导出到CSV与表PHP不同

Question

I am trying to download table data into a CSV format. The data in one of the fields contains ",". Eg: Doe, John

When I download the csv file, the data after comma is shifted to next column. But I want the entire data ie including comma in same column.

The Code I used as follows:

<?php
include('dbconfig.php');
//header to give the order to the browser
header('Content-Type: text/csv');
header('Content-Disposition: attachment;filename=download.csv');
//select table to export the data
$sql ="SELECT * FROM tablename";
$select_table=mysqli_query($db, $sql);
$rows = mysqli_fetch_assoc($select_table);

if ($rows)
{
getcsv(array_keys($rows));
}
while($rows)
{
 getcsv($rows);
 $rows = mysqli_fetch_assoc($select_table);
 }

  // get total number of fields present in the database
 function getcsv($no_of_field_names)
 {
   $separate = '';


  // do the action for all field names as field name
  foreach ($no_of_field_names as $field_name)
 {
 if (preg_match('/\\r|\\n|,|"/', $field_name))
 {
  $field_name = '' . str_replace('<em>', '', $field_name) . '';
  }
  echo $separate . $field_name;

 //sepearte with the comma
 $separate = ',';
  }

//make new row and line
echo "\r\n";
}
?>

Can someone help me get through this issue. Thanks

Answer 1

Make sure you escape the , . Typically values that contain sensitive characters (such as , and \\n ) are surrounded in " .

So your output can be:

 "Doe, John",52,New York

You can either write your own escape function or use PHPs fputcsv . It writes to a file handler that's a bit inconvenient but you can make it stdout .

$handle = fopen("php://stdout");
fputcsv($handle, array("Doe, John", 52, "New York"));
