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

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"

the filesize() function also returns the same results as GetSize() for large files.

now using these functions to get a work around. 

function dos_filesize($fn) {
    if (is_file($fn))
        return exec('FOR %A IN ("'.$fn.'") DO @ECHO %~zA');
    else
        return '0';
}

function dirSize($directory) {
    $size = 0;
    foreach(new RecursiveIteratorIterator(new RecursiveDirectoryIterator($directory)) as $file){
        $size+=dos_filesize($file);
    }
    return $size;
}

This is a duplicate of bug #27792.
Short answer is: PHP does not support large files (>= 2GB) as of yet.

Indeed, clicky!
