How to retrieve a table output parameter from sql server stored procedure to php variable? I've the following code that returns a table from the query. The table needs to be retrieved in PHP and formatted before being printed onto a file. ## Stored Procedure: @query1 has a table from select statement that is pivoted. EXEC SP_EXECUTESQL @query= @query1, @params= N'@queryO NVARCHAR(MAX) OUTPUT', @queryO= @queryO OUTPUT; declare @getProducts NVARCHAR(MAX) select @getProducts= @queryO; ## The PHP code follows: $stmt2 = sqlsrv_query($conn, $tsql_createSP); if( $stmt2 === false ) { echo "Error in executing statement 2.\n"; die( print_r( sqlsrv_errors(), true)); } $getProducts="ABCD"; $params = array( array($chrom_set,SQLSRV_PARAM_IN), array($getProducts,SQLSRV_PARAM_OUT) ); $tsql_callSP = "{call spGetPivot( ?,? OUTPUT)}"; $stmt3 = sqlsrv_query($conn,$tsql_callSP,$params); if ( $stmt3 === false) { echo "Error in executing statement 3.\n"; die( FormatErrors( sqlsrv_errors() ) );} $productCount = 0; function cleanData($str) { $str = preg_replace("/\t/", "\\t", $str); $str = preg_replace("/\r?\n/", "\\n", $str); $str=str_replace("\\n","",$str); if(strstr($str, '"')) $str = '"' . str_replace('"', '""', $str) . '"'; } // file name for download $filename = "NAM_data_" . date('YmdHis') ."_pg".".txt"; header("Content-Disposition: attachment; filename=\"$filename\""); header("Content-Type: text/plain"); $flag = false; while( $row = sqlsrv_fetch_array( $getProducts, SQLSRV_FETCH_ASSOC)){ if(!$flag){ // display field/column names as first row array_walk($row, 'cleanData'); echo implode("\t", array_keys($row)) . "\r\n"; $flag = true; } array_walk($row, 'cleanData'); echo implode("\t", array_values($row)). "\r\n"; } sqlsrv_free_stmt( $stmt1); sqlsrv_free_stmt( $stmt2); sqlsrv_free_stmt( $stmt3); sqlsrv_close( $conn); I'm not able to retrieve the output with this code. The query works well in this format in SSMS.
