Hello community,
PHP is a server side scripting language, you can find more information here. PHP offers access to COM objects on Win32 platforms, all you have to do is to add the line extension=php_com_dotnet.dll in the php.ini file. In this case you have the possibility to use COM Connector (CCo), which I presented here. So you can use NetWeaver RFC Library inside PHP. Here a small example, to ping an SAP system.
At first the HTML file:
<!doctype html><html> <head> <title> Ping to an SAP system </title> </head> <body> <h1> Ping to an SAP system </h1> <form method="POST" action="0103_Ping.php"> <table border="0"> <tr> <td>Host:</td> <td><input type="text" name="ashost" size="20" value="ABAP"></td> </tr> <tr> <td>Systemnumber:</td> <td><input type="text" name="sysnr" size="20" value="00"></td> </tr> <tr> <td>Client:</td> <td><input type="text" name="client" size="20" value="001"></td> </tr> <tr> <td>Username:</td> <td><input type="text" name="user" size="20" value="bcuser"></td> </tr> <tr> <td>Password:</td> <td><input type="password" name="password" size="20" value="minisap"></td> </tr> </table> <input type="submit" name="submit" value="Submit"> </form> </body> </html>
And now the PHP file:
<!doctype html><html> <head> <title> Ping to an SAP system </title> </head> <body> <h1> Ping to an SAP system </h1><?php const RFC_OK = 0; $conn = "ASHOST=" . $_POST["ashost"] . ", "; $conn = $conn . "SYSNR=" . $_POST["sysnr"] . ", "; $conn = $conn . "CLIENT=". $_POST["client"] . ", "; $conn = $conn . "USER=" . $_POST["user"] . ", "; $conn = $conn . "PASSWD=" . $_POST["password"]; $SAP = new COM("COMNWRFC") or die ("Can't create object"); $SAP->ErrorMsgTarget = 1; //Necessary, in a normal case 2 $SAP->DebugOutput = 1; $hRFC = $SAP->RfcOpenConnection($conn); if ($hRFC <> 0) { $hFuncDesc = $SAP->RfcGetFunctionDesc($hRFC, "RFC_PING"); if ($hFuncDesc <> 0) { $hFunc = $SAP->RfcCreateFunction($hFuncDesc); if ($hFunc <> 0) { $rc = $SAP->RfcInvoke($hRFC, $hFunc); if ($rc == RFC_OK) { echo "Ping successful"; } else { echo "Ping not successful"; } } } $rc = $SAP->RfcCloseConnection($hRFC); } $SAP = null;
?> </body></html>
Here now another example to get system information via RFC-enabled function module RFC_SYSTEM_INFO. Here only the PHP file, because the HTML file is nearly the same as in the example above.
<!doctype html><html> <head> <title> System Information </title> </head> <body> <h1> System Information </h1><?php const RFC_OK = 0; $NumByRef = 0; $StrByRef = ""; $conn = "ASHOST=" . $_POST["ashost"] . ", "; $conn = $conn . "SYSNR=" . $_POST["sysnr"] . ", "; $conn = $conn . "CLIENT=". $_POST["client"] . ", "; $conn = $conn . "USER=" . $_POST["user"] . ", "; $conn = $conn . "PASSWD=" . $_POST["password"]; $SAP = new COM("COMNWRFC") or die ("Can't create object"); $SAP->ErrorMsgTarget = 1; //Necessary, in a normal case 2 $hRFC = $SAP->RfcOpenConnection($conn); if ($hRFC == 0) { echo "RfcOpenConnection not successful"; $SAP = null; exit(1); } $hFuncDesc = $SAP->RfcGetFunctionDesc($hRFC, "RFC_SYSTEM_INFO"); if ($hFuncDesc == 0) { echo "RfcGetFunctionDesc not successful"; $rc = $SAP->RfcCloseConnection($hRFC); $SAP = null; exit(1); } $hFunc = $SAP->RfcCreateFunction($hFuncDesc); if ($hFunc == 0) { echo "RfcCreateFunction not successful"; $rc = $SAP->RfcCloseConnection($hRFC); $SAP = null; exit(1); } $rc = $SAP->RfcInvoke($hRFC, $hFunc); if ($rc == RFC_OK) { $rc = $SAP->RfcGetStructure($hFunc, "RFCSI_EXPORT", $NumByRef); if ($rc == RFC_OK) { $hStruct = $SAP->lngByRef(); $rc = $SAP->RfcGetChars($hStruct, "RFCHOST", $StrByRef, 8); $charBuffer = $SAP->strByRef(); echo "Host: " . $charBuffer . "<br />"; $rc = $SAP->RfcGetChars($hStruct, "RFCSYSID", $StrByRef, 8); $charBuffer = $SAP->strByRef(); echo "SysID: " . $charBuffer . "<br />"; $rc = $SAP->RfcGetChars($hStruct, "RFCDBHOST", $StrByRef, 32); $charBuffer = $SAP->strByRef(); echo "DBHost: " . $charBuffer . "<br />"; $rc = $SAP->RfcGetChars($hStruct, "RFCDBSYS", $StrByRef, 10); $charBuffer = $SAP->strByRef(); echo "DBSys: " . $charBuffer . "<br />"; } } $rc = $SAP->RfcCloseConnection($hRFC); $SAP = null;
?> </body></html>
As you can see it is very easy to connect an SAP system from PHP via CCo.
I check it successfully with PHP version 5.5.31, 5.6.17 and 7.0.2.
Enjoy it.
Cheers
