parsing a text file – explode and unserialize?

@2dazedMay 30.2006

Hi,

I have a log file containing a list of serialized data, as shown here:

~~[url]~~http://designerdeveloper.net/log.txt[/url]

The format is:

FILEID|||serialize($data)
FILEID2|||serialize($data2)

I need to decode this data into the following:

Field 1 : Value
Field 2 : Value
etc.

I am not sure on how to do this – I think I should first explode the data with the separator “|||”, and then unserialize it, but I am not sure how.

Any help would be greatly appreciated.

My second task is that I'm trying to replace the field numbers (e.g [1] , [2] , [3]) with my own field names (e.g. name, time, address)

here is the code I've written so far:

[CODE]
 <?php
 session_start();
 if ($_POST['txtUserId'] === 'admin' && $_POST['txtPassword'] === 'admin') {
 
 $_SESSION['basic_is_logged_in'] = true;}
 else
 {$_SESSION['basic_is_logged_in'] = false;}
 
 
 
 // is the one accessing this page logged in or not?
 if (!isset($_SESSION['basic_is_logged_in']) 
 || $_SESSION['basic_is_logged_in'] !== true) {
 
  // not logged in, move to login
  ?>
 
 <html>
 <head>
 
 <title></title>
 
 
 
 </head>
 
 <body>
 <form method="post" name="frmLogin" id="frmLogin" action="testexplode2.php">
 <table width="400" border="1" align="center" cellpadding="2" cellspacing="2">
 <tr>
 <td width="150">User Id</td>
 <td><input name="txtUserId" type="text" id="txtUserId"></td>
 </tr>
 <tr>
 <td width="150">Password</td>
 <td><input name="txtPassword" type="password" id="txtPassword"></td>
 </tr>
 <tr>
 <td width="150">&nbsp;</td>
 <td><input type="submit" name="btnLogin" value="Login"></td>
 </tr>
 </table>
 </form>
 
 
 </body>
 </html>
 
 
 
 
 
  <?php
  exit;
 }
 
 ?>
 
 <html>
 <head>
 
 <title></title>
 
 
 
 </head>
 
 <body>
 
 
 <?php
 
 
 $file = file('log.txt');
 array_multisort($file, SORT_DESC);
 foreach ($file as $line) 
 {
 
  $lines = explode("|||", $line);
 
  print $lines[0]; 
  print '<pre>'; 
  print_r( unserialize( $lines[1] ));
  print '</pre>'; 
 }
 
 ?>
 
 </body>
 </html>
 [/CODE]

please help!

You can see how this code works at the moment at [URL=http://designerdeveloper.net/vincent/testexplode2.php]http://designerdeveloper.net/vincent/testexplode2.php[/URL]

@bokehMay 31.2006 — #One possible method is to define constants (with human readable names) and assign them with numeric values that correspond with your array keys.

[code=php]<?php
 
 $file = 'http://designerdeveloper.net/log.txt';
 $output = array();
 
 foreach(file($file) as $line)
 {
 list($k, $v) = explode('|||', trim($line));
 $output[$k] = unserialize($v);
 }
 
 define('first_name', 1);
 
 foreach($output as $sub_array)
 {
 echo '<p>'.$sub_array[first_name].'</p>';
 }
 ?>[/code]
