与ORACLE连接

Question

What are the most important conditions for a PHP connection with ORACLE?

I already wrote these extensions in PHP.ini and it did not work

extension=oci8_12c  ; Use with Oracle Database 12c Instant Client
extension=php_oci8.dll
extension=php_oci8_12c.dll
extension=php_oracle.dll
extension=pdo_odbc
extension=pdo_pgsql

Code Used

    <?php

    $conn="(DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.9)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = PRD)
      (SERVER = DEDICATED)
    )
    )";
    $conexao = oci_connect('DBA', '123', $conn);

    if (isset ($conexao) || empty($conexao)){
        $erro = oci_error();
        trigger_error(htmlentities($erro['erro'], ENT_QUOTES), E_USER_ERROR);
    exit;
    }

    echo"Hello";

?>

Errors

Fatal error: Uncaught Error: Call to undefined function oci_connect() in C:\wamp64\www\Teste\testes\conexaooracle.php on line 12 

Error: Call to undefined function oci_connect() in C:\wamp64\www\Teste\testes\conexaooracle.php on line 12

The most important thing is to install the Oracle client libraries. If you don't have them on your machine, you can get these from Oracle Instant Client

Once unzipped, set PATH environment variable to find them.

Only uncomment one of the extension lines to include OCI8. You probably just need

extension=oci8_12c  ; Use with Oracle Database 12c Instant Client

This will actually work with 12c or later versions of Oracle Client libraries.

A useful PHP Oracle resource is the back half of http://www.oracle.com/technetwork/topics/php/underground-php-oracle-manual-098250.html

PS you can simplify your connection to:

$conexao = oci_connect('DBA', '123', '192.168.0.9/PRD');
