PHP How to convert array into csv using fputcsv function

Question

please I have the following array :

array(3) {
  [0]=>
  array(2) {
    [0]=>
    string(6) "lkjhgj"
    [1]=>
    string(16) "jhgjhg@jhgjj.com"
  }
  [1]=>
  array(2) {
    [0]=>
    string(5) "hgjk,"
    [1]=>
    string(18) "kjhgfghj@dgdfg.com"
  }
  [2]=>
  array(2) {
    [0]=>
    string(9) "dddd ffff"
    [1]=>
    string(13) "dddd@gmail.fr"
  }
}

I want to put it into a csv file, so I've tried :

$fichier = 'file.csv';
$fp = fopen($fichier, 'w');

foreach ($list as $fields) 
{
   fputcsv($fp, $fields);
}

fclose($fp);

header( 'Content-Type: text/csv' );
header( 'Content-Disposition: attachment;filename='.$fichier);

But when I download the file I found it empty !

Please masters any idea ? Thanks in advance

Where does `$list` come from in your code example? What's in there? — Pekka, Feb 11 '13 at 09:25
I don't see any code that actually returns the file as part of the response! After you've closed the file it's got to be reopened before you can send it. Also I don't see any error checking in your code, fopen, fputcsv and other file operations can fail. You need to check that they've not returned FALSE — GordonM, Feb 11 '13 at 09:25
use `$fp= fopen('php://output', 'w');` instead of `$fp = fopen($fichier, 'w');`.. see my answer below — Suhel Meman, Feb 11 '13 at 09:28

 $fichier = 'file.csv';
 header( "Content-Type: text/csv;charset=utf-8" );
 header( "Content-Disposition: attachment;filename=\"$fichier\"" );
 header("Pragma: no-cache");
 header("Expires: 0");

 $fp= fopen('php://output', 'w');

 foreach ($list as $fields) 
 {
    fputcsv($fp, $fields);
 }
 fclose($fp);
 exit();

If you are saving array in session and issues of encoded characters.

session_start();
$fp = fopen($_SESSION['CSV']['type'].'.csv', 'w');
foreach ($_SESSION['CSV'] as $fields) {
    $val1 = htmlspecialchars_decode(utf8_decode(html_entity_decode($fields[0], ENT_QUOTES | ENT_XML1, 'UTF-8')));
    $val2 = htmlspecialchars_decode(utf8_decode(html_entity_decode($fields[1], ENT_QUOTES | ENT_XML1, 'UTF-8')));
    $val3 = htmlspecialchars_decode(utf8_decode(html_entity_decode($fields[2], ENT_QUOTES | ENT_XML1, 'UTF-8')));
    fputcsv($fp, array($val1,$val2,$val3,$val4,$val5));
}
fclose($fp);

if somebody is looking for exporting the results from a query with dynamic headers to an array then to csv file you could use the following function :

function exportCSVFile($fieldsNames, $result)
{

$fileName = "result.csv";
header("Content-type: text/csv");
header("Content-Disposition: attachment; filename=$fileName");
header("Pragma: no-cache");
header("Expires: 0");
$stdout = fopen('php://output', 'w');

fputcsv($stdout, $fieldsNames, ',', '"'); // put the headers or fields Names

$resultArray = array();

$tempRowHolder = array();

/* 
    build the finalized array which will be used to export the result as csv 
*/

for ($i = 0; $i < count($result); $i++) {
    for ($j = 0; $j < count($fieldsNames); $j++) {
        $tempRowHolder[$j] = $result[$i][$fieldsNames[$j]]; // fetch a row by the different fields names
    }

    /* push the row from the tempRowHolder array to the main array($resultArray) */
    array_push($resultArray, $tempRowHolder);

    /* clear the temporary array (the holder of the row) to use it fresh in the next iteration */
    $tempRowHolder = [];
}

$i = 0;

/* put the finalized array into the csv file  */
while ($i < count($resultArray)) {
    fputcsv($stdout, $resultArray[$i++]);
}

fclose($stdout);
}
