I've found two tools which create "simlinks" within Windows XP (I know they're not real links, but so it goes). The problem is that neither of them create something which I can use with WAMP.
Because I'll often want to link into a repository, I'll often want to keep the www folder contain mostly simlinks. I'd like to do the same under Windows but while Apache recognizes what this tool creates, I get the message: Fatal error: Unknown: Failed opening required 'C:/wamp/www/cwa/something.php' (include_path='.;C:\wamp\bin\php\PHP53~1.0\pear;C:\wamp\Zend\library') in Unknown on line 0 from PHP and C:/wamp/www/cwa/ is also not recognized as a directory by PHP either. (C:\wamp\www\cwa is supposed to be the link, BTW)
How do I fix this? This tool doesn't seem to create something which is recognized by Apache. Is there another tool which is recognized by both Apache and PHP? Is this some form of ini or conf issue?
edit
The two tools above are at these two links:http://www.rekenwonder.com/linkmagic.htmhttp://www.taranfx.com/create-symlink-in-windows
Try making a hard link instead of a junction point. You can use the fsutil command. See here.
I'm just going to mark this one as "answered" because there doesn't seem to be a word-around or, if there is, no one here has shared it.
The only other viable option is to use Apache's aliasing. I had hoped to avoid that because I prefer to modify conf's and htaccess as little as possible, but it looks like there isn't a choice here.
If you are willing to use to work with PHP then it recognizes the junction points however there is an odd caching behavior that seems to occur.

I'm trying to write a website in PHP that allows the user to enter PHP code, and then be able to run it on my server. However, I want to be able to disable certain features (file access, database access, etc.). Basically, I want the code to run without any risk to my server, and if the code does attempt to do something dangerous, I just want the code to stop running (I don't mind if it just stops, produces an error, or carries on while ignoring the dangerous code).
Is this possible, and if so, how could I achieve this?
Thanks :)
It is possible using libraries that do some simple checking or limiting.
Take a look at a PECL (PHP Extensions) extension called RunKit_Sandbox http://php.net/manual/en/runkit.sandbox.php or PHPSandbox.
The key to look for on Google is PHP Sandbox, it will find you similar libraries.
vi php.ini
and then find disable_functions,
disable the functions as you want! like this :
disable_functions = exec,passthru,popen,proc_open,shell_exec,system,phpinfo,assert,chroot,getcwd,scandir,delete,rmdir,rename,chgrp,chmod,chown,copy,mkdir,file,file_get_contents,fputs,fwrite,dir
I actually developed a package specifically for these kinds of use cases. It can be fully configured and even used to override dangerous functions and globals.

I have a problem with Drupal 6.20.
Possibly after a PHP update, site stopped working. I get:
Notice: unserialize() [function.unserialize]: Error at offset 0 of 22765 bytes in /PATH/includes/cache.inc on line 33
This is the line:
$cache->data = unserialize($cache->data);
I would appreciate any help.
This problem will happen when you have Drupal 6.x running over PostgreSQL 9.0 because the bytea type was modified.
There are some suggested solutions here: http://postgresql.1045698.n5.nabble.com/Bytea-error-in-PostgreSQL-9-0-td3304087.html - (liking to Wayback Machine)
Running this on the database should fix it:
ALTER DATABASE databasename SET bytea_output='escape';
Sounds like your Drupal cache has gotten corrupted.
The immediate solution would be to clear the caches. Three ways to clear the Drupal caches:
Log in to the site with the admin password and select the flush caches option from the menu. This will obviously only be possible if you can get into the site in the first place.
If you can't do that, you can use the Drush command-line utility to flush the cashes without having to go to the site.
If you can't even get Drush to work (or you just don't want to install it), you can do it manually by going to the the database in your favourite MySQL tool, and emptying all the tables whose names start with the word "cache_".
The real question is why this would have happened in the first place. Sadly, I can't answer that, without a lot more info about your set up (and likely spending some time investigating too).
The danger is that even once you've cleared your cache, the same error could occur again, so even if you do get it working again, it would be a good idea to dig around a bit and see if you can find out the root cause.
My guess would be a rouge module that's got a bug has written bad data to the cache. You might want to check the drupal site and Google to check the modules you're using to see if there's any that have had similar behaviour reported.
Also, you mention a PHP update: Please let us know which versions of PHP you went from and to. There are known issues with some Drupal 6 modules in PHP 5.3, although the core does support it. See http://drupal.org/requirements for more info.
Try a var_dump($cache->data). It could be that PHP is adding escape sequences and/or quotes due to magic quotes or similar.
It is probably because of bad data inside of your array, you can fix it like this:
$data= preg_replace('!s:(\d+):"(.*?)";!se', "'s:'.strlen('$2').':\"$2\";'", $cache->data );
$s_data= unserialize($data);
I am new to joomla and I need to work on a joomla website for a school project. I modified an existing module to make it display featured projects and it does that flawlessly when I test the site locally. However, when I uploaded my files to the hosted copy of the website, the module will load but does not display anything. It just loads the title and the area for the php output but there is nothing returned by the script. Why would this be happening? I have joomla mostly figured out but I'm stumped when it comes to this problem.
