PHP open txt file and echo its contents - php

The path of my .txt file is C:\Users\George\Desktop\test.txt
And I use:
$path = "C:\\Users\\George\\Desktop\\test.txt";
$fileContent = file_get_contents($path);
echo $fileContent;
But I get file_get_contents(C:\Users\George\Desktop\test.txt) [function.file-get-contents]: failed to open stream. But why?

Use this code:
$path = "C:/Users/George/Desktop/test.txt";
$fileContent = file_get_contents($path);
echo $fileContent;

as the error mentions, that path exists...
Wrong assertion, PHP is just telling you there was an error opening that path, it doesn't mean it exists, also, the error message should mention the reason for the error, i.e.: not found, permission denied, etc...
Answer:
Your code syntax is correct. The error is one of the following 3:
1 - The file doesn't exist.
2 - The path is wrong.
3 - Php doesn't have permission to access that file.

Maybe if YOU do not have the right to read this file as PHP, the system have it, try exec or system :
$path = 'C:\\Users\\George\\Desktop\\test.txt';
function getFile_exec($path)
{
if(file_exists($path))
{
return exec("cat $path");
}
else
{
return false;
}
}
function getFile_syst($path)
{
if(file_exists($path))
{
return system("cat $path");
}
else
{
return false;
}
}
var_dump(getFile_exec($path));
var_dump(getFile_syst($path));
But as you have this error : Warning: file_get_contents(C:/Users/George/Desktop/test.txt) [function.file-get-contents]: failed to open stream: No such file or directory in /home/a2133027/public_html/index.php on line 5 and like Pedro Lobito said, you must be on linux, so, the good way to access your files on desktop may be : ~/Desktop/test.txt or ~/test.txt if it's directly in your user files ... Are you sure, you are under windows ?

Why can't php find this file?

I have an Apache/PHP site running on a Drobo5n in Linux.
utilities.php is in /Choir/inc
hitCounter.txt is in /Choir/etc/tbc
In utilities.php, we have the following line of code:
$hits = file_get_contents('../etc/tbc/hitCounter.txt');
Which produces this error:
Warning: file_get_contents(../etc/tbc/hitCounter.txt): failed to open
stream: No such file or directory in
/mnt/DroboFS/Shares/DroboApps/apache/www/Choir/inc/utilities.php
on line 6
This is my first time fiddling with PHP and I cannot figure out why it can't find the file. I've tried both single and double quotes around the path to no avail.
I know someones gonna ask for the complete code so here's the utilities.php file:
<?php
session_cache_limiter('private_no_expire');
session_start();
function getHitCount() {
$hits = file_get_contents('../etc/tbc/hitCounter.txt');
if (!isset ($_SESSION['beenHere'])) {
$hits = $hits + 1;
file_put_contents('../etc/tbc/hitCounter.txt', "$hits");
$_SESSION['beenHere'] = "Yes I have";
}
return $hits;
}
?>
1) Should explicit your file path. Hard to say in this case. We should have our root application folder.
If we follow the MVC pattern, we will get the root application folder easily.
For example https://github.com/daveh/php-mvc
I like something:
$file = APP_ROOT . '/etc/tbc/hitCounter.txt';
#APP_ROOT has the path /mnt/DroboFS/Shares/DroboApps/apache/www/Choir
2) Check file_exists
if (!file_exists($file)) {
//Throw error here
}
3) Check: is_readable
if (!is_readable($File)) {
......
}

