# cubrid_pconnect_with_url

(PECL CUBRID >= 8.3.1)

cubrid_pconnect_with_url — Open a persistent connection to CUBRID server

### Beschreibung

resource cubrid_pconnect_with_url ( string `$conn_url` [, string `$userid` [, string `$passwd` ]] )

Establishes a persistent connection to a CUBRID server.

cubrid_pconnect_with_url() acts very much like cubrid_connect_with_url() with two major differences.

First, when connecting, the function would first try to find a (persistent) link that's already open with the same host, port, dbname and userid. If one is found, an identifier for it will be returned instead of opening a new connection.

Second, the connection to the SQL server will not be closed when the execution of the script ends. Instead, the link will remain open for future use ( cubrid_close() or cubrid_disconnect() will not close links established by cubrid_pconnect_with_url()).

This type of link is therefore called 'persistent'.

<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

<alternative_hosts> ::= <standby_broker1_host>:<port> [,<standby_broker2_host>:<port>]

<host> := HOSTNAME | IP_ADDR

<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.

> Hinweis:

> ? 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:::";
