PHP - Simple Question About Zipping Files Using Php
Hello, I never dealt with such a feature before but I found a small script online that I am editing that works just fine. The problem is that it includes all of the directories in the path of my site in the zip. So if the path of my webhost is:
/home/bob/files/ the zip will create a folder such as /home (inside that folder) /bob (inside that folder) /files (then the zipped files I wanted). I just want the zip files and I did store them out of the www/public_html directory to prevent people from downloading the files directly from the web but is there no way to make it not include all of those directories in the zip and only show the files? If so I will post the code that I have. Thanks Similar TutorialsHello Everyone, I seem to have stumbled upon something that looks like it is next to impossible in PHP; zipping files/folders on demand in php :p So, after doing some extensive google searching, I have found various functions; some work only zipping files, other have no comments, some just don't work at all, etc. After looking at multiple projects, I have finally compiled something that works and has some sort of comments on what the heck is going on. Code: [Select] <?php class zipfile { /** * Array to store compressed data * * @var array $datasec */ var $datasec = array(); /** * Central directory * * @var array $ctrl_dir */ var $ctrl_dir = array(); /** * End of central directory record * * @var string $eof_ctrl_dir */ var $eof_ctrl_dir = "\x50\x4b\x05\x06\x00\x00\x00\x00"; /** * Last offset position * * @var integer $old_offset */ var $old_offset = 0; /** * Add a directory * * @var string $name */ function add_dir($name) { $name = str_replace("", "/", $name); $fr = "\x50\x4b\x03\x04"; $fr .= "\x0a\x00"; $fr .= "\x00\x00"; $fr .= "\x00\x00"; $fr .= "\x00\x00\x00\x00"; $fr .= pack("V",0); $fr .= pack("V",0); $fr .= pack("V",0); $fr .= pack("v", strlen($name) ); $fr .= pack("v", 0 ); $fr .= $name; $fr .= pack("V", 0); $fr .= pack("V", 0); $fr .= pack("V", 0); $this -> datasec[] = $fr; $new_offset = strlen(implode("", $this->datasec)); $cdrec = "\x50\x4b\x01\x02"; $cdrec .="\x00\x00"; $cdrec .="\x0a\x00"; $cdrec .="\x00\x00"; $cdrec .="\x00\x00"; $cdrec .="\x00\x00\x00\x00"; $cdrec .= pack("V",0); $cdrec .= pack("V",0); $cdrec .= pack("V",0); $cdrec .= pack("v", strlen($name) ); $cdrec .= pack("v", 0 ); $cdrec .= pack("v", 0 ); $cdrec .= pack("v", 0 ); $cdrec .= pack("v", 0 ); $cdrec .= pack("V", 16 ); $cdrec .= pack("V", $this -> old_offset ); $cdrec .= $name; $this -> ctrl_dir[] = $cdrec; $this -> old_offset = $new_offset; } /** * Converts an Unix timestamp to a four byte DOS date and time format (date * in high two bytes, time in low two bytes allowing magnitude comparison). * * @param integer the current Unix timestamp * * @return integer the current date in a four byte DOS format * * @access private */ function unix2DosTime($unixtime = 0) { $timearray = ($unixtime == 0) ? getdate() : getdate($unixtime); if ($timearray['year'] < 1980) { $timearray['year'] = 1980; $timearray['mon'] = 1; $timearray['mday'] = 1; $timearray['hours'] = 0; $timearray['minutes'] = 0; $timearray['seconds'] = 0; } // end if return (($timearray['year'] - 1980) << 25) | ($timearray['mon'] << 21) | ($timearray['mday'] << 16) | ($timearray['hours'] << 11) | ($timearray['minutes'] << 5) | ($timearray['seconds'] >> 1); } // end of the 'unix2DosTime()' method /** * Adds "file" to archive * * @param string file contents * @param string name of the file in the archive (may contains the path) * * @access public */ function add_file($data, $name) { // Read the file $fp = fopen($data,"r"); $data = fread($fp,filesize($data)); fclose($fp); // Clean the file name $name = str_replace("", "/", $name); $dtime = dechex($this->unix2DosTime(0)); $hexdtime = '\x' . $dtime[6] . $dtime[7] .

