one or three new tables in the same database.
But is this a good idea? If I have a SQL error, do I really want to store the error in the same database? Maybe I should use a separate database called "myTrackerDB", and include all the above tables in that database? Or maybe I should just write the data to a flat file, and parse the file on a regular basis, and then store the information in the database?
Please provide any recommendations, guidance, suggestions, criticism, etc. Thank you
My application has 3 user types. Admin , User and Super Admin. Users can register as either Admin or User. Each user type has different UI and functionality. The problem: If a particular type of user reports a problem/bug in his/her login, it is difficult to pin point to the exact problem. So if I could able to login as that user, then it will be very easy to point out the bug/problem. So I'm looking for some kind of master password. Using any username and the master password I should be able to login AS that user. Any suggestions..? So I have an webapp which has a built in proxy checker. However because I didn't write the code I am kind of confused on whats going on. I have a small amount of knowledge on php been looking all over the net to find a solution. So this file called (proxy_check.php) keeps causing my index.php to show the 404 designed page. The file is required in the index.php file. I believe its something to do with the $reponse variable. Please help
<?php
# Visitor proxy check snippet
$v_ip = $_SERVER['REMOTE_ADDR'];
$arContext['http']['timeout'] = 10;
$context = stream_context_create($arContext);
$response = file_get_contents('http://www.shroomery.org/ythan/proxycheck.php?ip='.$v_ip, 0, $context);
if ('Y' === $response) {

Hello guys,
I am an intermediate level PHP programmer and digging my way through this giant universe of programming,
During this term, I have been able to build logics for problems (simple ones though) using my own thinking etc etc..
Anyway, I fully understand that I still have a lot to learn and I dont have any teachers to guide me through. So I wanted to request that If i submit an application for a quick review, like what I missed, how should I do it next time and guidance like this will seriously help me through.
I know it will be a pain reviewing someone else's apps but i dont have elsewhere to go..
I've been developing an application for some time now. It's come to the point to populate the database with accurate information. I've been searching for a list of City, State, Zip, Long & Lat for each. How can I find something like this? I see tons of them for sale, 79 bucks or so, but I don't want to pay. How do most of these people get their data? Thank you I need to develop a web based bulk SMS application to integrated into my existing website which is written in PHP.
That means I shall use my authentication script to lock it down.
The application should be able to pull phone numbers from MYSQL database, and from a specified list.
If you can do this or need more information, reach out to me.
Thanks.
