PHP - Delete Old Session File
hi friends!!
in php > 5 i use "session_regenerate_id(TRUE)" in order to generate a new session file and delete old one. In php 4.x the TRUE parameter doesn't exist: old files will be accumulated until the garbage collector will cleans all. How can I delete old session file in php 4.x having regenerated the new one? Similar TutorialsHello, I have many session variables and instead of unsetting them all I want to know if there is some code to remove all current sessions apart from a couple of them. Cheers hey guys im using a session cookie to store a user_id, only if user has clicked to remember me on the login form...that way when autenticating it checks id in db and if matching a user it logs in automatically.
now the problem i want to just remove user_id from a session cookie. if i use the code below to delete the user_id session then it will remove all session cookies.
is there a way just to remove 1 session cookie? thank you
// create session cookie session_start(); session_set_cookie_params('3600', 'C:\Users\Ricky\Desktop\www\BiSi\private\tmp\session', 'http://127.0.0.1/', true, true); ini_set('session.gc_probability', 1); session['user_id'] = 1; //delete session cookies setcookie (session_name(), null, time() - 3600); session_regenerate_id(true);any help/advise would be greatful...cheers guys I have the following session variables for each item in a cart, which gets updated each time an item is added from the catalog // Register the session variables $_SESSION['ses_basket_items']=$ses_basket_items; $_SESSION['ses_basket_name']=$ses_basket_name; $_SESSION['ses_basket_amount']=$ses_basket_amount; $_SESSION['ses_basket_price']=$ses_basket_price; $_SESSION['ses_basket_stockcode']=$ses_basket_stockcode; $_SESSION['ses_basket_image']=$ses_basket_image; $_SESSION['ses_basket_size']=$ses_basket_size; $_SESSION['ses_basket_sizechoice']=$ses_basket_sizechoice; $_SESSION['ses_basket_id']=$ses_basket_id; I have a current cart page which loops through the sessions and displays them in a form. I have a check box for each item with the name="remove[]" and the value is the itemID which is the $ses_basket_id of item in the session. I have a select box with name="size[]" and the value is the users selected size for each item in the session which is $ses_basket_size Finnally I have a quantity text box with name="quantity[]" and the value is the users quantity value selected which is $ses_basket_amount. After all the looping through the products displaying each item in a row I have an update cart submit button name="change" outside the loop. What I want to know is how do I setup to perform each of these actions for each item in the session, how do I create the foreach loops for each array to delete or modify the correct items in the session if they are modified. I have the code to perform each task but dont know how to loop it through for each item in the session affecting only the correct session items. so if I have 3 items in the session for example, and I want to change the size of item 1, remove item 2 and change item 3 for quantity 1 to quantity 3 with only the 1 form and change button for all items and actions? Hope that makes sense any help with this would be appreciated. Hey guys!

Something like this: If, i give string: Code: [Select] ### Start of content 0 ### Then it will delete this line to the Code: [Select] ### End of content 0 ### Hope you can help! All the best: Mart L. I am trying to delete a file via unlink(). It's a .html file, stored in a folder on its own. // current directory $dir = dirname(__FILE__); $dir = str_replace('classes','',$dir); $file = str_replace('./',$dir,$fr['location']); unlink($fr['location']); if(!unlink($file)){ echo 'err'; } if(file_exists($file)){ echo 'ok1'; } The $fr['location'] stores the real location, as ./uploads/1303577497/barebones.html. I've tried every combination I can think of to delete it. I've even deleted it from FTP and re-uploaded it, in case it was a permissions issue, but it refuses to go. When I file_get_contents it, it appears as existing. Can anyone help? I want to add text to a file, getting it printed out in index.php and later want to edit/delete per row. I give codes page wise. first the form to take data: add.php: Code: [Select] <?php ?> <form method="post" action="add_data.php"> <fieldset> <legend>Student List</legend> Name : <input type="text" name="uname" /><br> Content : <input type="text" name="age" /> <br> <input type="submit" name="submit" value="send" /> </fieldset> </form> Next adding text to a file: add_data.php: Code: [Select] <?php $id = 1; if (file_exists("data.txt")) { $fp = fopen("data.txt", 'r'); $str = fread($fp, filesize("data.txt")); $str_arr = explode("|", $str); foreach ($str_arr as $rec) { if ($rec) { $id++; } } } $mode = (file_exists("data.txt"))? "a" : "w"; $fp = fopen("data.txt", $mode); $line = $id . "--" . $_POST['uname'] . "--" . $_POST['age'] . "|"; $res = fwrite($fp, $line); fclose($fp); header("location:index.php"); ?>In the index.php, I'd like to fetch data and edit them per row: Code: [Select] <?php $fp = fopen("data.txt", 'r'); $str = fread($fp, filesize("data.txt")); $str_arr = explode("|", $str); echo "<table border='1'>"; echo "<tr><td>ID</td><td>Name</td><td>Age</td><td>Option</td></tr>"; foreach ($str_arr as $rec) { if ($rec) { $rec_arr = explode("--", $rec); echo "<tr>"; foreach ($rec_arr as $col) { echo "<td>$col</td>"; } print "<td><a href=\"edit.php?id=$id\">Edit</a>/<a href=\"delete.php?id=$id\">Delete</a></td></tr>"; } } echo "</table>"; echo "<a href=\"add.php\">Add Data</a>"; ?