Unable to read file in directory with file_get_contents - PHP

I have a file present in a directory content that contains a file to read from. On my MAMP installation, content/ is present in the webroot folder (/Applications/MAMP/htdocs/testApp/content). I am unable to read the file (test.txt) from the folder. The function I am using is:
function getDataFromLibrary($tgt_url) {
//header('Content-Type: text/html; charset=UTF-8');
echo "inside get data from lib.";
if(file_exists($tgt_url)) {
echo "File does exist.";
if(is_readable($tgt_url)) {
echo "file is readable.";
} else {
echo "file is not readable.";
}
} else {
echo "File does not exist.";
}
echo "tgt url = ".$tgt_url."the end.";
$file_contents = file_get_contents(urlencode($tgt_url));
if($file_contents === false) {
echo "could not read file contents.";
} else {
echo "file contents read.";
}
echo "Target url=".var_dump($tgt_url)."again the end.";
echo "File contents = ".$file_contents;
//$file_contents_replaced = str_replace($file_contents, "\"", "\\\"");
//echo $file_contents_replaced;
//var_dump($file_contents);
//return $tgt_url;
}
and the output I get when $tgt_url = content/test.txt is:
inside get data from lib.File does exist.file is readable.tgt url = content/test.txtthe end.could not read file contents.string(33) "content/test.txt" Target url=again the end.File contents =
The file does exist and is also readable. Where am I going wrong?
Any help is most welcome.
Edit:
I turned on the following errors in php.ini:
display_errors = On
and in the script, I included the lines:
error_reporting(E_ALL);
ini_set('display_errors',1);
ini_set('display_startup_errors',1);
error_reporting(-1);
The output is:
inside get data from lib.File does exist.file is readable.tgt url = content/test.txtthe end.
Warning: file_get_contents(content%2Ftest.txt): failed to open stream: No such file or directory in /Applications/MAMP/htdocs/testApp/index.php on line 323
could not read file contents.string(33) "content/test.txt" Target url=again the end.File contents =
As you check at the beginning everything $tgt_url you shouldn't after all checks change what you checked. Now you checked if file exists etc for $tgt_url and finally you wanted to get file urlencode($tgt_url) what will be not the same.
After called urlencode(), the $tgt_url will become to "content%2Ftest.txt", not "content/test.txt" again.
You can called urlencode() at the front of the getDataFromLibrary(), it will show: File does not exist.
Don't use urlencode() inside file_get_contents() functions.

move_uploaded_file() fails to open stream due to invalid argument - PHP

I have this code to move my uploaded file to a specific directory:
if (isset($_FILES["image"]["name"])){
if (!is_dir('pf/' . $uid)) {
mkdir('pf/' . $uid);
$large_image_location = "pf/" . $uid;
}else {
$large_image_location = "pf/" . $uid;
}
chmod ($large_image_location, 0777);
move_uploaded_file("$userfile_tmp", "$large_image_location/$userfile_tmp");
}
However that gives the following error:
( ! ) Warning: move_uploaded_file(pf/BfyhieniKJGGqTNm/C:\wamp\tmp\phpF08A.tmp) [function.move-uploaded-file]: failed to open stream: Invalid argument in C:\wamp\www\mingle\upload_dp.php on line 26
Any help on how to sort this out would be greatly appreciated!
This is 90% of your woes:
move_uploaded_file("$userfile_tmp", "$large_image_location/$userfile_tmp");
You using the moved to path at the beginning of the upload path. Try:
move_uploaded_file("$userfile_tmp", "$large_image_location/".$_FILES['image']['name']);
That should work better.
The error itself is pretty clear, pf/BfyhieniKJGGqTNm/C:\wamp\tmp\phpF08A.tmp is not a valid filename.
Don't change the contents of $_FILES[n]['tmp_name'] (or $userfile_tmp for that matter), since it will always contain the full path to the uploaded file.

