I don't know anything about imagemagick, I have a need to convert images that users upload to gif format and resize and optimize said images as well. Before I look further into it, can someone please clarify whether imagemagick is a software or a standalone script? Meaning do I need to have it installed on my server or can I just uload the files and use the script's commands?
I'm referring to imagemagick for PHP.
It depends what you mean by "install."
If you are talking about the PHP extensions, then yeah, those have to be "installed."
If you are talking about the standalone binary programs, then no, they don't have to be "installed." If you can find a copy of the programs designed for the exact type and version of the operating system your server runs, you could place them somewhere accessible, give them execute permissions, and call them from your script. However, some shared hosting providers prohibit you from running compiled binaries in any way whatsoever, so this might not be such a good idea.
Your best bet is going to be either convincing your hosting provider to install it, or switching providers to one that already has it installed.
try MagickStudio
To convert, edit, or compose your image directly from a Web page, press Browse to browse and select your image file or enter the URL of your image. Next, set any of the optional parameters below. Finally, press view to continue.

I have an idea that will make all Linux servers running PHP more secure.
I want to configure php.ini File Uploads to scan any new file upload with ClamAV's clamscan.
Is it possible? How should I configure it?
While there are libraries for interacting with ClamAV within PHP scripts, there is no way to automatically scan all uploaded files automatically.
Mainly, due to flexibility. For example, if you run a security website to track various viruses and store a copy of each, ClamAV would get to them during the upload, rendering your website useless. The better approach would be to do this in the client code, and use one of the libraries in the link above to perform scanning.
Having said that, I don't believe this is something that's impossible to achieve. You can write a PHP extension that hooks into fileuploads to automatically run ClamAV on uploaded files.
im trying to implement on my site a system who let the user download a file that have to be change before the download.
I have a master file (a .exe program), that inside have a variable who has to be change for every different user.
The most simple solution is to change a variable inside a xml file every time the user want his personalized exe and then make the exe file to read the external file. BUT i dont want the user to download more than one file.
Is this possible? using php can i change a parametter inside a compiled program? Thanks for any help and suggestions!
If you really really know what you're doing and you know exactly the bits that need to be flipped inside the file, then yes, it's possible to modify the .exe file with PHP. Otherwise you have to make changes to the source or other files the .exe is built with and compile the program on the server before sending it to the user.
In theory it's certainly possible (PHP is turing complete), but as stated in other answers it will be hardly worth the hassle (considering the fact that you have to ask whether it is possible shows you'd have to investigate at last for days into the standard exe-format).
I'd recommend one of the following:
1) Zip the program with the configuration file; either use a separate launcher (e.g. Java [a JAR is a ZIP file]) or add a configuration file that is read by the program itself. There is a number of PHP libraries for generating ZIP files.
2) compile the program with the changed source on the server itself; however this can also become quite complicated depending on your server configuration and the programming environment you use. If you have never administered a virtual server I would not even slightly recommend that as an option.
3) If you can assume that the user got somewhat stable Internet access you might also consider to let hir download a standard executable, where additional configuration will be downloaded later on by the program itself (e.g. by transmitting the username to the server). However this creates dependencies you might want to avoid (your user probably can't use it on machines without Internet access and you should assert that your server is up most of the time).
While it's probably possible, I doubt it's worth the hassle. Unless you're trying to fight piracy or something. Why don't you just serve the user a custom .zip file with the .exe and a config .xml?
[edit after OP commented]
I presume what you're trying to edit is the facebook ID/username? Well, try to compile the base file with some unique string like "THISNEEDSTOBEREPLACED", then use some binary safe function to replace it. Though remember things can and will get tricky if the string lengths don't match.
Hello I am wondering what processes involves converting files online...What programming languages are required?Basically I am wondering how are the files on scribd,issu,slideshare converted...
Thank you..!
There is a media processing library called FFMpeg. It will read, write and convert pretty much any common media format. It can resize, crop, scale, resample, etc all the files it can load, meaning videos can be shrunk in size, or whatever you might want to do!
The great thing is, if you have PHP and FFMpeg installed on a server, you can use PHP's exec() command to convert/modify/save videos.
A little note: beware of using exec() with any commands that are influence by what is sent from the server, like frame sizes, etc - hackers can latch onto them and mess your server up!
To get round the problem of pethetic people (script kiddies, etc), try ffmpeg-php. I don't know how popular this is on web hosts, but I haven't seen it many places in the wild.
