Problem with file reading

Hi,

I'm a beginner and i'm still learning PHP and I got a problem:




$file = "http://localhost/test_folder/test1.txt"; //I have also
tried "test_folder/test1.txt" and "text1.txt"


$fh = fopen($file, "r") or die("Could not open file!");


$data = fread($fh, filesize($file)) or die ("Could not read file!");


fclose($fh);


echo $data;


The file exist, I'm using apache server on my PC for practicing and the
file is located in the servers root folder on the subfolder "test_folder".

Help would be greatly appreaciated

Thanks in advance!

Is there a reason why you're trying to access it through a URL? If not,
please don't.

The file path needs to be relative to the current file. So if your PHP
file is in the root, "test_folder/test1.txt" should work. If your PHP
file is in a folder named code in the root, "../test_folder/text1.txt"
should work.

Also, depending on your PHP version you're probably better off using
file_get_contents instead of fopen/fread/fclose.

The OP referred to the "servers root folder". Now stop nit-picking and
go back to quoting standards.

Ok, let me clarify...

Using mod_php with Apache will make the current directory the directory
that contains the script being requested. I am assuming that the OP is
trying to access the file from the script that is being requested and
not an included file in a different directory - I should have been
clearer on that.

I never said anything about being relative to the document root - you
pulled that out of somewhere yourself.

Happy now?

Arent' you confusing this with something else? fopen() is affected
by the current working directory of the process calling it. What kind of
"root" are you talking about? The filesystem root, "/"?

I'm not nitpicking. If the webserver process (assuming mod_php) runs in
a different directory, fopen("relative/to/documentroot/path.txt") won't
help him at all, and as far as I can tell, it's quite common for web
servers to run with pretty much any cwd, often / or /var/empty (these
are local filesystem paths).

You're right, sorry for the noise!
