Trying to write a file to a different directory using fopen()

Question

I'm trying to write a file from one directory to another. For example, http://www.xxxxxxx.com/admin/upload.php to http://www.xxxxxxx.com/posts/filename.php

I've read that I cannot write a file by using the HTTP path, how do I use a local path?

$ourFileName = "http://www.xxxxxxxx.com/articles/".$thefile.".php";
$ourFileHandle = fopen($ourFileName, 'w') or die("can't open file");

Answer 1

You should use the absolute or relative path to the file on the file system.

<?php

$absolute_path = '/full/path/to/filename.php';
$relative_path = '../posts/filename.php';

// use one of $absolute_path or $relative_path in fopen()

?>
