    Hey
    I want to create a very simple file browser, so that, it reads all the sub-folders which are places in a directory, and the files inside the sub-folders (It reads only files inside sub-folders and list them in simply. ) Also, it creates a directory (any name) inside each sub folder.
    My Following code reads on the files inside the main directory, it does not read the files inside the sub-folders.. I appreciate any help.


    <?$path = "./";$dir_handle = @opendir($path) or die("Unable to open $path");while ($file = readdir($dir_handle)) {if($file == "." || $file == ".." || $file == "index.php" )continue;echo "<a href=\"$file\">$file</a><br />";}closedir($dir_handle);?>

    There are many websites which offer free sms from website to mobile phone devices. I want to ask what is the technology behind that? Is it some SMS gateway? If someone want to create this service, is it free ? I want to know more about it, if someone can give me more information?Thanks

    While dealing with such a links in php

    page.php?id=1
    i dont want that someone access this page directly using page.php..
    i can give some custom message incase someone try to access page like:
    page.php
    okay i can make it by using if condition etc..
    but the other problem is that, if someone try to access like, 
    page.php?id=
    in this case (where id is not given, but there's only "?id= " which makes no sense.. in that case i want to make some custom msg etc. how i can handle this situation?
    Regards

    suppose i have a page, page.php?part=1 there i have some text fields. user will give input, but after taking input, it will not put the data in mysql .. but it will take to the next step.. page.php?part=2 (if any field is left blank, it will not go to next page.. ) . and there also some fields.. after the user has filled that form also, then it will insert all data (from part1 and part 2) in mysql. i want to ask, how i can collect data from 2 pages and put in mysql at once.

    Can somebody help me in creating a very simple javascript.. for example, the following code is example to delete a row from mysql.. all i want to do is.. that, when i click on delete, it gives a popup window , asking me if i really want to delete the row.. if i say Yes then it takes the action.. but if i say no then it takes back.'

    $result = mysql_query("select * from comments order by id desc limit 10");//the while loopwhile($r=mysql_fetch_array($result)){//getting each variable from the table$id = $r["id"];$self = $_SERVER['PHP_SELF'];echo $r["comment"];echo "<br />";echo "<a href = \"$self?id=$id\">delete</a>";}if(isset $_GET['id'])){$id = $_GET['id'];// --------- here code to connect to mysql and select database -----------$query= mysql_query("delete FROM comment where id =$id")or die(mysql_error());}

    Im using the following code, for very simple work.. it simply gets and print the comments which are stored in the database.
    Now it will show like
    comment 1.
    comment 2.
    comment 3. etc etc

    i want to add 'delete' option that i can delete any comment.
    it displays like

    comment 1. Delete
    comment 2. Delete
    comment 3. Delete
    So that when i click on delete, it simply deletes the comment and print the remaining comments.
    Its very simple. i hope you understand.

    $result = mysql_query("select * from comments order by id desc limit 10");//the while loop
    while($r=mysql_fetch_array($result))
    {
    //getting each variable from the table

    echo $r["comment"];
    echo "<br />";

    }
