Reading files

[Hessuu]

I'm a php noob trying to create a php file which can read files from my school's server. The file in which the script should be has this kind of path:

<ServerDomain>\<MyUserName>\<ProjectName>\public_html\index.php

And this is the path of the files I need to read:

<ServerDomain>\<MyUserName>\<ProjectName>\public_html\files\subfolder1\text.txt

If I place the text file in the same directory as index.php it works, but if I move it in the subfolder, it gives me this message when trying to open it in browser:

Warning: fopen(subfolder1\text.txt): failed to open stream: No such file or directory in <ServerDomain>\<MyUserName>\<ProjectName>\public_html\index.php on line 3

 

This is the code that causes this failure(it's from php.net's php documentation):

 

$myFile = "files\subfolder1\text.txt";
$fh = fopen($myFile, 'r');
$theData = fread($fh, filesize($myFile));
fclose($fh);
echo $theData;

 

Thanks for your time.

HERE you are using backward slash (\) that is considered as escape character user following code

 

$myFile = "files\\subfolder1\\test.txt";
$fh = fopen($myFile, 'r');
$theData = fread($fh, filesize($myFile));
fclose($fh);
echo $theData;

 

OR the best way to user directory separator

 

define("DS",DIRECTORY_SEPARATOR);
$myFile = "files".DS."subfolder1".DS."test.txt";
$fh = fopen($myFile, 'r');
$theData = fread($fh, filesize($myFile));
fclose($fh);
echo $theData;

fclose($fh);
echo $theData;

 

The best way would probably be to use single quotes and realpath, like:

 

$filepath = realpath('files\subfolder1\test.txt');

 

realpath modifies the directory separator to match the OS directory separator.

Thanks for the answers, now I know that.

 

But now it gives me this:

Warning: fread(): supplied argument is not a valid stream resource in /home/<SchoolUnit>/<MyUserId>/public_html/<ProjectName>/index.php on line 3

And same for the fclose.

Current code:

$myFile = realpath('subfolder1\test.txt');
$fh = fopen($myFile, r);
$theData = fread($fh, filesize($myFile));
fclose($fh);
echo $theData;
