<url> ::= CUBRID:<host>:<db_name>:<db_user>:<db_password>:[?<properties>]
<properties> ::= <property> [&<property>]
<properties> ::= alhosts=<alternative_hosts>[ &rctime=<time>]
<properties> ::= login_timeout=<milli_sec>
<properties> ::= query_timeout=<milli_sec>
<properties> ::= disconnect_on_query_timeout=true|false

<time> := SECOND
<milli_sec> := MILLI SECOND
- host : A host name or IP address of the master database
- db_name : A name of the database
- db_user : A name of the database user
- db_password : A database user password
-
alhosts : Specifies the broker information of the standby server, which is
used for failover when it is impossible to connect to the active server.
You can specify multiple brokers for failover, and the connection to the brokers
is attempted in the order listed in alhosts
-
rctime : An interval between the attempts to connect to the active broker in
which failure occurred. After a failure occurs, the system connects to the
broker specified by althosts (failover), terminates the transaction, and then
attempts to connect to the active broker of the master database at every rctime.
The default value is 600 seconds.
-
login_timeout : Timeout value (unit: msec.) for database login. The default
value is 0, which means infinite postponement.
-
query_timeout : Timeout value (unit: msec.) for query request. Upon timeout,
a message to cancel requesting a query transferred to server is sent. The return
value can depend on the disconnect_on_query_timeout configuration; even though the
message to cancel a request is sent to server, that request may succeed.
-
disconnect_on_query_timeout : Configures a value whether to immediately return
an error of function being executed upon timeout. The default value is false.
Note:
? and : that are used as identifiers
in PHP connection URL can't be included in the password. The following is
an example of a password that is invalid to use as connection URL because it contains
"?:".
$url = "CUBRID:localhost:33000:tdb:dba:12?:?login_timeout=100";
Passwords that contain ? or :
may be passed as a separate parameter.
$url = "CUBRID:localhost:33000:tbd:::?login_timeout=100";
$conn = cubrid_connect_with_url($url, "dba", "12?");
If user or password is empty,you can't delete ":",the following is
an example.
$url = "CUBRID:localhost:33000:demodb:::";
인수
-
conn_url
-
A character string that contains server connection information.
-
userid
-
User name for the database.
-
passwd
-
User password.
-
new_link
-
If a second call is made to
cubrid_connect_with_url() with the same arguments,
no new connection will be established, but instead, the connection
identifier of the already opened connection will be returned. The
new_link parameter modifies this behavior and
makes cubrid_connect_with_url() always open a new
connection, even if cubrid_connect_with_url() was
called before with the same parameters.
반환값
Connection identifier, when process is successful.
FALSE, when process is unsuccessful.
