I want to check if files exists in the network folder (eg. path = "U:\abc\def\") using php.
I tried to use following:
if(file_exists("U:/abc/def/400abc.doc")) {
echo "YES";
} else {
echo "NO";
}
I get NO. I also tried path = "//abc-drive/folder-main/abc/def/400abc.doc" but still it doesn't work.
The files are on a network/shared folder and NOT in subfolders from where php server runs
Can anyone please tell HELP?
Regards
This won't work if PHP has safe_mode enabled. Try setting safe_mode_include_dir to add an exception, and reference the location with the syntax \\computername\share\filename.
Use the URI format. file://U:/abc/def/400abc.doc
Change FASTCGI Setting in server
[FASTCGI Setting] -> open ...php-cgi.ex ->
FastCGI Property -> Advanced Setting　-> protocol -> Change [NamedPipe] to [TCP].
I have same error with you, I tried it and success. GoodLuck
If file_exists is returning false for a file or folder on a Windows network drive, try the following:
Run regedit.exe
Locate the following key - HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters\RestrictNullSessAccess
Change its value from 1 to 0.
Restart your computer.
Double check your network drive is connected.
Retry your script - this time file_exists should return true.

I am wrestling with a problem. I stripped the example to this script that can be run as stand-alone application:
<?php
if(file_exists("x")){
print "<div>Deleting dir</dir>";
rmdir("x");
} else {
print "<div>Not exists</dir>";
}
clearstatcache();
mkdir("x");
If I call it repeatedly (F5 in browser) then sometimes this error occurs:
Deleting dir
Warning: mkdir(): Permission denied in F:\EclipseWorkspaces\Ramses\www\deploy\stripped_example.php on line 9
10-20 times it works OK and next time this error occurs. I googled more users has this problem but without solution.
https://github.com/getgrav/grav/issues/467
My example creates the directory in cwd, where anybody has full control. In addition the mkdir $mode parameter is ignored in windows. After the error the "x" directory truly not exists and in next attempt (F5) it is always created without error. I hopped later added "clearstatcache()" will help but nope.
In my full application I am using full file path. The deleted directory is not empty and I must clean it first. After successfull deleting the error occurs almost always.
My system is Windows 7, PHP 7.0.5, Apache 2.4
Windows doesn't let you delete things if another process is accessing them.
Check if your antivirus or some other process is opening the folder.
You can check this in resource monitor, from task manager.
Try the code with additional check on existing:
<?php
if(is_dir("x")){
print "<div>Deleting dir</dir>";
rmdir("x");
} else {
print "<div>Not exists</dir>";
}
clearstatcache();
if (!is_dir("x")) {
mkdir("x");
}
Had the same problem with Windows 10, Xampp and PHP 7. Problem was Kaspersky Internet Security, scanning and blocking the directory. Disabling KIS mkdir always works for me. Instead of directly recreating you can try rename, if disabling security software is not an option for you.
$time = time();
mkdir($path . $time);
rename($path . $time, $path);

I created a web application with a file browser. I'm trying to add a functionality where the user can change the chmod/permissions via an ajax request which is handled via PHP on the back-end.
(Side Note: I'm running my local with WAMP)
So initially, I'm reading the permissions with this
substr(sprintf('%o', fileperms($relativePath)), -4)
to get this format (0777, 0644, etc), if not it returns something like 32726. This info is used to be displayed in the UI for the user to know whats current.
However, when I run the script, I set it to 0777 and it seems to run fine. But then when I read the file again, it returns 0555 or 0444. Anyone know what I'm missing?
Does your web server own the files it is trying to change the permissions on? You can check whether chmod ran correctly or failed by testing its return value. It will return FALSE if the webserver did not have permissions. For more information you can read: http://php.net/manual/en/function.chmod.php
<?php
$is_success = chmod("myfile.pdf", 777);
if($is_sucess) {
echo "success<br />\n";
}
I realized this was not an issue, but rather the chmod command does not work properly on a windows/apache setup.
I want to create an SVN checkout PHP script. All you need is to call a function and pass two parameters: the SVN URL and the output path.
My problem is, that our SVN server can only be accessed via https. But through https, the function doesn't work. Normally the function should return a boolean, but I just get nothing. My first thought was, that I have no permission to write into the output path folder, but I changed the permission to 777 (temporarily). Still doesn't work. I also tried to get some files from another SVN trunk. Behold, this is working. I get the files. Any idea how to get this to work?