James
EDIT
Unfortunately not. FFMpeg is primarily for video/audio conversion. However, there is a program called pdf2swf that should do the trick. The man page for it is here.
The only concern about pdf2swf is whether your web host actually has it installed on their server. If you have a VPN or a dedicated server, that's no problem, but if you're on shared hosting, and have no access to the root filesystem, this is where issues arise - you can't install pdf2swf if you don't have it.
I have developed a PHP-MySQL web application, which is a school-based project.
My client wants this application to be converted into a .exe file such that it can be installed on his desktop and use it.
How the PHP website can be converted to a .exe file and can it be run without the need of a database/server software?
Please advice.
The convenient solution is not to convert the website to .exe. I think it will be better if you have portable server/php/mysql and make the website work from a usb or CD with autorun.
NuSphere's PhpDock claims to do this: It serves as a deployment helper and comes with a bundled web server. However, I don't know about the database part, and it's not free.
PhpDock enables you to deploy any PHP web application as a Stand Alone Windows Desktop application w/o any changes in the code.
I don't know that particular product, but I have been using their IDE for years and am quite happy.
try using a site-specific browser. it will make a desktop app that is basically a portal running to your webapp. try this one:
https://mozillalabs.com/prism/
It allows alot of advanced features like system tray icons and such. I have used it many times!
Hope this helps, JL
Short answer: Not possible.
Long answer: It depends.
You could install a web- and database server on his machine (or create an installer that does it) and run the application locally on his machine.
or
You keep the application on a server and just provide a launcher that opens his browser and points it to the URL of the application.
As Artefacto mentioned, it might be a good idea to switch to SQLite instead of MySQL but depending on how your application is written it might require a lot of code and SQL Query changes.
No. You have at least to remove the dependency on MySQL (and use e.g. sqlite instead).
Then, you would either have to:
Convert the webpages to windows dialogs. This would completely change your application (e.g. what would originally be http "form submissions" would be someting completely different). At this point, it'd much easier to write a .NET application
Bundle a web server (e.g. Apache) with PHP installed.
Another try would be to turn your php project into PHP-GTK (http://gtk.php.net/).
Yet another one is to give HPHP a try (https://github.com/facebook/hiphop-php/wiki/) and try to turn the generated C code into something like a .DLL in .NET and use it for the logic while coding the UI in say, C#.
Just create a simple program in C or C++ that will just add icon in Start menu, desktop and Quickstart. If your client clicks the icon it will open the default OS browser and point it to URI of your application online.
That might fool your client :)
Or maybe it will be enough for him (he might be asking you to convert it to exe because he can't remember URI or something - ask him what is the reason).
You can use xampp open-source project to pack your PHP site into an executable file.
Use the following steps:-
1. Download Xampp source code.
Add your PHP file inside htdocs directory(Ref:- https://sourceforge.net/p/xampp/code/HEAD/tree/win32/xampp/htdocs/).
Now compile the XAMPP source code and distribute it.
For DATABASE creation and initial data loading in the database, you can code your site in such way that if database is not created, it redirects the page to install.php which do the database creation and data loading task using sql file provided(you need to add SQL file containing database structure and required data).
Don't forget to delete the SQL file post installation of database.
Not sure that's gonna be possible but have a look at:

Solution 1:
There are several solutions to convert your web application into a desktop application, the one I prefer is the open source solution: PhpDesktop, but unfortunately it only supports SQLite.
Best Solution:
To convert your PHP application with MySQL I know a paid solution that does this: 'ExeOutPut For Desktop', it is the best for this job
Php desktop is the way to go, it's actually very simple to modify to the version of PHP you want to use and is open source too https://github.com/cztomczak/phpdesktop
I have a PHP script running that lists files in a certain directory on the server. Is there any way to access the file's icon metadata? Lots of issues with this I suppose (eg: depends on the OS hosting the script. depends on whether the file is using a custom icon. still have to convert the icn file to something that can be displayed in a browser) but any suggestions are welcome. I guess I could display a different icon depending on the file extension, but it would be nice to do it automatically.
You might be able to plug into the /icons folder that most apache installations have setup for their default directory listings.
It's not OS dependent at least.
You should be able to craft a url that displays an icon for a particular extension.
GDLib or ImageMagic possibly is that what you are looking for... But if you want to access metadata GDLib won't help. Not sure about ImageMagic.
Actually, you can create thumbnails with their help and cache them somewhere to avoid performance issues.
If you want to extract IPTC information from file you can use getimagesize function fith extra parameter.
