Ok tx And you mean that I can concatenate every chunck in the same file ? And what about decryption, could I take the same way ? david Le Thu, 14 Jul 2005 14:25:48 +0200, Ahmed Saad <myanywhere@gmail.com> a écrit:

So I need to know a way to be able to encrypt large file.

        return false;
} while (!feof($handle)) {
    $buffer = fread( $handle, $chunksize );
// do whatever with the chuck you read.
    // you can encrypt it and write all the chunks to the same file
    // (open a file for writing before the loop)
