undefined built in functions in Zend Studio 13

I have created PHP7 project in Zend Studio 13 and I get warnings like this Call to undefined function 'dba_open'. Why Zend Studio didnt recognize these functions?

dba_open
dba_close
dba_fetch
mhash

Any ideas how to solve this?

Solution

Zend doesn't ship language support for all the extensions in Zend Studio.

The most efficient way of adding support for language entities provided by unsupported extensions is definitely creating stubs. The description "stub" files for all supported PHP entities can be found in this directory: /.metadata/.plugins/org.eclipse.php.core/language And this is also the location where you should put your stub files.
