Top Forums Programming Copying a file and reading size I get always zero. Post 302985581 by hicksd8 on Friday 11th of November 2016 02:43:30 PM

Hi Don,

Yep, we're all trying to guess what's happening here and none of us have enough information to know exactly.

The OP says it's a copy operation which infers that the OP expects the source to still exist after the operation. However, 'rename' is in the code.

I was attempting to explain the OP comment that his code outputs a zero length for the destination but when he lists the file it's the correct size. Given that detail I suggested that the destination was in fact a link and not a copy, and that somehow, the process fails before the inode was populated with the allocated sectors of the file. So the destination shows length zero but the source (which the OP expects to still exist) shows the correct size.

I 'guess' that we can't 'guess' any more without more info. Really sorry that I tried only to confuse the conversation.

copy - Copies file

SYNOPSIS
bool copy (string $source, string $dest, [resource $context]) DESCRIPTION
Makes a copy of the file $source to $dest. If you wish to move a file, use the rename(3) function. PARAMETERS
o $source - Path to the source file. o $dest - The destination path. If $dest is a URL, the copy operation may fail if the wrapper does not support overwriting of existing files. Warning If the destination file already exists, it will be overwritten. o $context - A valid context resource created with stream_context_create(3). RETURN VALUES

+--------+---------------------------------------------------+ |Version | | | | | | | Description | | | | +--------+---------------------------------------------------+ | 5.3.4 | | | | | | | Changed the $context parameter to actually have | | | an effect. Previously, any $context was ignored. | | | | | 5.3.0 | | | | | | | Added context support. | | | | | 4.3.0 | | | | | | | Both $source and $dest may now be URLs if the | | | "fopen wrappers" have been enabled.
