# oci_pconnect

(PHP 5)

oci_pconnect -- Connect to an Oracle database using a persistent connection

## Description

resource oci_pconnect ( string username, string password [, string db [, string charset]] )

oci_pconnect() creates a new persistent connection to an Oracle server and logs on. The optional third parameter can either contain the name of the local Oracle instance or the name of the entry in `tnsnames.ora`. If the third parameter is not specified, PHP uses environment variables ORACLE_SID and TWO_TASK to determine the name of local Oracle instance and location of `tnsnames.ora` accordingly.

Com o Oracle server 9.2 e seguintes, você pode indicar o parâmetro charset, que será utilizado na nova conexão. Se você estiver utilizando Oracle server < 9.2, este parâmetro será ignorado e a variável de ambiente NLS_LANG deverá ser utilizada.

oci_pconnect() returns connection identifier or `FALSE` on error.

> Nota: Note, that these kind of links only work if you are using a module version of PHP. See the Persistent Database Connections section for more information.

> Nota: In PHP versions before 5.0.0 you must use ociplogon() instead. This name still can be used, it was left as alias of oci_pconnect() for downwards compatability. This, however, is deprecated and not recommended.
