I've not source at hand now, but this seems reasonably only a request to
define a PHP resource to be used as a transaction, so, probably, it will
be started only when actually requested in a command, or assigned to a
PHP var, as in

Seems that you misunderstand documentation: you may need to have two ore
more distinct type of transaction in the same script, so you need to
differentiate them, and only the default transaction is unnominated and
isn't needed in parameters, other must be passed in parameters.

You can do that in php.ini or use in very first statements of script

ini_set();
