very simple:

<?php
$fh=fopen("Logs/test.txt","r") or die ("can't open file");
?>


Doesn't open the file. blank screen. File is in the location.

Am i missing the big picture here?
 
you have to do more than opening the file..

Code:
<?php
$filename = "Logs/test.txt";
$fh=fopen($filename,"r") or die ("can't open file");

$contents = fread($fh, filesize($filename));
fclose($handle);

echo $contents;
?>

i got this figured...wasn't passing anything to the browser.

but....when attempting to open a PDF file...all i get is garbage. Is there a certain header that i need to be passing for this?
 
btw. wrap the entire logic in:

Code:
if (is_file($filename)) {
  // put open code here
}
else {
  echo "404 - file not found";
}

send a header with the content-type set to application/pdf and make sure the content encoding is binary.

the header function is well documented with examples in the manual
 
lol...that helps not.

was testing with other formats (xls doc etc..)....they all open as garbage
 
that's what i have currently...i still get garbage on the screen instead of the the file.
 
i'd always open the file for binary read. safer that way
Code:
$fp = fopen("test.pdf", "rb");
[/content]
 
James, are you sure the problem is not on the machine you are on?

Do you have acrobat reader installed on the webbrowser?

yes...no problem with the machine. as suggested from an earlier post...i am trying to move away from using <a href to fopen() to open my files.
 
try this

Code:
$filename="test.pdf";
$path = "path/to/file/";
header('Content-type: application/pdf');
header('Content-Disposition: attachment; filename="'.$filename.'"');
readfile($path.$filename) or die("cannot open file");

readfile is binary safe.
 
ok...it appears that standard text files and images i can open. I can't open anything else..displays garbage. Here is my code I am using:

$filename="test.doc";
$path="C:\\";

header("Cache-Control: private",false);
header('Content-Type: application/octet-stream'); // Good
header("Content-Type: image/jpeg"); // Good

header("Content-type: application/pdf"); // Garbage
header("Content-type: application/msword"); // Garbage
header("Content-type: application/vnd.ms-excel"); // Garbage

header('Content-Disposition: attachment; filename="'.$filename.'"');
header("Content-Transfer-Encoding: binary");
readfile($path.$filename) or die("cannot open file");
 
can you try adding a filesize header.
header('Content-Length: ' . filesize($path.$filename));
 
also if you specify a content type like msword, i think the disposition would be better left out or set to inline.
 
modified code:

$filename="spcc.doc";
$path="C:\\";

header("Cache-Control: private",false);
header('Content-Type: application/octet-stream');
header("Content-Type: image/jpeg");
header("Content-Type: application/pdf");
header("Content-Type: application/msword");
header("Content-Type: application/vnd.ms-excel");
//header('Content-Disposition: attachment; filename="'.$filename.'"');
header("Content-Transfer-Encoding: binary");
header('Content-Length: ' . filesize($path.$filename));
readfile($path.$filename) or die("cannot open file");
 
i tried both ways...having all in there and also commenting all but msword
