4. 7.2 scripts/coder_format/coder_format.php \file_copy()

Copies a file to a new location. This is a powerful function that in many ways performs like an advanced version of copy().

• Checks if $source and $dest are valid and readable/writable.
• Performs a file copy if $source is not equal to $dest.
• If file already exists in $dest either the call will error out, replace the file or rename the file based on the $replace parameter.

Parameters

$source A string specifying the file location of the original file.: This parameter will contain the resulting destination filename in case of success.

$dest A string containing the directory $source should be copied to.: If this value is omitted, Drupal's 'files' directory will be used.

$replace Replace behavior when the destination file already exists.:

• FILE_EXISTS_REPLACE - Replace the existing file
• FILE_EXISTS_RENAME - Append _{incrementing number} until the filename is unique
• FILE_EXISTS_ERROR - Do nothing and return FALSE.

Return value

True for success, FALSE for failure.

  // Make sure source and destination filenames are not the same, makes no sense
  // to copy it if they are. In fact copying the file will most likely result in
  // a 0 byte file. Which is bad. Real bad.

    }

    // Give everyone read access so that FTP'd users or
    // non-webserver users can see/read these files,
    // and give group write permissions so group members
    // can alter files uploaded by the webserver.
