hey, guess who JUST read the readfile(); page in the manual? ;)

Down in the comments section are the following posts... I've posted them
here in case anyone is trying to solve this problem in the future and
stumbled across this thread (hello future! do you have flying cars?)

regarding php5:
i found out that there is already a disscussion @php-dev about readfile
() and fpassthru() where only exactly 2 MB will be delivered. so you may
use this on php5 to get lager files

.... which eventually morphed via 'chrisputnam at gmai<snip>' into the
following function, which i have used successfully. thanks chris!


function readfile_chunked($filename,$retbytes=true) {
$chunksize = 1*(1024*1024); // how many bytes per chunk
$buffer = '';
$cnt =0;
// $handle = fopen($filename, 'rb');
$handle = fopen($filename, 'rb');
if ($handle === false) {
return false;
}
while (!feof($handle)) {
$buffer = fread($handle, $chunksize);
echo $buffer;
ob_flush();
flush();
if ($retbytes) {
$cnt += strlen($buffer);
}
}
$status = fclose($handle);
if ($retbytes && $status) {
return $cnt; // return num. bytes delivered like readfile() does.
}
return $status;

}
