If you're running PHP as apache module, it will always write files as 'nobody', 'www', 'httpd', (or whatever user your webserver runs as) unless you specify a different user/group in httpd.conf, or compile apache with suexec support. However, if you run PHP as a CGI wrapper, you may setuid the PHP executable to whatever user you wish (*severe* security issues apply).

If you really want to be able to su to other user, I recommend compiling with suexec support. AFAIK, PHP can't NOT use SuEXEC if apache does.

If PHP is configured as an apache module it will act as whatever user the apache is. If apache SuEXEC's to otheruser:othergroup (e.g. Root:root), that's what PHP will write files as, because it acts as a part of apache code. I suggest you double-check your SuEXEC configuration and settings. Note: you can't su to another user within the PHP code -- it has to be an apache directive, either through, or through.htaccess. Also note: I'm not sure how it all works (if it works at all) on Win32 platforms. Check www.apache.org to see how it's done.

QlikView Extensions offer nearly unlimited possibility to extend the look, feel, behavior and functionality of QlikView. Unfortunately, most QlikView developers seem to avoid them. While many may simply not need extensions, I often get the impression that a second, more important reason is that most.

The verbal descriptions take a while to read through to get a feel for the expected results for fopen modes. TIP: If you are using fopen and fread to read HTTP or FTP or Remote Files, and experiencing some performance issues such as stalling, slowing down and otherwise, then it's time you learned a thing called cURL. Performance Comparison: 10 per minute for fopen/fread for 100 HTTP files 2000 per minute for cURL for 2000 HTTP files cURL should be used for opening HTTP and FTP files, it is EXTREMELY reliable, even when it comes to performance.

I noticed when using too many scripts at the same time to download the data from the site I was harvesting from, fopen and fread would go into deadlock. When using cURL i can open 50 windows, running 10 URL's from each window, and getting the best performance possible.

Just a Tip:). PHP will open a directory if a path with no file name is supplied. This just bit me. I was not checking the filename part of a concatenated string. For example: Will open the directory if $somefile = ' If you attempt to read using the file handle you will get the binary directory contents. I tried append mode and it errors out so does not seem to be dangerous. This is with FreeBSD 4.5 and PHP 4.3.1.

Behaves the same on 4.1.1 and PHP 4.1.2. I have not tested other version/os combinations. This is an addendum to ibetyouare at home dot com's note about Apache directory permissions.

If you are on a shared host and cannot tweak Apache's permissions directives then you might try setting the same thing in a. Jana Gana Mana Free Download A R Rahman more. htaccess file. Failing that, if you are having trouble just creating files then set the directory permissions to allow writing (for whatever directory the file is supposed to be in) and include the following before fopen(): `touch /path/to/myfile/myfile.txt`; That will usually create a new empty file that you can write to even when fopen fails.

I couldn't for the life of me get a certain php script working when i moved my server to a new Fedora 4 installation. The problem was that fopen() was failing when trying to access a file as a URL through apache -- even though it worked fine when run from the shell and even though the file was readily readable from any browser.

After trying to place blame on Apache, RedHat, and even my cat and dog, I finally ran across this bug report on Redhat's website: Basically the problem was SELinux (which I knew nothing about) -- you have to run the following command in order for SELinux to allow php to open a web file: /usr/sbin/setsebool httpd_can_network_connect=1 To make the change permanent, run it with the -P option: /usr/sbin/setsebool -P httpd_can_network_connect=1 Hope this helps others out -- it sure took me a long time to track down the problem. To overwrite a file with a new content without deleting it, and without changing the owner or access rights, it's best to not use: but instead the faster one: The reason is that truncating a file at size 0 forces the OS to deallocate all storage clusters used by the file, before you write your content which will be reallocated on disk. The second code simply overwrites the existing content where it is already located on disk, and truncates any remaining bytes that may exist (if the new content is shorter than the old content). The 'r+b' mode allows access for both read and write: the file can be kept opened after reading it and before rewriting the modified content. It' s particularly useful for files that are accessed often or have a size larger than a few kilobytes, as it saves lots of system I / O, and also limits the filesystem fragmentation if the updated file is quite large. And this method also works if the file is locked exclusively once opened ( but I would rather recommend using another empty file for locking purpose, opened with 'a+' access mode, in '/var/lock/yourapp/*' or other fast filesystems where filelocks are easily monitored and where the webserver running PHP is allowed to create and update lock files, and not forgetting to close the lock file after closing the content file ).

While adding CFLAGS='-D_FILE_OFFSET_BITS=64' immediately before calling './configure' on the PHP source will enable support for using fopen() on large files (greater than 2 GB), note that -- if such an installation of PHP is used in conjunction with Apache HTTPD [2.x], Apache will become completely unresponsive even when not serving output from a PHP application. In order to gain large file support for non-web applications while maintaining the operability of Apache, consider making two distinct PHP installations: one with the above CFLAGS specified during configuration (for non-web uses), and the other without this flag (for use with Apache).

Updated March 17, 2016: added a link to the PHP topic on the VS Code documentation center. Two weeks ago I was a speaker at the conference, where I talked about. For writing and debugging my demo PHP source code, I used Visual Studio Code.

