This extension is intended to provide a means for PHP 7 developers to interface with the SAP NetWeaver SDK.

To build or install this extension you need to obtain a copy of the SAP NetWeaver RFC SDK from the SAP Service Marketplace. You can follow the instructions here.

Follow the build instructions.

Enable the extension in your php.ini:

# for Linux/Unix
extension=sapnwrfc.so

# for Windows
extension=php_sapnwrfc.dll

You can verify that the extension is loaded by running php -m | grep sapnwrfc.

This simple example shows how to call a (fictional) RFC function and get its return value:

use SAPNWRFC\Connection as SapConnection;
use SAPNWRFC\Exception as SapException;

$config = [
    'ashost' => 'my.sap.system.local',
    'sysnr'  => '00',
    'client' => '123',
    'user' => 'DEMO',
    'passwd' => 'XXXX',
    'trace'  => SapConnection::TRACE_LEVEL_OFF,
];

try {
    $c = new SapConnection($config);

    $f = $c->getFunction('Z_TEST_FUNCTION');
    $result = $f->invoke([
        'CHAR1' => 'A',
        'TABL' => [
            ['INT4' => 1, 'CHAR4' => 'NOPE'],
        ]
    ]);

    var_dump($result);
} catch(SapException $ex) {
    echo 'Exception: ' . $ex->getMessage() . PHP_EOL;

    /*
     * You could also catch \SAPNWRFC\ConnectionException and \SAPNWRFC\FunctionCallException
     * separately if you want to.
     */
}
