Export Data to CSV and Download Using PHP and MySQL

Here, we have a sample result set from MySQL and want to export it in a CSV file.

Step 1: Create sample MySQL data in key-value pair.

$data = array(
 '0' => array('Name'=> 'Parvez', 'Status' =>'complete', 'Priority'=>'Low', 'Salary'=>'001'),
 '1' => array('Name'=> 'Alam', 'Status' =>'inprogress', 'Priority'=>'Low', 'Salary'=>'111'),
 '2' => array('Name'=> 'Sunnay', 'Status' =>'hold', 'Priority'=>'Low', 'Salary'=>'333'),
 '3' => array('Name'=> 'Amir', 'Status' =>'pending', 'Priority'=>'Low', 'Salary'=>'444'),
 '4' => array('Name'=> 'Amir1', 'Status' =>'pending', 'Priority'=>'Low', 'Salary'=>'777'),
 '5' => array('Name'=> 'Amir2', 'Status' =>'pending', 'Priority'=>'Low', 'Salary'=>'777')
);

Step 2: PHP code to get options type and force to browser download file instead of display.

if(isset($_POST["ExportType"]))
{
  
    switch($_POST["ExportType"])
    {
  case "export-to-csv" :
            // Submission from
   $filename = $_POST["ExportType"] . ".csv";   
   header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
   header("Content-type: text/csv");
   header("Content-Disposition: attachment; filename=\"$filename\"");
   ExportCSVFile($data);
   //$_POST["ExportType"] = '';
            exit();
        default :
            die("Unknown action : ".$_POST["action"]);
            break;
    }
}
function ExportCSVFile($records) {
 // create a file pointer connected to the output stream
 $fh = fopen( 'php://output', 'w' );
 $heading = false;
 if(!empty($records))
   foreach($records as $row) {
  if(!$heading) {
    // output the column headings
    fputcsv($fh, array_keys($row));
    $heading = true;
  }
  // loop over the rows, outputting them
   fputcsv($fh, array_values($row));
   
   }
   fclose($fh);
}

Here we are setting header information to tell the browser that we are producing a CSV file and that the file should be offered for download.

Step 3: Define HTML layout for displaying data in table and button to fire export-to-csv action.

<div><a  (0)" id="export-to-csv">Export to csv</a></div>
 <form action="<?php echo $_SERVER["PHP_SELF"]; ?>" method="post" id="export-form">
            <input type="hidden" value='' id='hidden-type' name='ExportType'/>
            </form>
                  <table id="" class="table table-striped table-bordered">
                    <tr>
                        <th>Name</th>
                        <th>Status</th>
                        <th>Priority</th>
                        <th>Salary</th>
                  </tr>
                <tbody>
                  <?php foreach($data as $row):?>
          <tr>
          <td><?php echo $row ['Name']?></td>
          <td><?php echo $row ['Status']?></td>
          <td><?php echo $row ['Priority']?></td>
          <td><?php echo $row ['Salary']?></td>
          </tr>
          <?php endforeach; ?>
                </tbody>
              </table>

Step 4: Now we will use jQuery code to get the click event.

<script type="text/javascript">
$(document).ready(function() {
jQuery('#export-to-csv').bind("click", function() {
var target = $(this).attr('id');
switch(target) {
 case 'export-to-csv' :
 $('#hidden-type').val(target);
 //alert($('#hidden-type').val());
 $('#export-form').submit();
 $('#hidden-type').val('');
 break
}
});
    });
</script>

Result:

I hope this helps you!.
