fopen() problem - will not open a file

[james0816]

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..

<?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:

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

As for pdf, I have no experience with it.
Looks like this german guy does:

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

 

[james0816]

lol...that helps not.

was testing with other formats (xls doc etc..)....they all open as garbage

 

[Olavxxx]

you have to stream theire content, with header, as jpadie said.

<?php
$fp = fopen("test.pdf", "r");
header("Content-type: application/pdf");
fpassthru($fp);
fclose($fp);
?>

that's what i have currently...i still get garbage on the screen instead of the the file.

 

[jpadie]

i'd always open the file for binary read. safer that way

$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?

[james0816]

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.

 

[jpadie]

try this

$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.

 

[james0816]

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");

 

[jpadie]

can you try adding a filesize header.
header('Content-Length: ' . filesize($path.$filename));

 

[jpadie]

also if you specify a content type like msword, i think the disposition would be better left out or set to inline.

 

[james0816]

sry...no luck

 

[james0816]

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");

 

[Olavxxx]

Do you set all of the content-types??
You should only set one, the one which is correct for the file.
