readfile() function limited to < 2mb files?

[ageex]

hi guys,

i have download script that must use readfile() function.
But its only can download max 2mb portion of a file (pdf in my case). Is there any limitation setting for downloadding files? i cant found any directive in php.ini about this. Please help.

try adding
ini_set('max_execution_time', 0);
at the top of the script, and try using [man]file_get_contents[/man] instead of readfile. tests have been done and it seems readfile fails more often than file_get_contents.

hi,
i did this ini_set('max_execution_time', 0) directly in php.ini, but its doesn't work with readfile() neither with file_get_contents(). Tha last function give me 0kb sized result. But thanks anyway, any other ideas? 🙂

here is the codes :

$filename = "/home/website/ageex/public_html/docs/documentation.pdf";
header("Content-type: application/octet-stream"); 
header("Content-Disposition: attachment; filename=documentation.pdf"); 
header("Cache-Control: public"); 

readfile($filename);

hi,
i tried to replace readfile() function using the following codes and it works well :

$fp = fopen($filename, "r");
$buffer = '';
while(!feof($fp)){
	$buffer = fgets($fp,3000000);	
	echo $buffer;
}

but still a question why readfile() function cannot readfile > 2mb.. :bemused:

ive seen a lot of threads where people say readfile fails a lot or cant output full files properly. also on php.net there are some comments of people saying its slower than other methods too. im not sure what the reasons are, but i always stay away from readfile myself.
