within PHP (XAMPP) installed on a Windows XP Computer Im trying to read a dir which exists on a local network server. Im using is_dir() to check whether it is a dir that I can read.
In Windows Explorer I type \\\server\dir and that dir is being shown.
When I map a network drive a can access it with z:\dir as well.
In PHP I have that script:
<?php if( is_dir($dir){ echo 'success' } ) ?>
For $dir I tried:
/server/dir
//server/dir
\server\dir
\\server\dir
\\\\server\\dir
and
z:\dir
z:\\dir
z:/dir
z://dir
But I never get success?
Any idea?
thx
I solved it by changing some stuff in the registry of the server as explained in the last answer of this discussion:
http://bugs.php.net/bug.php?id=25805
Thanks to VolkerK and Gumbo anyway!
I love stackoverflow and their great people who help you so incredibly fast!!
EDIT (taken from php.net):
The service has limited access to network resources, such as shares
and pipes, because it has no credentials and must connect using a null
session. The following registry key contains the NullSessionPipes and
NullSessionShares values, which are used to specify the pipes and
shares to which null sessions may connect:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters
Alternatively, you could add the REG_DWORD value
RestrictNullSessAccess to the key and set it to 0 to allow all null
sessions to access all pipes and shares created on that machine.`
add RestrictNullSessAccess=0 to your registery.
You probably let xampp install apache as service and run the php scripts trough this apache. And the apache service (running as localsystem) is not allowed to access the network the way your user account is.
A service that runs in the context of the LocalSystem account inherits the security context of the SCM. The user SID is created from the SECURITY_LOCAL_SYSTEM_RID value. The account is not associated with any logged-on user account.
This has several implications:
...
* The service presents the computer's credentials to remote servers.
...
You can test this by starting the apache as console application (apache_start.bat in the xampp directory should do that) and run the script again. You can use both forward and backward slashes in the unc path. I'd suggest using //server/share since php doesn't care about / in string literals.
<?php
$uncpath = '//server/dir';
$dh = opendir($uncpath);
echo "<pre>\n";
var_dump($dh, error_get_last());
echo "\n</pre>";
Try the file: URI scheme:
file://server/dir
file:///Z:/dir
The begin is always file://. The next path segment is the server. If it’s on your local machine, leave it blank (see second example). See also File URIs in Windows.
Yes, I know this is an old post, but I still found it, and if anyone else does...
On Windows, with newer servers, verify the SMB is installed and enabled on the target machine.

I installed the Couchbase Server and its PHP SDK through brew install libcouchbase on Mac. The server admin console is running/working fine on http://127.0.0.1:8091/. I added a hello.php file with the below code in /Library/WebServer/Documents/hello.php.
<?php
$cb = #new Couchbase("http://127.0.0.1:8091/",'username','password');
if($cb->getResultCode() != COUCHBASE_SUCCESS){
throw Exception('Cannot connect to couchbase!');
} else {
echo "Hello World!";
}
When I go to http://127.0.0.1:8091/hello.php, I get an error saying Not found.. What is the problem?
When I go to http://127.0.0.1:8091/hello.php, I get the below error

You are going to the wrong port. Port 8091 is the Couchbase Server Console interface. It looks like you are trying to deploy your hello.php script using the Apache server shipped with OS X which uses the default http port (80). The script is also located in the wrong folder. I believe /Library/WebServer/Documents/ is for static content only.
Given the problem you have ran into it make me suspect that you are trying to learn too many new things at once. You should try running the script outside of a Apache first and get it working there.
php hello.php
It is also worth pointing out that you are using the older 1.X version of the Couchbase PHP SDK, you will want to use the new 2.X version.
I assume you've anonymized the code above, but be sure in place of where you have 'username' you have the bucket name and similarly for the bucket password or empty string if no password. Also, check the docs as the connect string you're using is not necessarily the preferred..
Note for debugging these kinds of things you can set LCB_LOGLEVEL to a higher level as mentioned in the documentation. The way you set an envvar varies based on how you're deploying PHP, but you can easily just test it at the command line.
Well. I read some topics in SO but I not found a very specific answer.
I need to check with PHP if a PHP code is running in local or remote host. Currently I check with $_SERVER['SERVER_NAME'] but it is inconsistent. In this case, if I run PHP with listed IPs like 127.0.0.1 or localhost it'll consider local, otherwise remote. If I share my IP with a friend, my code still local, but it consider remote because the shared IP isn't listed.
Well, I think that check IP for localhost is not a good idea (except if you know a good method). I tried methods like gethostbyaddr() and gethostbyname() but don't work correctly too.
I don't have a PHP code to show, but my code is basically that:
// true = localhost
return $_SERVER['SERVER_NAME'] === '127.0.0.1';
The fundamental question is: what can determine that PHP is running local? What is "local" for PHP? I think that it can solve the problem.
