Answer 1

Hope this will help you:

$File = "log_post.txt"; 
$fh = fopen ($File, 't') or die("can't open file");  
fclose($fh);

Answer 2

$location = fopen("input.txt", "r") or die("Unable to open file!");
echo $location;
fclose($location);

Use this code and keep the input.txt file in the same directory where this code is written.

Answer 3

First check if file exist or not?

 $filename = '/path/to/foo.txt';

if (file_exists($filename)) {
    chmod($filename, 0777);
    echo "The file $filename exists";
} else {
    echo "The file $filename does not exist";
}

Answer 4

$location = file_get_contents('./input.txt', FILE_USE_INCLUDE_PATH);
echo $location;

or

$location = file_get_contents('input.txt');
echo $location;

hope it will help

Answer 5

Add full path to file. On the Windows platform, be careful to escape any backslashes used in the path to the file, or use forward slashes.

$location = fopen("C:\\folder\\input.txt", "r");

Answer 6

Remove '/'(Slash)

$location = fopen("input.txt", "r") or die("Unable to open file!");

Answer 7

$file = fopen("path/input.txt","a+") or die("Unable to open file!");
.....
fclose($file);

You have to create file before you READ or if you open file by 'r' , so if you open file by 'a+' , your file will be created automatically.
