Top Forums Programming Copying a file and reading size I get always zero. Post 302985540 by hicksd8 on Friday 11th of November 2016 04:52:30 AM

As Don says, it's not possible to determine what this code is actually doing. However, it occurs to me that, it could be simply creating a link (and leaving the original file in-situ). If you then stat the link (inode) location you will likely get a zero length. However, when you list that link it will show the original file size.

However, please answer Don's questions and post what OS you are using.

lstat - Gives information about a file or symbolic link

SYNOPSIS
array lstat (string $filename) DESCRIPTION
Gathers the statistics of the file or symbolic link named by $filename. PARAMETERS
o $filename - Path to a file or a symbolic link. RETURN VALUES
See the manual page for stat(3) for information on the structure of the array that lstat(3) returns. This function is identical to the stat(3) function except that if the $filename parameter is a symbolic link, the status of the symbolic link is returned, not the status of the file pointed to by the symbolic link. EXAMPLES
Example #1 Comparison of stat(3) and lstat(3) <?php symlink('uploads.php', 'uploads'); // Contrast information for uploads.php and uploads array_diff(stat('uploads'), lstat('uploads')); ?> The above example will output something similar to: Information that differs between the two files. Array ( [ino] => 97236376 [mode] => 33188 [size] => 34 [atime] => 1223580003 [mtime] => 1223581848 [ctime] => 1223581848 [blocks] => 8 ) ERRORS
/EXCEPTIONS Upon failure, an E_WARNING is emitted. NOTES
Note The results of this function are cached. See clearstatcache(3) for more details. Tip As of PHP 5.0.0, this function can also be used with some URL wrappers. Refer to "Supported Protocols and Wrappers" to determine which wrappers support stat(3) family of functionality. SEE ALSO
