I just want to Send a file On the web server through FTP. and what i want mainly is i have a file on which i have some code for processing this file(it will be Csv) and i want to process this code automatically after uploading through FTP.Can any body please help. i have no idea about this. is there any FTp functions which will work for this.please let me know,
Install a Grunt watch task on the server which will watch for changes in the FTP folder. It's easy to install via Node's NPM.
http://gruntjs.com
This will immediately trigger a script including PHP CLI scripts to post-process your uploaded files, and is easy to configure yet powerful in scope.

I have a PHP app, which is working fine for me, both on test system and a production system.
But another user of my app wrote me, that it creates a lot of files .nfs00000* on his system and it slows down loading of the page.
My app does not create any files on the filesystem, all datas are stored into MySQL. So I was really surprised by this. But that user removed my PHP app from his website and the problem dissappeared.
I will be honest -- I know nothing about .nfs00000* files and I was not able to google out anything reasonable about them. Can someone please try to give me explanation, what they are, why they are created and if I can do anything to avoid their creation?
Thanx, Honza
Maybe this can help:
Under linux/unix, if you remove a file that a currently running process still has open, the file isn't really removed. Once the process closes the file, the OS then removes the file handle and frees up the disk blocks. This process is complicated slightly when the file that is open and removed is on an NFS mounted filesystem. Since the process that has the file open is running on one machine (such as a workstation in your office or lab) and the files are on the file server, there has to be some way for the two machines to communicate information about this file. The way NFS does this is with the .nfsNNNN files. If you try to remove one of these file, and the file is still open, it will just reappear with a different number. So, in order to remove the file completely you must kill the process that has it open.
If you want to know what process has this file open, you can use 'lsof .nfs1234'. Note, however, this will only work on the machine where the processes that has the file open is running. So, if your process is running on one machine (eg. bobac) and you run the lsof on some other burrow machine (eg. silo or prairiedog), you won't see anything.

If your app is deleting or modifying some files it could be the cause of the problem.
I am trying to build a solution where I sync a local directory with a ftp server directory. Then the files in the local directory should be send to Jira as a specific issue.
I am trying to understand how I can make script which watches the local directory and when a new file (.pdf) and attachments is created (Look after file id) send a create command to Jira with some data from this newly created file.
Currently i have made the powershell script which reads the FTP and sync's the files to a local directory. Could the rest be made in PHP?

