Hey guys,
Someone had asked about how to "output an mp3 file"...
> readfile(), depending on your PHP version, is going to suck in the whole
MP3 before it starts spewing out bytes.
I have had this function in my library for quite some time now, can't
remember where I got it but it's proven very useful if you want to have a
user download a large file without giving a direct link to the file. This
function will only use up 1K of memory no matter how big the file is.
Enjoy!
function readfile_chunked($filename,$retbytes=true) {
$chunksize = 1*(1024*1024); // how many bytes per chunk
$buffer = '';
$cnt =0;
$handle = fopen($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;
}
