COPY(3) 								 1								   COPY(3)

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
Returns TRUE on success or FALSE on failure. CHANGELOG
+--------+---------------------------------------------------+ |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. See fopen(3) | | | for more details. | | | | +--------+---------------------------------------------------+ EXAMPLES
Example #1 copy(3) example <?php $file = 'example.txt'; $newfile = 'example.txt.bak'; if (!copy($file, $newfile)) { echo "failed to copy $file... "; } ?> SEE ALSO