As far as I can tell, all files related to this module have been copied over successfully and it is setup properly in the module manager. I turned on debugging mode on the hosted copy and got this message when trying to load another page with this module on it:
Parse error: syntax error, unexpected
T_STRING in
/home/content/s/r/s/srsgdmnet/html/components/com_rbids/rbids.html.php
on line 1
I looked at the file and I don't have a clue what it's talking about. Line one is just "<?php" which is fine. Is it just saying line 1 but actually referring to a problem elsewhere? This file is part of a reverse auctions component that my module interacts with. I didn't modify the code in that file with the exception of using a regular expression (search using "\n\s*(\n)", replace with "\n") to remove excessive amounts of whitespace via the replace command in Netbeans. This cut roughly 3200 lines from the file, making it much easier to navigate. I assume this did not alter anything in terms of code because it still works fine when used locally.
I modified my local configuration.php file to use the same database as the hosted copy to see if it was a database issue but it still worked fine so that rules that out. The php.ini files are the same on both copies with the exception of the local one having the Zend stuff commented out so I could use Xdebug (made this change after the problem occurred in an attempt to locate it). I have stepped through the code with Xdebug and haven't been able to track the issue down so I'm thinking it's a configuration problem.
My local copy also does not load certain modules (main menu, for one) and I can't navigate to some of the other pages, not sure if that is related. The code is the same for both copies yet each one has different results. Am I skipping vital steps for migrating the code?
I am using Joomla version 1.5.9. Please help!
Your question is ten days old, so perhaps you solved it already. But my suggestion would be to check the code for forward and back slashes. It might be that the code uses \ which works locally but fails on your server where it needs /. In Joomla extensions you can replace folder separations by DS, in the way of 'folder'.DS.'subfolder' instead of 'folder/subfolder'. The API will replace the DS by \ or / as appropriate.
However, the parse error you get indicates that something is missing in the syntax of your code. You will just have to go over it with a magnifyer glass. Sometimes when the error refers to the first line the impact of something missing works its way back to the beginning of the file. It could be a ' or ; or something small like that.
Regardless of your module, you should update to Joomla version 1.5.15 which at present is the latest version. you are 6 security releases behind schedule!
The group I have been working with has come to the conclusion that somehow Netbeans is messing up some of the files when we edit and save them. We tested by taking files from our server, opening and then saving in Netbeans, and then uploading back to the server. Sometimes this produced files that apparently did not have any newlines in them and led to php errors, breaking components or even taking down the whole site.
Our current workaround for this is to just take the files this happens to and use notepad++ to make our changes before uploading. It's a very strange issue and caused us a lot of grief. Hopefully the Netbeans team fixes this in future releases.
Thank you all for your attempts to help me solve this problem.
Try closing your <?php the traditional way and see if it works or the error line changes.
I remember seeing a similar question either on Joomla or Fabrik forums but cannot remember precise answer
I'm not much of a programmer, PHP is where I'm comfortable. And sometimes I find that I need to do things, such as arrange files or rename files on a mass scale on my computer. And I think I could do this with PHP but I can't of course.
So I was curious, is there a way I could run PHP files as kind of exe files.
EDIT: Fairly important point, using Windows.
just use php.exe (put it in your path) and the name of the php file you want to execute
You should have a look at php gtk
It's not as bad as you put it. PHP may be a very good tool for string related stuff like parsing, renaming etc. Especially if you know PHP.
To use php as script you should add #!/path/to/php as first line and set execution permissions on unixoid systems. In windows you can simply assign the php file ending with your php cli exe so you can click on them or use the script with the "start" command in the windows shell. But make sure that you write your scripts in a way that it is sensible to the current working directory. It may be different to what you might expect sometimes.
to be able to execute php files with double click, just like normal programs, go to the command line, then type
ftype php_script "C:\path\to\php.exe" "%1"
assoc .php=php_script
Check out WinBinder
Sure, just add #!/path/to/php to the top of the file, add the code in tags, and run it as a shell script.
Works fine - the php binary you use is either the cgi one or the purpose built CLI version.
http://www.php-cli.com/
http://php.net/manual/en/features.commandline.php
it would appear so, yes.
Download Wamp Server, install it. Once thats done, add the path to the php.exe to your PATH settings. You can do this by going to control panel->system->change settings->advanced->environment variables. Edit the PATH, add a ';' to the end of the line and then past the path to the php.exe. This is on Vista, it might be different on XP or Windows 7.
My path looks like this after: C:\Sun\SDK\jdk\bin;C:\wamp\bin\php\php5.3.0
Once thats done, you'll be able to execute a php file from the command line. You could create shortcuts too.

I used php for years as a scripting language before I even bothered to use it as a web programming language.
maybe php is not the right tool to doing this and it's about time to learn another language...use this chance to expand your programming horizion
See the .reg file in this gist, it makes it possible to use .php files exactly like .bat files, e.g. my_script.php foo bar baz
Don't forget to edit paths to suit your setup.
http://www.appcelerator.com/products/download/ Still use html & css as a desktop app and now has support for php.
