PHP x86 How to get filesize of > 2 GB file without external program? -

i need file size of file on 2 gb in size. (testing on 4.6 gb file). there way without external program?

current status:

• filesize(), stat() , fseek() fails
• fread() , feof() works

there possibility file size reading file content (extremely slow!).

$size = (float) 0; $chunksize = 1024 * 1024; while (!feof($fp)) {     fread($fp, $chunksize);     $size += (float) $chunksize; } return $size; 

i know how on 64-bit platforms (using fseek($fp, 0, seek_end) , ftell()), need solution 32-bit platform.

---

solution: i've started open-source project this.

big file tools

big file tools collection of hacks needed manipulate files on 2 gb in php (even on 32-bit systems).

here's method used in soloadmin (an old freebsd-licensed project).

it first attempts use platform-appropriate shell command (windows shell substitution modifiers or *nix/mac stat command). if fails, tries com (if on windows), , falls filesize().

the original function can found here: index.php: line 1866 (svn)

i have posted modified version here, edited remove dependencies on other project-specific functions.

function filesize64($file) {     static $iswin;     if (!isset($iswin)) {         $iswin = (strtoupper(substr(php_os, 0, 3)) == 'win');     }      static $exec_works;     if (!isset($exec_works)) {         $exec_works = (function_exists('exec') && !ini_get('safe_mode') && @exec('echo exec') == 'exec');     }      // try shell command     if ($exec_works) {         $cmd = ($iswin) ? "for %f in (\"$file\") @echo %~zf" : "stat -c%s \"$file\"";         @exec($cmd, $output);         if (is_array($output) && ctype_digit($size = trim(implode("\n", $output)))) {             return $size;         }     }      // try windows com interface     if ($iswin && class_exists("com")) {         try {             $fsobj = new com('scripting.filesystemobject');             $f = $fsobj->getfile( realpath($file) );             $size = $f->size;         } catch (exception $e) {             $size = null;         }         if (ctype_digit($size)) {             return $size;         }     }      // if else fails     return filesize($file); }
