From PHP you are able to open up a file on your server and write to it. If the file does not exist we can create it, however, if the file already exists you must chmod it to 777 so it will be writable.

Oct 29, 2008 - I am trying to download a.php file from a website because I want the script that he. Thus the server only sends the generated HTML & no php. Upload the file you want to make available for download to your web server. For example, say you have a PDF file that you want people to download when they click a link. You would first upload that file to your website's hosting environment. Huge_document.pdf; Edit a new PHP file in your web editor – for ease of use, we recommend naming it.
Writing to a File
When writing to a file, the first thing you need to do is to open up the file. We do that with this code:
Now we can use the command to add data to our file. We would do this as shown below:
At the end of the file, we use fclose to close the file we have been working with. You may also notice we are using n at the end of our data strings. The n servers as a line break, like hitting the enter or return key on your keyboard.
You now have a file called YourFile.txt that contains the data:
Jane Doe
Bilbo Jones
Rewrite Data
If we were to run this very same thing again only using different data, it would erase all of our current data, and replace it with the new data. Here is an example:
The file we created, YourFile.txt, now contains this data:
John Henry
Abigail Yearwood
Adding To Data
Let's say that we don't want to rewrite over all of our data. Instead, we just want to add more names to the end of our list. We would do that by changing our $Handle line. Currently, it is set to w which means write-only, beginning of the file. If we change this to a, it will append the file. This means it will write to the end of the file. Here is an example:
This should add these two names to the end of the file, so our file now contains four names:
John Henry
Abigail Yearwood
Jane Doe
Bilbo Jones
I have disabled root login to my server. Now, I cannot use my SFTP program to download log files form my server. So, as an alternative, I have been trying to download files through the console to my local computer. RSYNC, SCP and everything else that I have tried does not work because I would have to SU to root to have permissions to the log file.
I understand that duplicating the multi GB log files and assigning different permissions would work but that't a hassle as I have limited space on this machine.
Is there a way to login, SU to root, and then put in a command that would download a file to my computer?
