cubrid_pconnect_with_url — Open a persistent connection to CUBRID server
$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
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";
$conn = cubrid_pconnect_with_url ($url, "dba", "12?");
If user or password is empty,you can't delete ":",the following is an example.
$url = "CUBRID:localhost:33000:demodb:::";
conn_url
A character string that contains server connection information.
userid
User name for the database.
passwd
User password.
Connection identifier, when process is successful.
FALSE
, when process is unsuccessful.
Example #1 cubrid_pconnect_with_url() url without properties example
<?php
$conn_url = "CUBRID:127.0.0.1:33000:demodb:dba::"
$con = cubrid_pconnect_with_url ( $conn_url );
if ( $con ) {
echo "connected successfully" ;
cubrid_execute ( $con , "create table person(id int,name char(16))" );
$req = cubrid_execute ( $con , "insert into person values(1,'James')" );
if ( $req ) {
cubrid_close_request ( $req );
cubrid_commit ( $con );
} else {
cubrid_rollback ( $con );
}
cubrid_disconnect ( $con );
}
?>
Example #2 cubrid_pconnect_with_url() url with properties example
<?php
$conn_url = "CUBRID:127.0.0.1:33000:demodb:dba::?althost=10.34.63.132:33088&rctime=100"
$con = cubrid_pconnect_with_url ( $conn_url );
if ( $con ) {
echo "connected successfully" ;
$req = cubrid_execute ( $con , "insert into person values(1,'James')" );
if ( $req ) {
cubrid_close_request ( $req );
cubrid_commit ( $con );
} else {
cubrid_rollback ( $con );
}
cubrid_disconnect ( $con );
}
?>