On a Mac, this works with the stuffit program, but the default archive program does not like the zips if it contains a directory. If you comment out $zipTest->add_dir("images/");, the archive will work great on a Mac as well. Could someone help me get this class to create a working directory on a Mac as well? I am at a point where I would be willing to pay for your time if you can help me get this working (via paypal of course). Thanks in advance! weeee I'm trying to find a way to back up an entire servers file through PHP. I have a script that can take selected files into a zip file but I'm not sure how to make sure that when I loop through directory and files that I get every single file. I was thinking of just foreach(glob('*') as $file up to 10 times but I'm hoping there's something more definite then that method... Thanks Hi guys, i have an array of data, with customers and their pics. something like: Quote array (customerid=>customerpic,...........); something like Quote 123412=>'https://mylink.com/mypic343545.tiff' 433453=>'https://mylink.com/mypic3434345.tiff' my goal is to: 1. go through the array and download all the pics, with names like customerid.tiff 2. when done renaming, make a zip file ON-THE-FLY 3. download the zip file to my PC. i know i can use file_put_contents and things like that, but i am not able to really connect the dots, especially the zipping of them all on the fly.....anyone has an idea on this? I have an xml file thats about 20MB, I want to parse it all into an array. SimpleXML seems to have trouble processing it, I just get "Fatal error: Balloc() failed to allocate memory". I've googled this topic and can't seem to find a straight forward solution. There must be someone here who has had to do this before. Is there an easy way to parse this? I made this for my site and decided to share with the community. Depending on how you do the code and where, this can keep count of the views in different ways. Please read the somewhat directions have in the code, make a folder called counters, and be sure to include this below function file. I named the function file index.php and belongs in the counters folder you make. <?php /* name this file index.php and place it into a folder called counters the function will create a unique text file for each unique item, good for posts or pages and store all the files in the counters folder For the total website views,add this to your header file or top of your page <?php include('counters/index.php'); $website_view_url = "http://".$_SERVER['HTTP_HOST']; } $website_views = getViews("$website_view_url"); echo "<br />".$website_views."<br />"; ?> For the total pages or scripts views,add this to your header file or top of your page <?php include('counters/index.php'); $total_page_view_url = "http://".$_SERVER['HTTP_HOST'].$_SERVER['SCRIPT_NAME']; } $total_page_views = getViews("$total_page_view_url"); echo "<br />".$total_page_views."<br />"; ?> For entire urls including queries,add this to your header file or top of your page <?php include('counters/index.php'); $page_queries_view_url = "http://".$_SERVER['HTTP_HOST'].$_SERVER['SCRIPT_NAME']; if (!empty($_SERVER["QUERY_STRING"])) { $page_queries_view_url .= "?".$_SERVER['QUERY_STRING']; } $page_queries_views = getViews("$page_queries_view_url"); echo "<br />".$page_views."<br />"; ?> for usage in posts like by id: if do not want the pages counted and did not do the above code,include the below somewhere near the beginning of your page <?php include('counters/index.php');?> Then in the posts loop, you can associate your $row['id']; or some other unique value <?php $post_views = $row['id']; $post_views = getViews("$post_views"); echo "<br />Post Views ".$post_views."<br />"; ?> if would like to combine any the above or use them all, just be sure to just include include('counters/index.php'); only one time */ function getViews($views_count_value) { $views_count_value = md5("$views_count_value"); $views_count_file_name = "counters/$views_count_value.txt"; if (!file_exists($views_count_file_name)) { $views_count =0; $file_handle = fopen($views_count_file_name, 'w') or die("can't open file"); fwrite($file_handle, "$views_count"); fclose($file_handle); } $file_handle = fopen($views_count_file_name, "r"); $views_count = fread($file_handle, filesize("$views_count_file_name")); fclose($file_handle); if ($views_count <= 0){ $views_count =1; } else { ++$views_count; } $file_handle = fopen($views_count_file_name, "w+"); fwrite($file_handle, "$views_count"); fclose($file_handle); return("$views_count"); } ?> Hello I have the following code from php websites
$myfile = fopen("/config.php", "a+") or die("Unable to open file!");

$txt = "Mickey Mouse\n";
fwrite($myfile, $txt);
}
inside config.php is
<?php

?>
How can I replace files with another value? any help would be great thanks.
