fread() (help please)

TheStalker

ok this has got to be simple for someone that knows.

I have two sites sitting on my localhost atm within two different folders, say one folder called "site1" and another folder called "site2"

not i have workout that you can read and display the data from another php page using the fread() but how do i go about accessing a diffrent folder?

this work within the root of my site that im in

$myFile = "hello2.txt";
$fh = fopen($myFile, 'r');
$theData = fread($fh, filesize($myFile));
fclose($fh);
echo $theData;

but how do i get out and into the other site? does this make sense? i hope so.

Any help wud be good thanks 🙂

If you are just reading the file, you can use file_get_contents for that.

So if this is your directory tree:

readfile.php
site1/hello2.txt
site2/hello2.txt

You can access those from readfile.php like this:

// hello2.txt from site1 folder
echo file_get_contents('site1/hello2.txt');

// hello2.txt from site2 folder
echo file_get_contents('site2/hello2.txt');

If you meant that you need to read file from entirely different server, then you just use the full url to that text file.

hey,

thanks for your reply i will see if i can get that to work. Will that work if i only want to select parts of a php file to read and then display ?

PHP simply relies on your local filesystem to find the file based on the path, so all standard paths apply in PHP. So, if you were in 'site2' for example and wanted a file in the 'site1' folder, you could use a path such as:

../site1/file.txt

where '../' tells the filesystem to look in the "parent directory" of the directory you are currently in.

Well, [man]file_get_contents/man will read in the entire file, so it'd be up to you to discern what data you want to display.

There may be alternative ways, but that would require us knowing what your selection criteria is - what data do you want to select?

Thanks

../site1/file.txt

thats was what i was after. Tbh i havnt worked out what data im going to need to select and display, i just know its not going to be all of it.

thanks again 🙂

You're quite welcome. Don't forget to mark this thread resolved (if it is; if you want to wait and see if you can figure out how to select whatever data you're after, feel free).