Obs.: I don't have access to CMD/Shell with PHP.
You could do what most PHP frameworks do and set a flag during your app's bootstrap phase that defines which environment the code is running in. In it's simplest form:
// the setting when run on a dev machine
define('ENV', 'local');
Then it's a simple case of:
if ( ENV == 'local' )
{
// do stuff
}
This is how I do it, which I find more reliable than trying to detect for 127.0.0.1:
if( strpos(gethostname(), '.local') !== false ) { }
Basically, the hostname's on my workstations all have .local appended to it. You can change this to match your workstation's hostname entirely.
Check $_SERVER['REMOTE_ADDR']=='127.0.0.1'. This will only be true if running locally. Be aware that this means local to the server as well. So if you have any scripts running on the server which make requests to your PHP pages, they will satisfy this condition too.
If someone is visiting your site via the web, the IP address you see will never be 127.0.0.1 (or ::1 for IPV6), regardless of the usage of a proxy. (Unless of course you're running the proxy yourself on the same server ;)
As far as I know, only you will be able to know what addresses are local or not. Your network could be set up with IP addresses that don't look local at all. PHP cannot as far as I know determine this by itself.
I'm using php 5.2 with IIS7.5.
I have a network share on a NAS that is username and password protected. I cannot disable or change authentication info on the NAS. I need to be able to access that network share via php.
I've done the following:
Created new user in windows whose username and password matches those on the NAS.
Created IIS application pool that uses this same auth info.
Created a web.config file inside of the php app directory with an impersonation turned on, using the same auth info.
identity impersonate="true" password="ThePass" userName="TheUser" />
Turned on ASP.NET impersonation in the application authentication in IIS.
None of this seemed to work with this simple line of code in php:
$dir = opendir("\\someservername\somesharename");
Warning: opendir(\someservername\somesharename) [function.opendir]: failed to open dir: No error in C:\websites\site\forum\testing.php on line 7
So, I decided to test the configuration with ASP.NET.
string[] diretories = System.IO.Directory.GetDirectories("\\someservername\somesharename");
The asp.net test worked perfectly.
Going further down the rabbit hole, I ran phpinfo() and checked the username info in it. Down in the "Environment" section of phpinfo, I found the "USERNAME" item. Its value was "TheUser," as was what I expected.
Everything points to the system being configured correctly until I tried:
echo get_current_user();
Which returned, "IUSR." That surely isn't what I expected.
So, how in the world do I get php + IIS7.5 to read from a foreign network share?
Update:
Thanks to a few of the answers, I've added
$result = shell_exec("net use o: \\\\pathToServer\\27301 /persistent:yes 2>&1");
Which returns a success. I'm still getting the error on opendir. I tried another test and used is_dir. This returned false on my newly created mapped drive.
var_dump(is_dir("o:\\"));
// Prints: bool(false)
UPDATE
I ran the script from the command line when logged in as the user that created. The scripts executes correctly. Could this take us back to get_current_user() which returns IUSR? I tryied getmypid() which returned a process ID. I cross referred that process id with the task manager and found that it was for php-cgi.exe, running under the custom user account that I made.
The recommended way to access a network share in PHP is to "mount" it. Try to connect your share as a network drive.
Btw. your command is wrong
$dir = opendir("\\someservername\somesharename");
You have to use 4 "\" because it's the escape character
$dir = opendir("\\\\someservername\somesharename");
NOTE: get_current_user() returns the owner of the process on IIS
You can try a test by mapping it like
$command = "net use $drive \"\\\\$ip\\$share\" $smb_password /user:$domain\\$smb_username";
$result = shell_exec($command);
on opendir you need to have \\\\$server_name\\$share try with 4 '\' and if mapping like that works and 4 '\' is failing on opendir. You may have credentials not matching.
If you map it this way new user you created in windows whose username and password matches those on the NAS will have rights on mapped drive that way you do not need to worry about the scope.
Had the same problem on a similar system. Solved this by going to web site > Authentication > Anonymous Authentication > Change IUSR to whatever your username is or use Application Pool user if correctly configured.
I'm making a GWT project that uses PHP to connect to a DB2 database. When I compile the project and deploy it to the server (copy the contents of the WAR directory over), it works fine, obviously in hosted mode I run into the SOP issue since GWT is on port 8888 while the php script is running on port 80.
I'm trying to get the -noserver option to work but I must be missing something.. I went back and created the basic sample app from the command line (webApplicationCreator -out /home/mike/gwt/sample1)
I edited the build.xml to include the -noserver and -port 80 arguements for devmode. I want my app to be hosted at localhost/sample1 so I edited the -startupUrl to the whole URL I want to use: http://localhost/sample1/sample1.html
I compiled (ant), copied over the sample1.html, sample1.css from war to the webserver sample1 directory, and the (md5).gwt.rpc, clear.cache.gif, sample1.nocache.js and hosted.html files from the war/sample1 to sample1/sample1 directory as described in the GWT documentation (no history.html file was created).