In my system I have a collection of php files which handle the requests from my ajax e.g. I have a function which lets users "subscribe" to another user's posts "userConnect()" and another function which lets a user uprate another user's post "uprate()" At the moment the uprate() function uses ajax to pass it's data to a file called "ajax_uprate.php" and the userConnect() function similarly passes it's data to a file called "ajax_userConnect.php". Would I be better to combine these files into one global ajax.php file or is it better to keep them seperate? Basically I am wondering because at the moment I have a tonne of ajax_XXX files for every single function, each containing a very small amount of code. My thinking was that the smaller these files are the faster these ajax processes would take place. Am I right in thinking this or not? Please delete my other post as I realized it is not what I needed and I cannot delete it myself. Here is exactly what I need. I have X amount of text files (with random names) in each text file there is Y amount of lines with one word on each line. I need to open all X amount of files and take the first line from each and save it in a new txt doc. then take the second line of each and save them to a new text doc. and so on. so I have all the line 1's from all the txt files together and all the line 2's together etc. I hope that makes sense. i am trying to make a page to upload music to my website and add the information of the songs into a database, but i cannot get php to let me upload a file bigger than 2mb even after i went into the php.ini and changed the max_upload_size and a few others to 99mb. So i was wondering if i could put my music in a folder on my website and pull the data from the items in the folder and make database entries(probably doubtful) or if i could get some help with getting php to upload bigger files? thanks, Adam I'm a little confused with the use of absolute paths in PHP. I've always used relative paths but it's becoming an issue with some of the apps I'm working with and absolute would solve the problem. The thing is, I'm getting different results in different places and I'm a little confused. With regular HTML I seem to be able to use / as the root of my site. So if I do the following... Code: [Select] <img src="/images/name.jpg" /> That works fine no matter what page it's called from in the site and no matter what directory that page is in. I need to be able to do that same thing with PHP. Now, in my custom 404 page I have the following... Code: [Select] if($AddressURL == 'http://www.domain.com/blog/files/filename.zip') { header('HTTP/1.1 301 Moved Permanently'); header('Location: /download/filename.zip'); exit(); } That actually works just fine. If I go to the /blog/files/filename.zip (which doesn't exist) in a web browser it winds up downloading the file at www.domain.com/download/filename.zip as expected. Now where I get confused is that include files don't seem to work like that with PHP. If I do this... Code: [Select] require_once('/includes/config.php'); That winds up looking for an /includes folder all the way back at the local server root, not just the web root. so it's looking for /var/includes instead of /var/www/includes and of course that doesn't end up working. So, how come the include file paths work differently than regular HTML paths or header redirects in PHP? Is there any simple way I can always refer to the SITE root no matter what server it's running from? I've tried playing with $_SERVER['DOCUMENT_ROOT'] but it only seems to return the root of the current document, not the root of the whole site. So if I use it within a php file located in /var/www/includes/test.php it considers /includes the root which is not what I want. Any information would be greatly appreciated. Thanks! So say i have this: Code: [Select] <link rel="stylesheet" media="all" type="text/css" href="_css/styles.css" /> now the file that is linking to that is 3 directories deep, besides using a rel or absolute link, could i define the path by using something like this Code: [Select] <link rel="stylesheet" href="<?php require($_SERVER['DOCUMENT_ROOT'] . "/_css/portfolio-styles.css"); ?>" type="text/css" /> but this is actually opening the CSS in the header thanks for any explanation on how to do this This may sound like a very stupid question, but I can't find a clear answer anywhere. I'm making my first dive in OOP and all the tutorials only really show basic usage. They define a class, and show how to use it in a file. My question is how does it work to use an object throughout a program? Is it available everywhere or do I store things in sessions and start a new object on each page? For example: logging in a user. If I created an instance after confirming the credentials, would that same instance be available for use in say index.php, or would I just pass a session over and create a new instance on each page? Again, sorry if this seems dumb to some people. I can't figure out why im getting an error with this code. if ($notif = mysql_query("SELECT * FROM notifications_1 WHERE recieverid='". $_SESSION['id']."' ORDER BY read ASC, id DESC") or die (mysql_error())); { Code: [Select] You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'read ASC, id DESC' at line 1 Hey! I have a drop down field for my "register" form, but this is clearly easy to edit, I just used tamperdata for firefox and yeah...pretty easy, is there any way that you could prevent tampering with the values when submitting this form!? Hi, I'm working on a product page and I got it to list all the products in one column of a table, but when I add a second column it just duplicates the first column. What do I need to change?

I am a new user and I have a simple question. How do I set a password for a user to log in to my site with PHP? I have no MySQL database just a iOS code/host app. I know this isn’t secure but only me and my friends are on the site. Any help is appreciated. I've seen this, Code: [Select] <?php } ?> in a lot of scripts at the very end of the script. What does this piece of code do? what does the # symbol do in php(e.x index.php?cat=1#privacy)? How can i use it? From what i 've seen you use it for changing a whole div without reloading the page like tabs.. Hello to everyone I would like to ask for this simple question.. Im trying to put if and else condition on my php code. However this condition is not working.. Code: [Select] if($file == #3#){ echo "No results found"; }else{ echo "results has been found"; } This variable $file is the result after i used an API.. If the API does not see any results they would return #3# as the result. This means they returned a transaction code of 3 which you can see here http://developer.textapp.net/WebService/TransactionCodes.aspx means that there was nothing to return. The condition does not function well even if i make 3 or #3# as part of the condition. Can you help me guys? thanks |