PHP based web apps like Wordpress and Mediawiki I think uses php to setup and configure itself. Just give IIS proper read/write rights and you can make a simple web app that does massive renaming, etc.. PHP doesn't have to always be used for writing out html.
See ExeOutput for PHP. It has excellent customization and MAGNIFICENT features. Yet it is not an IDE or something. It compiles your PHP+HTML into fully-fledged EXEs.
I am calling a PHP-Script belonging to a MySQL/PHP web application using FF3. I run XAMPP on localhost. All I get is this:
Connection Interrupted
The connection to the server was reset while the page was loading.
The network link was interrupted while negotiating a connection. Please try again.
There are a number of possible solutions ... depends on the "why" ... so it ends up being a bit of trial and error. On a fresh install, that's tricky to determine. But, if you made a recent "major" change that's a place to start looking - like modifying virtual hosts or adding/enabling XDebug.
Here's a list of things I've used/done/tried in the past
check for infinite loops ... in particular looping through a SQL fetch result which works 99% of the time except the 1% it doesn't. In one case, I was using the results of two previous queries as the upper and lower bounds of a for loop ... and occasionally got a upper bound of a UINT max ... har har har (vomit)
copying the ./php/libmysql.dll to the windows/system32 directory (Particularly if you see Parent: child process exited with status 3221225477 -- Restarting in your log files ... check out: http://www.java-samples.com/showtutorial.php?tutorialid=1050)
if you modify PHP's error_reporting at runtime ... in certain circumstances this can cause PHP to degenerate into an unstable state if, say, in your PHP code you modify the superglobals or fiddle around with other deep and personal background system variables (Nah, who would ever do such evil hackery? ahem)
if you convert your MySQL to something other than MyISAM or mysqli
There is a known bug with MySQL related to MyISAM, the UTF8 character set and indexes (http://bugs.mysql.com/bug.php?id=4541)
Solution is to use InnoDB dialect (eg sql set GLOBAL storage_engine='InnoDb';)
Doing that changes how new tables are created ... which might slightly alter the way results are returned to a fetch statement ... leading to an infinite loop, a malformed dataset, etc. (although this change should not hang the database itself)
Other helpful items are to ramp up the debug reporting for PHP and apache in their config files and restart the servers. The log files sometimes give a clue as to at least where the problem might reside. If it happens after your page content was finished it's more likely in the php settings. If it's during page construction, check your PHP code. Etc. etc.
Hope the above laundry list helps somebody someday ... probably myself when I run into it again and come back here looking for "how the heck did I fix it last time?" ... :)
It's possible that your script could be caught in an infinite loop. If that doesn't apply, then I'd check the error logs like TimB suggested.
It sounds like the PHP script you're calling is failing without returning a valid response. Depending on the level of logging that you have set up, this should generate an error in the Apache logfile, which will give you some idea of the problem. I'm not familiar with XAMPP, but you should be able to find out where the logs are, and look for an error that occurred at the time you made your request to the PHP script.
copying libmysql.dll to apache\bin folder may help you overcome this strange error
I solved this problem Upgrading the xampp\php\ext\xdebug\php_xdebug.dll
(changed to php xdebug v.2.0.5-5.3-vc9 )
I had the same problem and this is what i did.
I issued the http get command through php cli script, and as it turns out I had declared one class twice somewhere.
By the way , i use AMPPS on an mac
Hope this helps some one!
Try doing the request with Firebug enabled and see what info you can get out of that; I always find that using wget is helpful for seeing the raw HTTP interaction without worrying about Firefox's UI elements interfering.
If you are using certificates for ssl in Windows 2008 Server(iis 7) from old selfssl tool(iis 6), that is the problem. Sometimes Microsoft releases patches which can destruct all these old certificates. The solution is to generate them again.
copying libmysql.dll to apache\bin folder may help you overcome this strange error
Indeed this helped me to solve this problem
The connection to the server was reset while the page was loading.
Incase the issue is not working this did the trick for me.
1. I got a new zip directory for PHP and connected it with apache
2. I searched for the libmysql in the new php and inserted this to the apache/bin
its this libmysql.dll that is needed there and not the one form mySQL/bin.
ok at least thats the one that worked.
I experienced a very similar issue - which doesn't apply to the person who asked this question - but may be of help to others who are reading this page...
I had an issue where in certain cases PHP 5.4 + eAccelerator = connection reset. There was no error output in any log files, and it only happened on certain URLs, which made it difficult to diagnose. Turns out it only happened for certain PHP code / certain PHP files, and was due to some incompatibilities with specific PHP code and eAccelerator. Easiest solution was to disable eAccelerator for that specific site, by adding the following to .htaccess file
php_flag eaccelerator.enable 0
php_flag eaccelerator.optimizer 0
(or equivalent lines in php.ini):
eaccelerator.enable="0"
eaccelerator.optimizer="0"
