我是PHP SAP RFC的新手。我使用我们的集成函数，但现在我需要从表中读取行。但是我怎么能只阅读几行，按条件过滤结果，因为这个表有数百万行。
可能吗？
这是最近使用的代码部分，在非常大的表格上也能很好地快速运行。我希望它也能帮助其他人。
//Try to connect to SAP using our Login array
$rfc = saprfc_open ($saplogin);
IF (! $rfc ) { ECHO "The RFC connection has failed with the following error:".saprfc_error();EXIT; }
//We must know if the function really exists
$fce = saprfc_function_discover($rfc, "RFC_READ_TABLE");
IF (! $fce ) { ECHO "The function module has failed.";ECHO $rfc;EXIT; }
//Convert to uppercase the name of the table to show
$Table = "HERE_THE_TABLE_NAME";
//Pass import parameters
saprfc_import ($fce,"QUERY_TABLE",$Table);saprfc_import ($fce,"DELIMITER","/");
//Pass table parameters
saprfc_table_init ($fce,"OPTIONS");
saprfc_table_append ($fce,"OPTIONS", array ("TEXT"=>"TABLE_FIELD_NAME = '{$input}'")); //input field, filter by this variable
saprfc_table_init ($fce,"FIELDS");
saprfc_table_append ($fce,"FIELDS", array ("FIELDNAME"=>"INT_UI")); //wanted answer field
saprfc_table_init ($fce,"DATA");
//Call and execute the function
$rc = saprfc_call_and_receive ($fce);
if ($rc != SAPRFC_OK)
{
if ($rfc == SAPRFC_EXCEPTION ) { echo ("Exception raised: ".saprfc_exception($fce)); }
else { echo ("Call error: ".saprfc_error($fce)); }
exit;
}
//Fetch the data from the internal tables
$data_row = saprfc_table_rows ($fce,"DATA");$field_row = saprfc_table_rows ($fce,"FIELDS");
for($i=1; $i<=$data_row ; $i++)
{ $DATA[$i] = saprfc_table_read ($fce,"DATA",$i);$TEST[] = SPLIT("/",$DATA[$i]['WA']); } // get the rows to $TEST variable
//release the function and close the connection
saprfc_function_free($fce);
