function advagg_file_copy

Copies a file to a new location.

Paramètres

$source: Either a string specifying the file location of the original file or an object containing a 'filepath' property. This parameter is passed by reference and 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.

file_copy()

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.