PHP and PowerShell are both very powerful languages with extensi9on capabilities so you can pretty much do anything you want with both of them. PHP is also available on windows, so I see no objection to writing the whole thing in php.
However, seeing that you already built something in PowerShell, i would recommend that you register the freshly downloaded files in Jira with the same script. Otherwise you would have to build the logic for detecting the changes/additions twice.
I need to write a script to upload big Files (~2GB+) to a server.
I don't think HTTP is the right way to do this so I want to use (S)FTP.
There are several tutorials about this (using cURL or ftp_connect) and I understand that i have to set several things in the php.ini.
But all this tutorials upload the file to a remote Server, what I want to do is upload it to the Server the script is running on, without having to upload the file to the Server over HTTP first.
Is this possible? If so, how would I do that?
HTTP can be the right way to upload large files. You can use resumable.js or similar library to split the file in "chunks" and then reassemble the file on the server.
If you decided not to go with HTTP and have shell access, I recommend you use rsync (with the --partial flag) which will do the heavy lifting for you.
This is the situation:
I have a LAMP server, which serves HTML, PHP, etc... Now I have remote folder, somewhere in the web, which has a directory full of PHP files, images, an MVC folder structure (CodeIgniter), etc...
Now, What I want to do is that instead of every time I want to serve those PHP files, instead of downloading them and uploaded them into my LAMP server, I want to use those PHP files directly and serve them in my LAMP server.
Again, I want the PHP files from a folder in another server, which I only have access to the direct link to each individual file, being serve in my LAMP server, so if I access my website, for instance: www.website.com/page1, gets the folder structure from the remote web server or all PHP files, and get serve within my server.
I know this sounds a little bit complicated but I'm not sure what to use... Maybe reverse proxy? Do you think I may download the files directly and constantly syncing the files? If anyone gets with a good solution I may even pay that person...
EDIT(1)
Good answers so far... but I think I did not make a good question so here it goes again:
I have access to a "list" of PHP files, and in order to get them I need to authenticate myself using oath via PHP. Once I get authenticated, I can retrieve a list of PHP, html, etc.. files, each one of them having a public URL that anyone can access. So the think is that instead of downloading all files in that repository, and serve those files, I want to be able to reuse that repository's web space and I just serve these files myself. So basically I want to be able to have symbolic links to urls, which I think is not possible, but being able to just read the files and serve the PHP logic, even though the files are elsewhere.
I'm concern about the security issues involved, but if someone could help me I will be thankful... Also if you are interested in what I'm doing I always can use a partner for this project which I intent to use it in charity, but still can pay that person.
This is not a smart thing to do. You open yourself up to potential security issues, but at a minimum, you will significantly slow your site down.
I would recommend that you simply script synchronizing the files on both servers over SSH by a script.
Edit: ManseUK's suggestion if rsync is also a good one.
If you have ftp access to the remote server, you could mount the folder using fuse, and serve as usual for apache.
Do you have the ability to mount the remote folder as an NFS volume, or perhaps with SSHFS? If those options are available, either could work for you. You'd mount the remote folder locally and tell your local web server to serve files from that path.
Not that it would be the most efficient setup in the world, but I don't know why you have all this split apart in the first place. ;)
You could write a cronjob to grab the remote file list every X minutes/hours/days then store the results locally, then write a simple script to parse those results upon request. Alternatively, you could still use an NFS or SSHFS mount to read the remote paths in real time and build whatever URL's you need.
thanks all of you for patiently answering my question "About exec() function in PHP: About exec() function in PHP", it has given me an idea of how this works and so. Lots of them pointed the syntax error, my pardon forgot to include the quotes.
Actually I have got a requirement in normal conditions the customer has the .exe file which he needs to normally run from command prompt, where he needs to include the path for the license and config files manually, so that application is valid for installation.
Now he wants a php script where he will enter the web page with his valid login details and with the click of link he should be able to run the .exe file to install the software on his machine. Including the license and config file is my job which I have been working on, on the other hand I am still not clear that this is really possible to run the .exe file on the clients machine when the script runs on the php remote server. What can be the other alternatives to accomplish this. Can anyone clear my doubts?
You cannot run anything on the client machine from a PHP script running on the server. It's impossible. What you can do is create an archive (e.g. ZIP) that contains the executable file, the license file and the configuration. Then you can offer this archive to the user as download. After extracting the archive on his machine he then would be able to execute the application.
Other possibilities to execute something on the client machine would be a Java applet or a Flash application. Those are subject to a lot of security restrictions though.
Alternative:
1.Save settings to file
2.Compact programm to archive with setting file && license
3.Download archive
PHP is on the server, the server generates HTML/JS/CSS. The PHP process ends before the web page is displayed to the user.
There's no way, and a VERY VERY good reason why this can not or will never be able to be done.
And why would you want to run an .exe file on someone's computer other than malicious reasons?
You're on the Web, sell subscription, what licensing are you talking about?
There is no way to actually execute a program on the client machine directly from PHP. The best you can hope to achieve is to provide a download for the executable file and then the client can execute it manually. You could provide an archive file with the installation executable and config/license file(s), but the client would still have to execute the file manually.
You could potentially use client-side technologies such as Flash, Java or ActiveX to accomplish this, but this is not a simple task and requires fairly intimate knowledge of the languages on which these technologies are based.
If the file was an MSI, it would be theoretically possible to allow the server to remotely install it on the client machine, however there are some barriers to this:
You need a fully fledged Windows domain for this, and both the server and client machines would have to be members of that domain. There is no way around this.
You would most likely need to know the NetBIOS name of the client machine, and there is AFAIK no 100% reliable way to determine this from PHP.
Your PHP instance would need to be running under an account that has administrative privileges in the domain. This is unlikely to be the case at the moment, and it is not a very good idea to run like this anyway.
