copy

bool copy(string from, string to) 

Copies a file.

Returns:

TRUE on success; FALSE on failure

Description:

Makes a copy of the specified file. Depends on file permissions—if the user your script runs as is not allowed to access the file and/or directories required to copy the file, the call fails.

Warning:

3.0.10, 3.0.11: Seems to have problems copying uploaded files (reported for Windows NT SP4).

Example:

Create a backup copy of a file

$file = "file"; $file_new = $file . ".backup"; if (!copy($file, $file_new)) { echo ("Could not create a backup copy of the file"); }
