Have upgraded my php version from 5.6 to 7.2 but i dont see new php functions like setEncryptionName for ZipArchive class. i confirm this by echoing get_class_methods('zipArchive'). Do i need to do anything else in order to use the new set of functions the newer php version provides? Please help.
The ZipArchive class is part of the zip PECL extension for PHP
You will need version 1.14.0 is higher for the setEncryptionName() function
See changelog here: https://pecl.php.net/package/zip/1.14.0
The zip extension depends on libzip >= 1.2.0
NOTE: many Linux distributions ship an older version of libzip. You might be able to find a newer version here: https://libzip.org/packages/ Otherwise you will need to compile it yourself.
