displaying the mismatch into the excel using php - excel

Question

I am importing the the csv data into the database, records which are not matching with the dtdc are the mismatch are mismatched records . I am exporting those records into excel.Below is the else condition which we are taking the mismatch records
else{
$mismarchrows_dtdc[] = $row['Postcode'];
$mismatchcount_dtdc = $mismatchcount_dtdc+1;
}
Here i am writing the mismatched records into excel
$fileName_dtdc = 'uploads/csv/already_exist_customer_dtdc-'.time().'.xls';
$fp = fopen($fileName_dtdc, 'w');
$newLineSeparator = "\r\n";
$line1_dtdc = 'postcode'.$newLineSeparator;
fwrite($fp,$line1_dtdc);
foreach($mismarchrows_dtdc as $mrow){
$line2_dtdc = $mrow;
fwrite($fp,$line2_dtdc);
}
now only one column called postcode is only exported into excel, but i 5 more columns like firstname,lastname,middlename in to the excel with data
I tried by keeping like this, But coming in only one column
else{
$mismarchrows_dtdc[] = $row['Postcode'];
$mismarchrows_dtdc1[] .= $row['State'];
$mismatchcount_dtdc = $mismatchcount_dtdc + 1;
}
can anyone help with this !!!!!!!!!!!!!!!!!

I don't know your exact needs, but maybe this will help?
$csv_lines = array();
foreach($mismarchrows_dtdc as $mrow) {
$keys = array_keys($mrow);
$data = array();
foreach ($keys as $key) {
$data[] = $mrow[$key];
}
$csv_lines[] = implode(',',$data);
}
$fileName_dtdc = 'uploads/csv/already_exist_customer_dtdc-'.time().'.xls';
file_put_contents($fileName_dtdc,implode("\r\n",$csv_lines));
