将SQL查询导出到CSV文件

Question

我需要将SQL查询导出到.csv文件。我在导出查询时使用的代码，但.csv文件在信息开头之上有2行空格。它也是（TABS）带头的第一行。有没有阻止这个？

这是我的代码：

   $comments = array(",", "\r\n", "\r", "\n");

// EXPORT STREAMLINE.CSV

    header('Content-type: text/csv');

    header('Content-Disposition: attachment; filename="streamline.csv"');  

    readfile('streamline.csv');

    $vaStreamline = $dataConnection->SelectAllWhere( "applicants", "loan_purpose='VA Streamline' AND statusdate >= '3/1/2011'", "ORDER BY statusdate DESC" );   


    echo "applicantid,active,fromsite,siteref,category,staus,statusdate,preapproved_email1,preapproved_email2,preapproved_email3,finalstatus,datefinalstatus,loan_purpose,current_rate,loan_balance,estimated_value,b_firstname,b_middlename,b_lastname,b_ssno,b_dob,b_marital,b_creditreport,b_disability,prop_address,prop_city,prop_state,prop_zip,prop_type,b_workphone,b_extension,b_homephone,b_email,b_emp_lastyeargross,coborrower,cb_firstname,cb_middlename,cb_lastname,cb_ssno,liab_latepayments,mortgage_latepayments_monthly,datecompleted,comments,mortgage_type,current_add_diff,cur_address,cur_city,cur_state,cur_zip,liab_credit_score,c_name \r\n";

     for( $i = 0 ; $i < count( $vaStreamline ) ; $i++ ) 

     echo $vaStreamline[$i][ 'applicantid' ] . ',' . $vaStreamline[$i][ 'active' ] . ',' . $vaStreamline[$i][ 'fromsite' ] . ',' . $vaStreamline[$i][ 'siteref' ] .