In this blog post I’ll describe the steps for configuring VS Code for doing PHP development. For more details about how VS Code supports PHP, check out the. TL;DR • and install Visual Studio Code• Configure PHP linting in user settings• Download and install the from the Visual Studio Marketplace• Configure the PHP Debug extension for XDebug Download and install Visual Studio Code Visual Studio Code is Microsoft’s free, cross-platform lightweight code editor. While you (it’s only a 42MB download), let’s look a bit closer at what I just said • Free: indeed, VS Code is entirely free, no gotchas.• Cross-platform: VS Code is available for Windows, Linux and OS X• Lightweight code editor: as opposed to Visual Studio, VS Code is not a full-fledged IDE but a code editor. It’s a code editor with a number of powerful features you might also find in an IDE, such as intellisense, debugging and Git source control integration. And by the way, VS Code is also open source – you can contribute to the sources or submit issues in the. Once you have the installer package, set it up on your machine.

You can find the detailed instructions. You should now be able to open a command prompt and launch Visual Studio Code and start editing all files in a folder. If you open a file with the.php extension, Code will recognize this file as a PHP file.

Alternatively, you can manually change the file type through the Language Mode button at the bottom right of the editor or by pressing Ctrl+K and M keyboard sequence. PHP out-of-the-box experience VS Code supports many out of the box, and PHP is one of those languages. Note that more languages are supported through VS Code extensions in the. For PHP we provide syntax coloring, bracket matching and code snippets. As you start typing code in a PHP file, you’ll notice that you get syntax coloring, bracket matching and IntelliSense as you type.

Configure PHP linting By default, VS Code will perform PHP linting to validate your code when you save your file. To do so, it is using the php executable. As you use VS Code for the first time, you’ll get an error message that the PHP executable cannot be found. As mentioned in the message, you need to specify the path the PHP executable on your machine. This is done in the settings file (VS Code has different levels of settings files, for more details check out the ). In this case, we’ll configure the PHP settings globally for the user.

Open the user settings through the command panel: press F1 >type ‘user’ >press Enter. You will now get two JSON documents: the leftmost document are the default settings, on the right hand side you find the user settings.

In the user settings you can override the default settings. For enabling PHP linting, we have 3 settings. To configure the path to the PHP executable you specify it in the user settings file: Now you should see validation enabled for you PHP files. In the event of invalid PHP, you’ll see a red squiggly lines in your source code (in below code sample, a semi-colon is missing on line number 2). Configure debugging VS Code provides XDebug debugging support using the (kudos to Felix Becker!). First, install the extension from the VS Code command panel: press F1 >type ‘install ext’ and select ‘Install Extensions’.

Then type ‘PHP Debug’ in the search box and install the extension. You will have to restart VS Code after installing the extension to activate it. Note that this extension uses XDebug. Therefore you need to ensure that you have installed XDebug. You can download XDebug (for Windows, you should get the non-thread-safe 32-bit version). Then, update your php.ini file with the following settings. In my case, I have installed XDebug in the ext subfolder of the PHP install directory.

If you installed XDebug elsewhere, make sure that zend_extension points to the correct location. Make sure to point your webserver root to your project and each time you request a PHP file, XDebug will try to connect to port 9000 for debugging. To start debugging, and navigate to the Debugging tab in VS Code.

Then press the little gear icon to generate the launch.json file, which will allow VS Code to start the XDebug debugging session. Make sure to choose PHP as the debug environment. To start debugging you can press F5 or click the green arrow in the Debugging tab.

You can set breakpoints in your source code by selecting a line and pressing F9. If you now hit the specific web page, VS Code will break into your source code at the specified breakpoint. You’ll then get information about variables, call stack, etc. In the left hand pane. Conclusion Visual Studio Code provides great PHP language support out of the box, and with the PHP Debug extension you can now also debug your PHP code. And all this for free, and cross-platform. There are more PHP extensions in the Visual Studio Marketplace for you to try out.

Links: • VS Code extensions: • More information about PHP support in VS Code. Similar issue. I downloaded 64-bit WAMP with PHP version 5.6.25, xdebug vscode extension 1.10, Visual Studio Code 1.7.2.

Xdebug was recognized as specified in the phpinfo, I enabled logging in both xdebug and the vscode xdebug extension, I would see an error in the xdebug dll log E: Could not connect to client. 🙁 I would see connect statements in vscode console from the extension, so could see that communication from both sides was attempted. PHP would run, but was unable to set any breakpoints. I did as Lee suggested, I went back to PHP 2.4.1 xdebug instead of the PHP 2.5 xdebug recommended and things started working. Here is my zend extension info in my php.ini [xdebug] zend_extension = “D: dev wamp64 bin php php5.6.25 ext php_xdebug-2.4.1-5.6-vc11-x86_64.dll” xdebug.remote_enable = on xdebug.remote_autostart = on xdebug.remote_port=9000 xdebug.remote_host=”localhost” xdebug.max_nesting_level = 512; xdebug.remote_log = “d: dev xdebug.log” •.

Alas, no luck. After much suffering PHP is recognized, I get squigly lines. I can click Debug (the play icon), but there is no Gear icon.

And after the select Environment dialog, after selecting PHP, it ends with a fantastic nothing. No confirmation, no debug interface, no error, nothing. As always, why complicate things to the point of having a beautiful but useless Visual Code install? Why provide 99% of the way (with a debug extension and an automated extension installation), but leave the remaining 1% to trip people up? This is a computer, it can find all the info by itself.

What’s needed is a install.php file and instructions to execute it: php php.exe install.php (from a batch file?). From there on, it can find all the info it needs, edit the php.ini file, etc. And it can explain what it does.

Instructions don’t work for beginners. There is always some dependency or lefover from a previous install. There is PHP that kicks of the confusion with meaningless tags like “non-threadsafe”. We surely don’t want something not safe, right?? And then the innocent fool comes along and the instructions suddenly don’t work anymore, with no indication as to why. This is of course an example, when things go wrong, we never know why. Anyway, I have a failed install, with no indication as to why, no matter how many university degrees I might have.