I then run ant devmode from the project directory (/home/mike/gwt/sample1)
I can get to the sample1.html page, but when I click the button to send the name to the server it returns with
Remote Procedure Call - Failure
Server replies:
An error occurred while attempting to contact the server. Please check your network connection and try again.
I turned on firebug and it's returning a 404 for http://localhost/sample1/sample1/greet. This is where I'm stuck.. this file obviously doesn't exist on my webserver.. but why? Isn't this something that is supposed to be getting compiled by GWT?
Can anyone give me a hand? Thanks!
So, basically you've copied over the client-side of a client/server application. When your GWT client application attempts to make a Remote Procedure Call (RPC) to the server to a greeting service that is part of the initial sample, it can't find that service.
If you wanted to copy that service over, you'd need to have a Java application server, copy over the GreetingService, the web.xml that references it and possibly a few other things (I'd have to check in more detail). That doesn't sound like what you actually want, so either you'll want to build a GWT-RPC service in PHP that responds to that URL, or remove the reference in the GWT code to RPC call to the greeting service.
With a PHP back-end, you're probably not going to use GWT-RPC, I'm guessing that you're more likely to use JSON or XML, and if that's the case, then I'd go with removing the RPC call altogether for now.
Does this all make sense? Feel free to ask for further clarification.
To solve the SOP issue, I used the HttpProxyServlet to proxy the HTTP requests to my webserver through the development server.
Download httpProxyPackage.jar, copy it into WEB-INF/lib/, and configure it like so in WEB-INF/web.xml (this is for the StockWatcher tutorial, assuming your web root is the folder that contains the StockWatcher directory):
<servlet>
<servlet-name>jsonStockData</servlet-name>
<servlet-class>com.jsos.httpproxy.HttpProxyServlet</servlet-class>
<init-param>
<param-name>host</param-name>
<param-value>http://localhost/StockWatcher/war/stockPrices.php</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>jsonStockData</servlet-name>
<!--
http://127.0.0.1:8888/stockPrices.php in dev mode
http://gwt/StockWatcher/war/stockPrices.php in prod mode
-->
<url-pattern>/stockPrices.php</url-pattern>
</servlet-mapping>
Then redefine your JSON URL as:
GWT.getHostPageBaseURL() + "stockPrices.php?q=";
instead of:
GWT.getModuleBaseURL() + "stockPrices.php?q=";
It’s maybe not the best way, but if it can get someone else started… There was another way using php-cgi, but I didn’t have it installed.
I have been trying to figure out a way to manage our domains at work and easily created a SimpleDNS class, but now I'm on the IIS Server Administration side of it and I'm just lost on what is going on.
Here is the PHP code I am running to test it.
<?php
$cmd = 'iisweb /create c:\websites\examplesite.com\www "Example Domain!" /d www.examplesite.com';
exec($cmd,$data);
print_r($data);
?>
But when I run it I get:
Array ( [0] => Error &H80041003: Access denied
I am completely stumped on how to set up permissions for this.
Here's the good part! When I run <?php exec('ping google.com',$data);?>: it works seamlessly.
I have no idea where to start when it comes to setting up the permissions for iisweb.vbs (the iisweb vbs file). I don't even know if I'm supposed to set up permissions on that file. I don't know if I'm supposed to setup a CGI option in the console. I'm lost.
Can someone help me out? What am I doing here?
Your code will be running under one of two identities.
The identity of the Application Pool that the website runs in (NETWORK SERVICE for example if the defaults were used). You can find this out by opening the property window for an application pool and selecting the Identity tab.
The identity of the website anonymous user which you can find in Website Properties -> Directory Security -> Authentication and access control (click the edit button).
FastCGI
If you're running PHP under FastCGI and the c:\php\php.ini configuration value fastcgi.impersonate = 1 then user identity be the site anonymous user (option 2) above. If fastcgi.impersonate = 0 then PHP scripts will execute under the identity of the application pool (option 1).
You can tell if PHP is configured to execute under FastCGI by looking at the .php scriptmap for the site (Website Properties -> Home Directory -> Configuration -> Application Extensions). If it's set to C:\WINDOWS\system32\inetsrv\fcgiext.dll then you're running FastCGI.
No FastCGI
If your .php script map is not configured to use C:\WINDOWS\system32\inetsrv\fcgiext.dll
then scripts will run under the identity of the site anonymous user (option 2 above).
In all cases the account used must have Administrators rights to be able to run the IIS admin scripts.
