I have this code snippet:
<?php
$fh = fopen(__DIR__.'/foo', "w");
fwrite($fh, 'one');
rename(__DIR__ . '/foo', __DIR__ . '/bar');
fwrite($fh, 'two');
echo file_get_contents(__DIR__ . '/bar');
Output when I run this with php-7.1.26-nts-Win32-VC14-x64:
Warning: rename(C:\test/foo,C:\test/bar): The process cannot access the file because it is being used by another process. (code: 32) in C:\test\test.php on line 5

I think the responsible code is here and here, but I can't identify a change that might be responsible for this behavior.

I am doing a PHP script migration from php 5.6.40 (Apache 2.2.15 CentOS 6.10 server) to php 8.0.1 (Apache 2.4.37 CentOS 8.3).
I have troubles with fopen() function which throws a warning according to the mode option.
I searched the web without finding similar problem...
On each server, I have the same context and the same permissions :
$ pwd
/export/php/logs/aita
$ ll
-rw-r--r--. 1 apache apache 33 27 janv. 15:30 testFopen.txt
My test-script is very simple, it cheks all fopen modes :
<?php
$handle = fopen("/export/php/logs/aita/testFopen.txt", 'r'); // line 2
$handle = fopen("/export/php/logs/aita/testFopen.txt", 'r+'); // line 3
$handle = fopen("/export/php/logs/aita/testFopen.txt", 'w'); // line 4
$handle = fopen("/export/php/logs/aita/testFopen.txt", 'w+'); // line 5
$handle = fopen("/export/php/logs/aita/testFopen.txt", 'a'); // line 6
$handle = fopen("/export/php/logs/aita/testFopen.txt", 'a+'); // line 7
$handle = fopen("/export/php/logs/aita/testFopen.txt", 'x'); // line 8
$handle = fopen("/export/php/logs/aita/testFopen.txt", 'x+'); // line 9
$handle = fopen("/export/php/logs/aita/testFopen.txt", 'c'); // line 10
$handle = fopen("/export/php/logs/aita/testFopen.txt", 'c+'); // line 11
When running this script, I obtain :
On my old server PHP 5.6.40
[error] [client x.x.x.x] PHP Warning: fopen(/export/php/logs/aita/testFopen.txt): failed to open stream: File exists in /export/html/aita_dev/testFopen.php on line 8
[error] [client x.x.x.x] PHP Warning: fopen(/export/php/logs/aita/testFopen.txt): failed to open stream: File exists in /export/html/aita_dev/testFopen.php on line 9
Thoses warnings are logicals (file exists and exclusion).
On my new server PHP 8.0.1
[proxy_fcgi:error] [pid 37251:tid xxxx] [client x.x.x.x:x] AH01071: Got error '

PHP message: PHP Warning: fopen(/export/php/logs/aita/testFopen.txt): Failed to open stream: Permission denied in /var/www/html/aita_dev/testFopen.php on line 11'
Warnings from lines 8 and 9 make sense here too.
Modes r+, w[+] and c[+] generate the "permission denied" warning.
Modes r, a[+] works well, without warnings.
I am able to read the file with "r" option.
I am able to write the file with "a" and "a+" options so it doesn't seem like a permission problem.
I would like to understand and not have to correct all the fopen() of my applications...
The administrator in charge of the servers has lowered the alert level of SELinux (Security-Enhanced Linux) and everything is now functioning normally.
The system was set up to only allow read/append on files for the Apache user as suggested by IMSoP

When including files that are in the same directory or to several levels higher or lower than the current file, use the __DIR__ constant to get the path to these files.
If header.php and footer.php are in the same directory as index.php, use this code:
include_once(__DIR__ . "/header.php");
include_once(__DIR__ . "/footer.php");
If they are in a subdirectory, e.g. includes then use the code:
include_once(__DIR__ . "/includes/header.php");
include_once(__DIR__ . "/includes/footer.php");
However, if they were in another place, you use such code:
include_once(__DIR__ . "/../../includes/another.php");
The __DIR__ contains the name of the current directory where the php file is located in which the constant is used.
I need help solving , what says to be a permission error in the htdocs folder, because i needed to alter them to even add folders in the first place.
This is my init.php file:
<?php
//Start Session
session_start();
//Include Configuration
require_once('config/config.php');
//Helper Function Files
require_once('helpers/system_helper.php');
require_once('helpers/format_helper.php');
require_once('helpers/db_helper.php');
//Autoload Classes
function __autoload($class_name){
require_once('libraries/'.$class_name . '.php');
}
?>
I try to include it via `
When i run my index.php file i get this error:
Warning: require_once(../../htdocs/PHP-Wizard/helpers/system_helper.php): failed to open stream: Permission denied in /opt/lampp/htdocs/PHP-Wizard/core/init.php on line 9
Fatal error: require_once(): Failed opening required '../../htdocs/PHP-Wizard/helpers/system_helper.php' (include_path='.:/opt/lampp/lib/php') in /opt/lampp/htdocs/PHP-Wizard/core/init.php on line 9
I tried going one folder up with ../ , but it doesn't work.
I looked around for a similar error to mine, but no luck. They all say No such file or directory in (path).
Could it be that it is the same error, or do i really need to change my permissions, if so, how can i do that?
Edit: When i use include_once('helpers/system_helper.php'); i get this error:
Warning: include_once(helpers/system_helper.php): failed to open stream: Permission denied in /opt/lampp/htdocs/PHP-Wizard/core/init.php on line 9

