Question

I’d like to pass a filename through a GET request to a php script. I would have thought the following code:

<?php

$myFile = $_GET['filename'];

$file = fopen($myFile, "r");

while (!feof($myFile))
{
   $currentLine = fgets($myFile);
   print $currentLine;
}

?>

would work, but it is not. I’m getting the following message repeated an infinite amount of times:

Warning: feof() expects parameter 1 to be resource, string given in /Library/WebServer/Documents/maps/getFile.php on line 7

Warning: fgets() expects parameter 1 to be resource, string given in /Library/WebServer/Documents/maps/getFile.php on line 9

I know I should be wrapping my open and while loop around an IF statement to prevent the possible opening of files that do not exist, but the file I am sending EXISTS. It seems like I cannot do this with a GET request?

Answer 1

You need to use $file as the parameter for feof() and fgets(). $file represents your file handle resource. $myFile is just a string with your file name.
