It is a follow up question to my previous post : https://stackoverflow.com/questions/20350947/php-readfile-printing-garbage-value-on-the-screen
I am creating a PHP file and then trying to download it.
What's happening is, When I create and then download, it prints garbage value on the screen.
However, If I just download the same zip file, it works perfectly fine.
My guess is, that the zip file might not be created when it tries to download it ?
Can you please suggest me, where I am going wrong with this?

I was working on response.php file, and I wanted to open another file sample.php so I changed the path & clicked on reopen file :
As it was processing, I accidentally clicked the save code button again - since the file path now had sample.php, (the code still had response file's code in it - as the sample file's code was not loaded till now) it now saved the response file's code in sample file - and somehow it closed the tab itself! So now both the files - response.php and sample.php have the exact same code, and since the tab closed, I can't undo the change in the sample.php file 🤷‍♀️
What should I do to get my sample.php's code back?
I hope you understand my problem..
Any help would be appreciated! Thanks!
You wouldn't have any problem if you had a copy of the files on your local computer before you uploaded them on your server. As far as I know, the sample.php is gone for good.
I'm trying to serve a file for download to a user, and I'm having trouble with fpassthru. The function I'm using to download a file is:
http://pastebin.com/eXDpgUqq
Note that the file is successfully created from a blob, and is in fact the file I want the user to download. The script exits successfully, and reports no errors, but the file is not downloaded. I can't for the life of me think what's wrong.
EDIT: I removed the error suppression from fopen(), but it still reports no error. Somehow the data in the output buffer is never being told to be downloaded by the browser.
I tried your code (without the blob part), and it worked fine. I can download a binary file. Based on my experience, here are something to check:
Has the file been completely saved before you initiate the reading? Check the return value of file_put_contents.
How large is the file? fpassthru reads the whole file into memory. If the file is too large, memory might be insufficient. Please refer to http://board.phpbuilder.com/showthread.php?10330609-RESOLVED-php-driven-file-download-using-fpassthru for more information.
Instead of downloading the file to local server (reading the whole file into server’s memory, and letting the client download the file from the server), you can create an SAS URL, and simply redirect the browser to the URL. Azure will take care of download automatically. You many want to refer to http://blogs.msdn.com/b/azureossds/archive/2015/05/12/generating-shared-access-signature-sas-using-php.aspx for a sample.
I was able to download the file by passing a stream obtained with the Azure API directly to fpassthru, without creating a file. Unfortunately, I can't show the code because it belongs to a project that I have finished working on and the code is no longer available to me.
My mailserver writes to a file every minute, this is fine and I'm happy for it to do that.
However on my WebServer, I want to check if that file is currently being written to and if it isn't, show the user a download link.
Is there any way I can do this..
For example: run a loop that will keep looking until the file is no longer being written to then, show a download link to the file?
I've read about flock() but I don't think this will help as another process / os is actually creating the file!
Your writting script/app/process should write lock file (empty file like filename.lock before it starts writting to main file, and then it shall remove when done. It's regular locking approach but the your script will just need to check if filename.lock is present or not. If it is, then file is being written to.
You can only acquire a read or write lock if no-one else is currently writing. You shouldn't have to do this.
Also, when the user downloads the file it could be the file has changed in the mean time. Are you sure you've got the right mental image of what you want?