> Next I want to Edit per row: edit.php: Code: [Select] <?php $fp = fopen("data.txt", 'r'); $str = fread($fp, filesize("data.txt")); $str_arr = explode("|", $str); foreach ($str_arr as $rec) { if ($rec) { $rec_arr = explode("--", $rec); $id = $rec_arr[0]; $name = $rec_arr[1]; $age = $rec_arr[2]; if ($id == $_REQUEST["id"]) { echo "<form action='edit_data.php' method='post'>"; echo "Name :<input type='text' name='uname' value='$name' /><br>"; echo "Age: <input type='text' name='age' value=$age /><br>"; echo "<input type='hidden' name='uid' value=$id />"; echo "<input type='submit' value='Edit'>"; echo "</form>"; } } } ?> From edit.php to edit_data.php where I practically try to edit per row: Code: [Select] <?php $fp = fopen("data.txt", 'r'); $str = fread($fp, filesize("data.txt")); $str_arr = explode("|", $str); foreach ($str_arr as $rec) { if ($rec) { $rec_arr = explode("--", $rec); $id = $rec_arr[0]; $name = $rec_arr[1]; $age = $rec_arr[2]; if ($id == $_POST['uid']) { $new_str = $id . "--" . $_POST['uname'] . "--" . $_POST['age'] . "|"; } else { $new_str = $id . "--" . $name . "--" . $age . "|"; } } } fclose($fp); $fp = fopen("data.txt", 'w'); fwrite($fp, $new_str); fclose($fp); ?> The mechanism is simple. Taking datas from a form, explode them to an array and get them into col/row pattern to edit and delete them. But my problem is when I want to edit in index.php page, specially in this part: Code: [Select] print "<td><a href=\"edit.php?id=$id\">Edit</a> It says, undefined index. But I try to catch this $id in the edit.php page, in this manner, as you see in my code: Code: [Select] foreach ($str_arr as $rec) { if ($rec) { $rec_arr = explode("--", $rec); $id = $rec_arr[0]; $name = $rec_arr[1]; $age = $rec_arr[2]; if ($id == $_REQUEST["id"]) { echo "<form action='edit_data.php' method='post'>"; echo "Name :<input type='text' name='uname' value='$name' /><br>"; echo "Age: <input type='text' name='age' value=$age /><br>"; echo "<input type='hidden' name='uid' value=$id />"; echo "<input type='submit' value='Edit'>"; echo "</form>"; } } } Have I done any mistake here? If anyone points out, I'll be obliged. Hello all. In lack of better terms, I am a programming noobie when it comes to designing code. I can look at a code and figure it out, but basically I am trying to figure this out. I host a website from home, running on a server 2008 machine, with apache/php, basically to share files from home, work, friends house, wherever I need. I do have a FTP for this, but I also want to be able to upload files via http. I actually want to be able to set a time or date that the file will auto-delete. Such as, I select a file from my local machine, set the deletion time to 1 hour/60 minutes/3600 seconds, whatever, upload it to the site, and it spit back a url that I can access that file for that set amount of time. It would be great to implement something like bit.ly to shorten the link, or even something to randomize the link. Any ideas on that from anyone? Willing to donate (paypal) a little bit if someone can actually help me out, or point me in the right direction. A week on google has proved useless. Thanks so much.

I have tried many snippets and really need help. Hey all need some help with the subject title. Have a user text file with all information(Name, address, passwords, etc..) Need to be able to select the user based on Checkbox selection then hit delete button and all users checked will be removed from the txt file and thus removed from HTML page. Im using PHP to show contents of the txt file into my HTML page. So far i have: <?php $file = fopen("user.txt","r"); echo '<table border="0" width="100%"> <tr> <th>Select</th> <th>Username</th> <th>Password</th> <th>FirstName</th> <th>LastName</th> <th>Email</th> <th>Address</th> </tr> '; while(!feof($file)) { $user = explode(":", fgets($file)); echo '<tr> <td><input type="checkbox" name="chkDelete" id = "chkDelete" value="select" /></td> <td>' . $user[0] . '</td> <td>' . $user[1] . '</td> <td>' . $user[2] . '</td> <td>' . $user[3] . '</td> <td>' . $user[4] . '</td> <td>' . $user[5] . '</td> </tr>'; echo '</table>'; fclose($file); ?> Am unsure as to how i would go about doing this, help would be greatly appreciated! Thanks in advanced, Daniel. Hi All, I am using the uploadify script available at http://uploadify.com/ Now I can get the file uploads working fine with the script below: Code: [Select] <?php session_start(); ?> <link href="/uploadify/uploadify.css" rel="stylesheet" type="text/css" /> <script type="text/javascript" src="/uploadify/jquery-1.3.2.min.js"></script> <script type="text/javascript" src="/uploadify/swfobject.js"></script> <script type="text/javascript" src="/uploadify/jquery.uploadify.v2.1.0.min.js"></script> <input id="fileInput" name="fileInput" type="file" /> <script type="text/javascript">// <![CDATA[ $(document).ready(function() { $('#fileInput').uploadify({ 'uploader' : '/uploadify/uploadify.swf', 'script' : '/uploadify/uploadify.php', 'cancelImg' : '/uploadify/cancel.png', 'auto' : true, 'folder' : '<?php echo $_SESSION['filepath']."/downloads/"; ?>', 'multi' : true }); }); // ]]></script> The problem that I am having is that I also store the mysql connection details in session vars (they change depending on who logs in). I have tried a number of ways of "passing" these session vars to the uploadify.php file which does the grunt work of the uploading, but I can never seem to access them. I obviously dont want to pass them to the uploadify.php script through the js because that will show my credentials in the source code. So, the question is, how can I access these session vars in the called file. I assume its a combination of session_write_end() and session_start() but I havent got the right combination yet. |
