PHP Force downloding shows network error

Question

I trying to make document download using PHP force downloading and i used the below code ``` header("Content-Type: application/octet-stream"); header("Content-Transfer-Encoding: Binary"); header("Content-Length: ".filesize($path) ."\""); header("Content-Disposition: attachment; filename=\"".basename($path)."\""); header("Expires: 0"); header("Cache-Control: no-cache, must-revalidate"); header("Pragma: no-cache"); ob_clean(); flush(); readfile($path); exit; ``` But when i run the script it just shows download starting... and shows "Network error" in chrome and when i checked network console it shows something like this ``` Request URL:http://websddress.com/presse/index.php?option=com_presse&task=viewDoc&id=2578&lg=FR Request Method:GET Status Code:200 OK Request Headersview source Accept:text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8 Accept-Encoding:gzip,deflate,sdch Accept-Language:en-GB,en-US;q=0.8,en;q=0.6 Connection:keep-alive Cookie:__utma=139058359.696…

Accepted Answer

This:

```
header("Content-Length: ".filesize($path) ."\"");
```

outputs in headers this:

```
Content-Length:"
```

replace by:

```
header("Content-Length: ".filesize($path));
```

and fix the `$path` which is also not correct because it returns `null` (or `false`).

The output should be something like:

```
Content-Length: 10032219
```

Also, the correct mime-type for PDF is:

```
 Content-Type: application/pdf
```
