Making a full directory into .zip and unzipping it on server! http://www.nuhil.net/blog/cms/reduce-time-in-uploading-and-deleting-when-managing-files-through-ftp-making-a-full-directory-into-zip-and-exracting-it http://www.nuhil.net/blog/cms/reduce-time-in-uploading-and-deleting-when-managing-files-through-ftp-making-a-full-directory-into-zip-and-exracting-it#comments Sun, 01 Nov 2009 17:07:21 +0000 nuhil http://www.nuhil.net/?p=336 Suppose you are going to upload a big size folder containing a huge number of files on it. Think about joomla. Then if you use ftp client software such as filezilla, it will take about 2 hours if you have internet connection that has avg. speed of 15kbps.

Again if you want to delete such files or directory from that hosting place then it will take 1 hour on that speed configuration.

This is happened because filezilla checks the permission and additional facts of each file by some commands every time it uploads or deletes a file.

We will just give a single file to filzilla to upload and will make several files into a single file when deleting. Thus we can reduce the time that filzilla takes for several files.

Here we go:

First make the desired directory to be uploaded into .zip file on your pc. For example Joomla.zip

The simply upload it to the server by Filezilla. It will take no more than 15 mins in a speed of 15kbps.

Then create a php file:

<?php
  1. // Write an URL on the browser like
  2. // http://www.example.com/project/unzip.php?archive=Joomla.zip
  3.  
  4. $filename = $_GET['archive'];
  5. $zip = new ZipArchive;
  6. if ($zip-&gt;open($filename) === TRUE) {
  7.         $zip-&gt;extractTo('./');
  8.         $zip-&gt;close();
  9.         echo 'The file <strong>'.$filename.'</strong> Extracted successfully';
  10.     }    else {
  11.         echo 'failed';
  12.         }
  13. ?&gt;

Run this script on that same directory and follow the instruction above the code. It will extract that Joomla.zip into Joomla. Then Delete the Joomla.zip in a sec. Thats it.

Now guess, you have uploaded a wrong folder wasting a huge time or you need to replace that directories with your customized files and folders. Now here we talk when deleting such a big directory. We dont know how big and recursive it is.

Create this file:

<?php
  1. function removedir($dirname)
  2.     {
  3.         if (is_dir($dirname))
  4.         $dir_handle = opendir($dirname);
  5.         if (!$dir_handle)
  6.         return false;
  7.         while($file = readdir($dir_handle)) {
  8.             if ($file != "." &amp;&amp; $file != "..") {
  9.                 if (!is_dir($dirname."/".$file))
  10.                 unlink($dirname."/".$file);
  11.                 else
  12.                 {
  13.                     $a=$dirname.'/'.$file;
  14.                     removedir($a);
  15.                 }
  16.             }
  17.         }
  18.         closedir($dir_handle);
  19.         rmdir($dirname);
  20.         return true;
  21.     }
  22.  
  23. $dirname='Joomla';
  24. removedir($dirname);
  25. ?&gt;

This will delete that whole directory whether it is empty or not.

Here is a bonus function that will make a directory into a .zip file. You better know its usage. Just run it on the server and make a .zip copy of a desired directory.

<?php
  1. // increase script timeout value
  2. ini_set('max_execution_time', 300);
  3.  
  4.  // create object
  5. $zip = new ZipArchive();
  6.  
  7. // open archive
  8. if ($zip-&gt;open('file.zip', ZIPARCHIVE::CREATE) !== TRUE)
  9.  {
  10.  die ("Could not open archive");
  11.  
  12.  }
  13.  
  14. // initialize an iterator
  15. // pass it the directory to be processed
  16. $iterator = new RecursiveIteratorIterator(new RecursiveDirectoryIterator("Joomla/"));
  17.  
  18.  // iterate over the directory
  19. // add each file found to the archive
  20. foreach ($iterator as $key=&gt;$value) {
  21. $zip-&gt;addFile(realpath($key), $key) or die ("ERROR: Could not add file: $key");
  22.          }
  23. // close and save archive
  24. $zip-&gt;close();
  25. echo "Archive created successfully Named file.zip";
  26. ?&gt;

This will work just like any Ajax or Jquery form validation but it is simply Javascript and CSS.

For example when we want to make a digit or a summation of some value to a text format in the case of any accounting purpose then this code of functions will help.

  1. $nwords = array( "zero", "one", "two", "three", "four", "five", "six", "seven",
  2. "eight", "nine", "ten", "eleven", "twelve", "thirteen",

  44. } else {    //  millions

  57.  
  58. //Where should you need to have the text format
  59.  
  60. echo 'There are currently '. int_to_words(100) . ' members logged on.';

The parameter “100″ will be processed by the functions and will output a value : one hundred

You can make a Web app using Bangla Interface simply by using one kind of Unicode Font write such as
Avro Keyboard. But there is a restriction. In the client PC , the page will not be shown properly if there does not exist any bangla font installed. So, you can give a link in that page to download a font.

You can also get the benifit of MySQL using simple Queries. Define the database and table datatype as utf8_general_ci . Then in database configuration file write these two line after mysql_select_db().

mysql_query(‘SET CHARACTER SET utf8′,$con);
mysql_query(“SET SESSION collation_connection=’utf8_general_ci’”,$con); //$con is DB configuration lines

Now you can do normal PHP-MySQL tasks in your application. Here is an example named Bangla.zip in Share Box

It uses copy() for the upload method and add a random number based on time to avoid replacement of the files including same file name.

This is the approach:

The form for uploading:

  1. <table border="0" cellspacing="1" cellpadding="0" width="500" align="center" bgcolor="#cccccc">
  2. <tbody>
  3. <tr>
  4. <form id="form1" action="multiple_upload_ac.php" enctype="multipart/form-data" method="post">
  5. <td>
  6. <table border="0" cellspacing="1" cellpadding="3" width="100%" bgcolor="#ffffff">
  7. <tbody>
  8. <tr>
  9. <td><strong>multiple Files Upload </strong></td>
  10. </tr>
  11. <tr>
  12. <td>Select file
  13. <input id="ufile[]" name="ufile[]" size="50" type="file" /></td>
  14. </tr>
  15. <tr>
  16. <td>Select file
  17. <input id="ufile[]" name="ufile[]" size="50" type="file" /></td>
  18. </tr>
  19. <tr>
  20. <td>Select file
  21. <input id="ufile[]" name="ufile[]" size="50" type="file" /></td>
  22. </tr>
  23. <tr>
  24. <td align="center">
  25. <input name="Submit" type="submit" value="Upload" /></td>
  26. </tr>
  27. </tbody></table>
  28. </td>
  29. </form></tr>
  30. </tbody></table>

multi

The processor file:

“);
  1. $path1=$path1a.time().$num1.'_'.basename($_FILES['ufile']['name'][0]);
  2.  
  3. //add a random name with the base name
  4. $path2=$path2a.time().$num2.'_'.basename($_FILES['ufile']['name'][1]);