The problem was indeed the permissions, i'm guessing because i copied the folder.
I fixed it by chmod 777 on all the files in that folder, and now it works fine.
Thank you for your time attempting to help me.
I tested using relative paths and it works fine.
<?php
require_once '../test.php';
echo ' you';
Where test.php just contains echo "hello"; resulted in the expected "hello you".
I would guess your problem is with file permissions. Can you check what permissions are on your system_helper.php? It should be at least executable by the user php is running as (usually www-data). I could reproduce your error message by doing a chown root test.php and chmod 600 test.php so I would guess something like
chown www-data: system_helper.php
or
chmod g+rwx system_helper.php
should give you permission to run the script.
I have the following Warnings which SHOULD be there, but is there a way to stop them writting to the page without actually disabling Warnings globally?

PHP Function:
//Check if the connection file is present on each drive
function scanDrives() {

$letters = "DEFGHIJKLMNOP";
$letters = str_split($letters);
$code = md5("FMbHSBTMTXhu3TWp");
//Check for a certain file on each device
foreach($letters as $x) {
$file = file_get_contents($x.":/connected.txt"); //This is what causes the error as the file can't be found.
if ($file != false) {
$file_code = split(":", $file);

Thanks.
Don't just blindly open the file with file_get_contents. Check to see if it exists first.
if(file_exists($x.":/connected.txt")){
$file = file_get_contents($x.":/connected.txt");
// ...
}
I agree with #Rocket Hazmat,
but to answer your question - in PHP you can use Error Control operators .. Specifically you can use the # sign to ignore errors.
Simple Example
$file = #file_get_contents("file_doesnt_exist.php"); // wont throw any errors.
Try to put "#" before the function that gives you the warning!

I have a problem with a php code.
Folder name what-counter This folder contains a file with the following php code named counter.php also the hitcount.txt file.
<?php
$filename = '../what-counter/hitcount.txt';
$handle = fopen($filename, 'r');
$hits = trim(fgets($handle)) + 1;
fclose($handle);
$handle = fopen($filename, 'w');
fwrite($handle, $hits);
fclose($handle);
// Uncomment the next line (remove //) to display the number of hits on your page.
echo $hits;
?>
The following php code is used in root directory files also in files from folders which echo's the hits.
<?php include("../what-counter/counter.php"); ?>
The problem
The code works in the files in folders but not in the files that are directly in the root directory.
Example: index.php is in the root directory
Using this code i get this Warning
<?php include("what-counter/counter.php"); ?>
Warning: fopen(../what-counter/hitcount.txt) [function.fopen]: failed to open stream: No such file or directory in /home/what/public_html/what-counter/counter.php on line 4
Warning: fgets(): supplied argument is not a valid stream resource in /home/what/public_html/what-counter/counter.php on line 5
Warning: fclose(): supplied argument is not a valid stream resource in /home/what/public_html/what-counter/counter.php on line 6
Warning: fopen(../what-counter/hitcount.txt) [function.fopen]: failed to open stream: No such file or directory in /home/what/public_html/what-counter/counter.php on line 8

Warning: fclose(): supplied argument is not a valid stream resource in /home/what/public_html/what-counter/counter.php on line 10
And using this code i get this Warning
<?php include("../what-counter/counter.php"); ?>
Warning: include(../what-counter/counter.php) [function.include]: failed to open stream: No such file or directory in /home/what/public_html/include/footer.php on line 31

/include/footer.php on line 31
What can i do to the $filename url and <?php include("../what-counter/counter.php"); ?> to get it to work in files in root directory as well as folders?
Either:
Include relative the the file: __DIR__.'/../somefile';/__DIR__.'/somepath/somefile';
Include relative to a known dir: $_SERVER['DOCUMENT_ROOT'] is often used, as is a PROJECT_DIR-like define() in your bootstrap code.
Change the working directory to a known/static dir chdir('/some/dir');. Not recommended as calling code may not expect this.
Sounds like absolute vs relative file problems...
Try replacing:
$filename = '../what-counter/hitcount.txt';
With, depending on where the file is located exactly, either of:
$filename = __DIR__ . '/what-counter/hitcount.txt';
$filename = dirname(__DIR__) . '/what-counter/hitcount.txt';
Or (if you're on an old php install) either of:
$filename = dirname(__FILE__) . '/what-counter/hitcount.txt';
$filename = dirname(dirname(__FILE__)) . '/what-counter/hitcount.txt';
