Queries server for WHO information (PHP 4 >= 4.3.3, PHP 5 <= 5.0.4)
bool ircg_who ( resource connection, string mask [, bool ops_only] )

ircg_who() will request a list of users whose nickname is matching mask on connected network connection. The optional parameter ops_only will shrink the list to server operators only.

The answer is sent to the output defined by ircg_set_file() or ircg_set_current(). 如果成功则返回 TRUE,失败则返回 FALSE
