Which php functions are essential for adding content into file or uploading file?

Hello,

please without which php functions would be impossible to add content into file or upload an file from (computer or url) within an php script?

i wish to find which functions are essential for doing that task:
- adding new content to a file on apache, php webhosting
- uploading new file (from computer or url or from whatever)
- creating a file with content from within php script

thank You

 

Seriously? Have you even TRIED googling?

I _was_ being helpful. That page list all the different PHP functions and methods to interface with the file system. Which was what you asked for, albeit that list is more exhaustive than your specific items.

I can't help it if you're incompetent.

As for your specific list-items?
file_put_contents() will allow you to add to, or rewrite / create a file, with content.
Uploading a file involves a BIT more then just a single function, as you want to check for correct filetype, size, etc, all depending on what you're trying to do.
Uploading from your computer, or via an url are two different things entirely

 

this was much better, thanks

so first function according to your oppinion is:
file_put_contents()

 

It is one way to do it, yes. There are plenty others.
