PHP - Installation Of Linux: Should I Go With The New Default Btrfs File System?!

Sorry for posting this here, but for some reason the "create new topic" in linux subforum doesnt exist.


anyways i made a small php script that enables me to retrieve data between two dates. now am stuck on how i should copy it  or u0pload it into linux.

system tells me i need to upload to /usr/bin/libexec , i am there now but i dont have the slightest idea on how to do that.


help is much appreciated.

Thanks

I am new to Php and the linux environment.  I have written a php program which sames a file to folder using xampp in Windows but I am having a problem with the pathway using my Ubuntu server and LAMP.  My code I used in Windows was:

$fileName = "guessbook.txt";
$file = fopen ($fileName, "ab");
if(!$file)
{
    echo "ERROR! did not create the file! Exiting.<br />;
    exit();
}

This file was saved correctly using xampp into the htdoc folder and worked fine when I called it in my browser.  I tried to substitute a Linux pathway ie: /var/www/assignment2/guessbook.txt, where guessbook is in the code but still nothing.  Can someone explain how to write the correct pathway to save this file?

Thank you

Paul

Hello,

I'm trying to have my index.php to open/run another test.php file.
I'm having my own server that I play with, that I run Ubuntu on.

So the index.php are located at /var/www/ directory, but I want to run a file that are located at /testing/test.php

The final test.php is file for showing pictures, and I don't want to out all the pictures under the /var/www/ location.  It's alot  of photos.
I don't know much about php but I have been trying this:

<?php
header("Location: /var/www/testing/test.php");
    //These below are desperat old tries.
//header("Location: ./testing/test.php");
//header("Location: ../testing/test.php");
//$handle = fopen("/privat/Web_pictures/test.php", "r");
//"/testing/test.php"
// header("Location: ./test.php");   //This one actually works, but I'm still in the wrong folder (/var/www/)
echo "test "; // NN4 requires that we output something...
exit();
?>

Thankful for help!   

Hey there,

Thanks for taking the time to read my thread, well basically I'm in a bit of a dilemma. I've got a string in PHP containing the contents of a file I would like to be created and I have a method of sending the command to the remote server like so:


$Connection->exec('ps aux'); 


Now my issue is I am unaware of any file editors via command like that don't have some sort of user prompt I've scoured Google for hours searching for the best possible method for this but all the file editors aren't simply processed by one line commands and edited in that same command e.g

Create File -> Write File -> Close File

Is there no possible means of doing that via one line command?.

Here is my string I wish to be written to the file.



$RestartFile = "#!/bin/bash
export SERVER_PATH=/home/client".$Server['server_owner']."/".$Server['server_id']."
cd $SERVER_PATH
while [ true ]; do
./server".$Server['server_id']." &
done");


Thank you for your time.

This is probably an easy one, but I can't figure it out and it's pretty much not searchable.

on a linux-machine i have installed filezilla

the filezilla runs pretty well and all is ok.

now i need to have the passwd that i have stored years ago. The passprhase is stored in a plain in a file called sitemanager.xmlfile


I want to find that file and open it with a terminal command.

find . -name *.sitemanager

well i thought that this will return the file I'm looking for. Now how do I open it automatically, without typing the name?
 

	find . -name *sitemanager.xm | open

This doesn't work. It says it doesn't found the open command.


question: why it does not work on opensuse?

should i use any other command - eg the following:
 

	find . -name *xyz | xargs open

or
 

find . -name *sitemanager.xml | xargs open

or

	find . -name *.xyz -exec open {} \;

and
 

find . -name *.xyz -exec open {} \; .

any and all help will be greatly appreciate

again: what is wanted and needet is to find out the passphrase in the filezilla-configuration

I havent included the whole title as it wouldnt let me but I was wondering if someone could help me on this?

I know this is possible as torrentflux caters for this but unsure of where to start.

I dont want to allow file or directory uploads or creation in my /etc/php.ini file (this is turned off).

Yet then torrentflux allows me to link a torrent from an external source (using legal downloads of course  ) but then it uploads it on my server and creates folders on a per user basis.

How is this possible can someone give me some pointers please?

I look forward to any replies,
Jeremy.

I have this code, for an Upload Form, that works successfully renaming and moving an uploaded file to the upload/ folder. 

ok this grabs mp3 from 4shared but the download link appears as preview.mp3

how could i get it to be renamed as the original reach name like here_without_you.p3 or something else?

Code: [Select]
<?php

$file = file_get_contents("http://www.4shared.com/audio/PmMMpPFs/here_without_you.htm"); 
$body = preg_replace("/.*file[^=]*=|\&volume.*/si", "", $file);  
preg_match("/((ftp)|(http(s?))\:\/\/(([A-z0-9\?\-\:\=\;\.\@\/]+)))/is",$body, $result);  
$download_url = $result[1];  

print_r($download_url);
?>

My 1st try practice uploading file to the server and it was successful.

Now I wonder how can I set a default file name to the file that will be uploaded and overwrite the existing one.

I have tried experimenting on the code but I can't get it to work.


