Just confirming that I have also tested this using the code in the
example page as linked to below and here are the results
<?php
$iterator = new DirectoryIterator(dirname(__FILE__));
foreach ($iterator as $fileinfo) {
if ($fileinfo->isFile()) {
echo $fileinfo->getFilename() . " " . $fileinfo->getSize() .
"\n";
}
}
?>
on the same file, this returns a result of "-79538816"

just realised I typed the wrong function name in the description by
mistake. it should read "When using GetSize()" not "When using
GetFile()"

Description:
------------
When using GetFile() as documented
http://php.net/manual/en/directoryiterator.getsize.php if you run the
function on a large file you get negative values which are wrong. I
haven't got the exact file size that this happens at, but I have tested
with files of 7GB and over, and always get the same result. tested using
the function in the test script.
Test script:
---------------
function dirSize($directory) {
$size = 0;
foreach(new RecursiveIteratorIterator(new
RecursiveDirectoryIterator($directory)) as $file){
$size+=$file->getSize();
}
return $size;
}
Then ran function using input value of a directory with a single file of
8,510,398,464 bytes in size.
Expected result:
----------------
8310936 KB
Actual result:
--------------
-77674.63
