php - Issue with EXPORT to CSV FILE -


i want export write in input text :

-i have created class called "excelfile", contain methods exporting data csv file.

-i have issue, when try export file data, colone added automatically in csv file, colone contain code html of table

-this code :

excelfile.php

<?php class excelfile {      private     $csv = null;      function colonne($file) {          $this->csv.=$file."\n";         return $this->csv;      }       function insertion($file){          $this->csv.=$file."\n";         return $this->csv;     }       function output($nomfichier){          header("content-type: application/vnd.ms-excel");         header("content-disposition: attachment; filename=$nomfichier.csv");         print $this->csv;         exit;      } }  ?>

index.php

<?php include_once 'excelfile.php'; ?> <html>  <form method='post' action="index.php">     <table>         <tr>             <td><label>first name</label></td>             <td><input type='text' name='tfirst' /></td>         </tr>          <tr>             <td><label>last name</label></td>             <td><input type='text' name='tlast' /></td>         </tr>          <tr>             <td><input type='submit' name='btnsave' value='export csv file' /></td>         </tr>      </table> </form> </html> <?php if (isset ( $_post ["btnsave"] )) {      test (); } function test() {     $excelfile = new excelfile ();     $excelfile->colonne ( "first name;last name" );     $excelfile->insertion ( $_post ['tfirst'] . ';' . $_post ['tlast'] );     $excelfile->output ( 'export result' );  } ?>

your output() function called after have sent whole html document, why included in file.

you need move code around bit index.php file looks more this:

<?php include_once 'excelfile.php';  if (isset ( $_post ["btnsave"] )) {      test ();     exit; //you want end here, html below not in csv }  function test() {     $excelfile = new excelfile ();     $excelfile->colonne ( "first name;last name" );     $excelfile->insertion ( $_post ['tfirst'] . ';' . $_post ['tlast'] );     $excelfile->output ( 'export result' );  } ?> <html>  <form method='post' action="index.php">     <table>         <tr>             <td><label>first name</label></td>             <td><input type='text' name='tfirst' /></td>         </tr>          <tr>             <td><label>last name</label></td>             <td><input type='text' name='tlast' /></td>         </tr>          <tr>             <td><input type='submit' name='btnsave' value='export csv file' /></td>         </tr>      </table> </form> </html>

(side note: please consider using php framework)

(side note: please consider using commas separate values instead of semi-colons)
