when I use the Kod in my Raspberry Pi II(OS is base in debian),I found that when the size of files whick more than 2GB,the files size are incorrect.then I fixed this problem with follow mathod:
/lib/function/file.function.php
turn :
function get_filesize($path){
@$ret = abs(sprintf("%u",filesize($path)));
return (int)$ret;
}
to this:
function get_filesize($path){
@$ret = abs(sprintf("%u",filesize($path)));
return $ret;
}
but, when files size over 4G,It's still incorrect.
then add a function "fsize()" before "get_filesize()":
function fsize($file) {
// filesize will only return the lower 32 bits of
// the file's size! Make it unsigned.
$fmod = filesize($file);
if ($fmod < 0) $fmod += 2.0 * (PHP_INT_MAX + 1);
// find the upper 32 bits
$i = 0;
$myfile = fopen($file, "r");
// feof has undefined behaviour for big files.
// after we hit the eof with fseek,
// fread may not be able to detect the eof,
// but it also can't read bytes, so use it as an
// indicator.
while (strlen(fread($myfile, 1)) === 1) {
fseek($myfile, PHP_INT_MAX, SEEK_CUR);
$i++;
}
fclose($myfile);
// $i is a multiplier for PHP_INT_MAX byte blocks.
// return to the last multiple of 4, as filesize has modulo of 4 GB (lower 32 bits)
if ($i % 2 == 1) $i--;
// add the lower 32 bit to our PHP_INT_MAX multiplier
return ((float)($i) * (PHP_INT_MAX + 1)) + $fmod;
}
and turn get_filesize() to this:
function get_filesize($path){
@$ret = fsize($path);
return $ret;
}