Here's my simple code..

edit_logo.php

Code: [Select]
<?php

<form enctype="multipart/form-data" method="post"  action="uploaded_logo.php">

<input type="hidden" name="MAX_FILE_SIZE" value="100000" />

<tr>
<td>Choose a Logo to Upload: </td>
    <td><input name="uploaded_file" type="file" /></td>
</tr>

<tr>
<td>&nbsp;</td>
    <td><input type="submit" value="Upload File" name="submit>"</td>
</tr>




</form>

?>

uploaded_logo.php
Code: [Select]
<?php

if($_FILES['uploaded_file']["type"] == "image/gif")
{

$target_path = "logo/";

$target_path = $target_path. basename($_FILES['uploaded_file']['name']);



if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $target_path))
{
echo "<span class=\"error_validation\">The Logo has been successfully changed!<br></span>";
echo "<span class=\"error_validation\">Upload Logo Again? <a href=\"edit_logo.php\">Click Here</a><br></span>";
}
else
{
echo "<span class=\"error_validation\">There was an error uploading the logo. Pls. try again.<br></span>";
echo "<span class=\"error_validation\">Upload Logo Again? <a href=\"edit_logo.php\">Click Here</a><br></span>";
}

}
else
{
echo "<span class=\"error_validation\">Invalid file format. We are only accepting image file. Pls. try again.<br></span>";
echo "<span class=\"error_validation\">Upload Logo Again? <a href=\"edit_logo.php\">Click Here</a><br></span>";
}


?>

So what the code suppose to do is.. If I upload an image file as the new logo it should have the default logo name "my_logo.gif", then it will overwrite the existing one...

Anyone?

 during lesson time we're developing php systems and our topic is virtual storage like dropbox, google drive etc. My teacher has now set the task to enable the ability to share files within the server but also restrict access within the server folder. I'm being taught MySQL however I've read a lot about PDO being better and decided to use this method to try and get a higher grade for my project although I'm having difficulty understanding how to go about it what i want to achieve is: creating file sharing capability (i.e. students can share group projects) restricting users (only those working on a particular document can view it) don't worry this is not for my own benefit I'm just trying to get a grade here, I mainly just want advice on what I need I've read quite a bit but unfortunately I'm more of a visual learner.

Hello, I'm trying to create a file in my home dir and in my etc folder but I keep getting permission denied.   I am doing this   $myFile = "/home/ng/http/uid.txt";

I have been following a tutorial to create my first php application, a file (image) uploading system. I am hoping to add it to my site, http://www.kalam1ty.com/upload.php

I have read through the code multiple times and cannot find out what is wrong. I have tried to fix this for about half an hour now and cannot seem to find where the code is wrong. It does not generate any errors and passes all of the checks that I wrote, it just does not upload the image. Nothing in the upload part of the script looks off to me, but I am a PHP newbie, and am not 100% sure.

Here is the whole page's code:

Code: [Select]
<?php
        if(isset($_FILES['image'])) {
                $errors = array();
                $allowed_ext = array('jpg', 'jpeg', 'png', 'gif');

                $file_name = $_FILES['image']['name'];
                $file_ext = strtolower(end(explode('.', $file_name )));
                $file_size = $_FILES['image']['size'];
                $file_tmp = $_FILES['image']['tmp'];

                if(in_array($file_ext, $allowed_ext) === false) {
                        $errors[] = 'Extionsion not allowed.';
                }

                if($file_size > 10485760) {
                        $errors[] = 'File too large. Must be under 10MB.';
                }

                if(empty($errors)) {
                //upload file
                if (move_uploaded_file($file_tmp, 'uploads/images'.$file_name)) {
                        echo 'File uploaded to kalam1ty.com/uploads/images/';
                }

                } else {
                        foreach ($errors as $error) {
                                echo $error, '<br>';
                        }
                }
        }
?>

HI all,

this is a strange request so bear with me. I have setup a server on my local machine, what I want to do is scrape info off the real server out on the internet in some of the pages.

I have that working using curl for different domains, but the issue is I have a 127.0.0.1 host entry for the domain in question because the local server name has to match the real server name for the application to run.

I can get the real IP using a shell ie: echo exec('nslookup example.com 1.1.1.1'); but I don't know how to get curl to use that IP or force curl to use a different name server, any ideas?

 

CURL code:

 

thanks in advance!!

 

$url = "http://example.com/index.php";


$fields = [
    'id'      => '1234'
   
];


$fields_string = http_build_query($fields);

$ch = curl_init();

curl_setopt($ch,CURLOPT_URL, $url);
curl_setopt($ch,CURLOPT_POST, true);
curl_setopt($ch,CURLOPT_POSTFIELDS, $fields_string);
curl_setopt($ch,CURLOPT_RETURNTRANSFER, true); 

$result = curl_exec($ch);
echo $result;

 

Hi Everyone, this is a very old code. I know I have to change the 'addslashes' method in this code. I also just changed the code using 'mysqli'. There are two files to upload the images to a gallery, preexport.php and export.php. The upload works up to five images. if I choose 6 or more and press add images, the browser refreshes itself and the upload won't happen. All the fields on the form clears itself and no errors shows up...can you please take a look and help me correct this problem? Here are the two files...   export.php

Im looking to use this library but if i use this sample:
<?php
// test_cairo.php
$s = new CairoImageSurface(CairoFormat::ARGB32, 400, 400);
$c = new CairoContext($s);
$c->fill();
$c->setSourceRGB(1, 0, 0);
$c->setLineWidth(50);
$c->arc(200, 200, 100, 0, 2 * M_PI);
$c->stroke();
$c->setSourceRGB(0, 0, 0.6);
$c->rectangle(0, 160, 400, 75);
$c->fill();

$s->writeToPng(dirname(__FILE__)  . '/test.png');


It dont works, seems undefined, and checking for the url that php manuals tells to visit i dont work:

http://perisama.net/cairo/

How i can install and test it? I use php 6.
