Unable to open a file from PHP using fopen [duplicate]

Question

i am trying to read contents from a text file in php. i am using wamp on windows. i m getting this error:

Warning: fopen(/input.txt): failed to open stream: No such file or directory in C:\wamp\www\cycle_gps_sender.php on line 3

this is my code:

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

both the php file and input.txt are placed in www folder of wamp.

try to use full path of your file. if it still cannot be opened, it should be the permission problem. — Jacky Shek

Also, if the .txt file is in the same directory of your PHP file, remove the / or just do parent directories. I've had similar problems and it was cause it didn't know what the / was. Hope this helps. — Jack Hales

Hope this will help you:

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

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");

$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.

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";
}

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

or

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

Remove '/'(Slash)

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

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

//make sure that your text in the folder is name input only, not input.txt

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