File upload issue in host server

When try to upload a image file, hosting server makes warning sometimes. If i try uploading the same file in succeeding tries the image will be uploaded.
Warning:
Warning (2): move_uploaded_file(files/photos/3.jpg) [http://php.net/function.move-uploaded-file]: failed to open stream: Permission denied [APP/controllers/components/file_upload.php, line 55]
Warning (2): move_uploaded_file() [http://php.net/function.move-uploaded-file]: Unable to move '/tmp/phpUutr9Z' to 'files/photos/3.jpg' [APP/controllers/components/file_upload.php, line 55]
File Upload
if ( is_uploaded_file($file_temp) ) {
if (move_uploaded_file($file_temp, $destination . $filename . '.' . $extension)) {
$error = "SUCCESS";
return $error;
} else {
$error = "ERROR";
return $error;
}
}
Here when warning comes 'ERROR' in else portion is also returned with warning...
How I can correct it ?
It is working nice in local server...
Probably your script do not have permission to write to destination directory.
Check the CHMOD on the directory and on the file. Usually PHP is ran like root, but you can still forbid it's access with CHMOD.
So is APP/controllers/components/files/photos/3.jpg where you want to save your uploads? If so then its a permissions problem.
Or do you mean: WEB_ROOT/files/photos/3.jpg if so you need to change your code too:
if ( is_uploaded_file($file_temp) ) {
if (move_uploaded_file($file_temp, '/'.$destination.$filename.'.'.$extension)) {
$error = "SUCCESS";
return $error;
} else {
$error = "ERROR";
return $error;
}
}
notice the forward slash '/'.$destination

can someone help me fix my code?

I have this code I been working on but I'm having a hard time for it to work. I did one but it only works in php 5.3 and I realized my host only supports php 5.0! do I was trying to see if I could get it to work on my sever correctly, I'm just lost and tired lol
Ol, sorry stackoverflow is a new thing for me. Not sure how to think of it. As a forum or a place to post a question... hmmm, I'm sorry for being rude with my method of asking.
I was wondering i you could give me some guidance on how to properly insert directory structures with how i written this code. I wasn't sure how to tell the PHP where to upload my files and whatnot, I got some help from a friend who helped me sort out some of my bugs, but I'm still lost with dealing with the mkdir and link, unlink functions. Is this how I am suppose to refer to my diretories?
I know php 5.3 uses the _ DIR _ and php 5.0 use dirname(_ _ FILE_ _), I have tried both and I get the same errors. My files are set to 0777 for testing purposes. What could be the problem with it now wanting to write and move my uploaded file?

One way is to check from within your code whether a certain command/function is available for use. You can use the function_exists function for that eg:
if (function_exists('date_default_timezone_set'))
{
date_default_timezone_set("GMT");
}
else
{
echo 'date_default_timezone_set is not supported....';
}
Ahh! I'm sorry, didn't mean to vent my frustration on you guys. But I have been at this for hours now it seems.
Like i mentioned this code works but since my server is picky I can't user the 5.3 syntax I coded. This is my attempt to make it work on the 5.0 php my server has.
In particular I think there is something wrong with the mkdir() and the unlink() functions.
if you go to www.helixagent.com log in with test/test then in the url go to /upload2.php then you will see the errors its throwing at me.
well, it works perfect if i use 5.3 and DIR but since I'm on 5.0 i tried a different method
the errors i get are
Warning: move_uploaded_file(./uploads/saiyanz2k/images/banner/azumanga-wall.jpg) [function.move-uploaded-file]: failed to open stream: Permission denied in /services7/webpages/util/s/a/saiya.site.aplus.net/helixagent.com/public/upload2.php on line 112

It looks like you don't have access to the folder (or file)
/uploads/$username/images/banner/$filename
which could be because of a basedir restriction on the host (e.g. you may not leve the parent directory /services/webdata/) or just a missing permission in the os.
Try to (temporary) set permission of /uploads/ to 777 or execute the script from console to see if you have a basedir restriction.
Take a closer look at the paths in the error messages:
./uploads/saiyanz2k/images/banner/azumanga-wall.jpg
/services7/webpages/util/s/a/saiya.site.aplus.net/helixagent.com/public/upload2.php
The destination is a relative path, most likely relative to upload2.php's directory. The one relative path I see is the line:
// Take directory and break it down into folders
$dir = "uploads\\{$username}\\images\\banner\\thumbs";
Which should probably be:
// Take directory and break it down into folders
$dir = "\\uploads\\{$username}\\images\\banner\\thumbs";
Actually, it should be
$dir = "/uploads/{$username}/images/banner/thumbs";
since PHP supports using a forward slash as directory separator on all platforms, while the backslash is only supported on MS platforms.