Aah, and yes, I set the svn trunk permission to read-write for everyone.
Here's is my code:
<?php
$result = svn_checkout('https://{LINK_TO_SVN_TRUNK}', dirname(__FILE__) . '/tmp');
echo "Result: ".$result;
?>
This is what I have used successfully in the past:
svn_auth_set_parameter(PHP_SVN_AUTH_PARAM_IGNORE_SSL_VERIFY_ERRORS, true);
svn_auth_set_parameter(SVN_AUTH_PARAM_DEFAULT_USERNAME, "username");
svn_auth_set_parameter(SVN_AUTH_PARAM_DEFAULT_PASSWORD, "password");
$changeLog = svn_log($path, $start_revision, $end_revision);
Please confirm if the extension is enabled. php.ini should consist of extension=svn.so or php.d folder should consist svn.ini with the line extension=svn.so. You can check for extension in phpinfo();
I can't figure out why this won't work.
$docRoot = getenv("DOCUMENT_ROOT");
include_once($docRoot."/conn/connection.php");
include_once($docRoot."/auth/user.php");
It works locally through wamp, but it won't work on my live server. I tried this:
if(!include_once($docRoot."/auth/user.php")){
session_start();
$debug = array();
$debug["docRoot"] = $docRoot;
$debug["inc_path"] = $docRoot."/auth/user.php";
$debug["file_exists"] = file_exists($debug["inc_path"]);
$_SESSION['DEBUG'] = $debug;
// exit
header("Location:debug.php");
exit();
}
The debug page just echoes that array and it shows the correct absolute paths and indicates that the file does in fact exist. So why didn't the include_once() work? The server (a DV account on a MediaTemple server) has not been configured at all, so I wonder if there is an apache or php setting that is messing with me.
Ultimately, what I want here is a way to refer to a file in such a way that if I move the file, or include it in another file, nothing will break. Any ideas?
In your debugging you might try is_readable($docRoot."/conn/connection.php"). The file_exists function will return true even if the file does not have readable permissions.
If you get an error code we might be able to provide more info as to what is going wrong.
Turn on error reporting dummy. It turns out one of the includes on another file was breaking this page and I wasn't able to trace that out until I turned on error reporting.
Incidentally, the problematic include was missing a leading slash in the filepath ( include("dir/file.ext"); ) which works on my local wamp setup and breaks on the linux server.
I'm having a critical issue where my WAMP installation for PHP 5.3.0 is not finding a file which exists within my computer. Does anyone know anything about this? Possibly a PHP Bug?
Any help would be much appreciated.
Here is the variable which creates the file:
$baseNewsUrl = "C:/reviews/reviews/$platform/$fullname";
And here is the code which grabs the contents:
if(is_file($baseNewsUrl)){
$contents = file_get_contents($baseNewsUrl);
} else {
echo "File not found. " . "\r\n";
continue;
}
Here is the output of $baseNewsUrl: C:/reviews/reviews/GBA/r20107_GBA.htm
And the file does exist.
Check that the entire path leading up to your file is readable by the user PHP is running as (if you are using IIS, this might be something like "Network Service," although I am not particularly experienced with PHP on Windows). Also, check whether the INI directives "open_basedir" or perhaps "safe_mode" are set--these would give PHP self-imposed limits on which files are accessible.
Do a var_dump (not an echo) on your variable.
var_dump($baseNewsUrl);
and look at the actual contents. You may have some invisible garbage characters in there that's preventing Windows if you're doing this in a browser to make sure there's no empty tags (or other browser-render-invisible) characters.
If that doesn't reveal anything, remove the is_file check and try to open the file with file_get_contents (or any file related function) and var_dump it's contents. You'll either open the file, or PHP will spit out an error/warning/notice (either to your browser or to your error log) that should let you know why it can't open the file.
I'm gonna say this, and it very well might not be your problem but it is a recurring one for me. If you use skype on your computer, it has a somewhat known compatibility issue with WAMP. It cause's WAMP to be unstable, not load files properly.. everything.
on windows
$baseNewsUrl = "C:\\reviews\\reviews\\$platform\\$fullname";
It's due to Windows Vista and WAMP.
