PHP Create and Save a txt file to root directory

Question

I am trying to create and save a file to the root directory of my site, but I don't know where its creating the file as I cannot see any. And, I need the file to be overwritten every time, if possible.

Here is my code:

$content = "some text here"; $fp = fopen("myText.txt","wb"); fwrite($fp,$content); fclose($fp); 

How can I set it to save on the root?

Answer 1

It's creating the file in the same directory as your script. Try this instead.

$content = "some text here"; $fp = fopen($_SERVER['DOCUMENT_ROOT'] . "/myText.txt","wb"); fwrite($fp,$content); fclose($fp); 

Answer 2

If you are running PHP on Apache then you can use the enviroment variable called DOCUMENT_ROOT. This means that the path is dynamic, and can be moved between servers without messing about with the code.

<?php   $fileLocation = getenv("DOCUMENT_ROOT") . "/myfile.txt";   $file = fopen($fileLocation,"w");   $content = "Your text here";   fwrite($file,$content);   fclose($file); ?>
