PHP/YAZ keeps track of connections with targets
|
|
(Z-Associations). A resource represents a connection to a
|
|
target.

The script below demonstrates the parallel searching feature of
|
|
the API. When invoked with no arguments it prints a query form; else
|
|
(arguments are supplied) it searches the targets as given in array
|
|
<literal>host</literal>.
