Base64 + gzinflate compressed (encrypted) files are usually CODE:

If ('php' = $ type & is_file ($ filename) & is_writable ($ filename) {// compress the code if the php file is writable.
$ Contents = file_get_contents ($ filename); // checks whether the file has been encoded.
$ Pos = strpos ($ contents, '/* Protected by grass name http://www.crazyi.cnCryptation */');
If (false ===$ pos | $ pos> 100) {// remove php file comments and white spaces to reduce file size
$ Contents = php_strip_whitespace ($ filename );
// Remove the PHP header and tail identifiers
$ HeaderPos = strpos ($ contents ,' $ FooterPos = strrpos ($ contents, '?> ');
$ Contents = substr ($ contents, $ headerPos + 5, $ footerPos-$ headerPos );

$ Encode =' ";
Return file_put_contents ($ filename, $ encode );

Return false;

// Call a function
