Re: Re: PHP 5 limits "readfile" to 1.9 MB?

Ok, just checking (I am new to the fopen() function). That makes sense. Awesome, thanks! Jordan On Aug 17, 2005, at 10:19 AM, Catalin Trifu wrote:

    Hi,

    Indeed a fclose($fp) is needed (wrote it as an example :)).
    1MB is more than enough as a buffer.  If you have a 53MB file,

what will happen then ?

    I have no idea if it's a bug or a feature. Either way I did lose

some hair over this when I switched from PHP4 to PHP5. Catalin Jordan Miller wrote:

Catalin, Wow, that worked great, thanks. I'm curious why you set a static buffer of 1024768... why not just do filesize($file), as shown at http://www.php.net/fread ? Is it better for memory usage to have a potentially smaller buffer? Also, you may want an fclose($fp) after the file has been downloaded. So is this a bug in PHP 5 or are they just purposely limiting the abilities of the "readfile" command? Jordan On Aug 17, 2005, at 3:36 AM, Catalin Trifu wrote:

    Hi,

    I've had a similar problem. The download always stopped at  exactly 2.000.000 bytes.
    You have to work around that with:
    $fp = fopen($file, 'r');
    if($fp) {
    while(!feof($fp)) {
        echo fread($fp, 1024768);//see the huge buffer to read into
    }
    } else {
    //whatever error handler
    }

Hello all, I am new to this list and I have searched the archives to no avail. I am having a peculiar problem when upgrading to PHP 5: My downloads are now limited to the first 1.9 MB of the file in question, with the download either terminating at 1.9 MB or seemingly continuously stuck in a downloading process at 1.9 MB. The code in the PHP script has not changed and all parameters that I could find that are relevant to this problem are given below: the minimal code needed for download:

        // $file_to_read is the complete path of the file to download
        header("Content-Type: application/pdf");
        header( "Content-Disposition: inline; filename=\"$filename \"");
        $len = filesize($file_to_read);
        header("Content-Length: $len");
        @readfile($file_to_read);
php.ini file for both php version 4 and 5 contain the following   settings that may be relevant:

allow_url_fopen = On

max_execution_time = 300     ; Maximum execution time of each  script,  in seconds
max_input_time = 300    ; Maximum amount of time each script may   spend parsing request data
memory_limit = 8M      ; Maximum amount of memory a script may   consume (8MB)

post_max_size = 200M upload_max_filesize = 200M Some additional details: All files less than 1.9 MB download fine It is not a corrupted file, because all files larger than 1.9 MB fail after 1.9 MB The connection is not timing out (download of 1.9 MB takes only ~15 sec) Mac OS X 10.3.9 with Marc Liyanage's PHP 5.0.4 Fails for both Safari and Firefox Fails regardless of "inline" or "attachment" Fails regardless of "pdf" or "ppt" content-type This PHP code ALWAYS works for Marc Liyanage's PHP 4.3.4 with the same settings, above What am I doing wrong??? Any other parameter in php.ini I should have set? Any suggestions are much appreciated. thanks, Jordan
