<?php

$con = mysqli_connect( "localhost","root","","teste" ); // ◄■ CONNECT TO DATABASE.


        //$id_resp = (isset($_POST['id_resp']) ? $_POST['id_resp'] : '');
        //$id = $_SESSION['UtilizadorID'];

        //$data = (isset($_POST['data']) ? $_POST['data'] : '');

    $file = fopen("teste.csv","a"); //filename

I change the POST variable to array variable with following output:

array(8) { ["corp_resp&77&2&2017-09-07&80&76"]=> string(4) "0.00" ["corp_resp&78&2&2017-09-07&80&76"]=> string(4) "0.00" ["corp_resp&79&2&2017-09-07&80&76"]=> string(4) "0.00" ["corp_resp&80&2&2017-09-07&80&76"]=> string(4) "0.00" ["corp_resp&81&2&2017-09-07&80&76"]=> string(4) "0.30" ["corp_resp&82&2&2017-09-07&80&76"]=> string(4) "0.00" ["corp_resp&83&2&2017-09-07&80&76"]=> string(4) "0.00" ["corp_resp&84&2&2017-09-07&80&76"]=> string(4) "0.70" } array(1) { [0]=> string(4) "0.70" }


 if ( isset($_POST) ) {

   foreach ( $_POST as $key  )
      $cr = explode( "&",$key );
        //mysqli_query( $con,"insert into tem (menuid,corp_resp_template,id,data,id_tem,menuIdPai) " .
          //                              "values ('{$cr[1]}','$value', '{$cr[2]}', '{$cr[3]}', '{$cr[4]}', '{$cr[5]}')" );

I am introducing for database but i want to introduce to csv.

I try in that way to csv file. But is empty $csv only with ;

    var_dump($cr);
         $csv = $cr[1].";".$value.";".$cr[3].";".$cr[4].";".$cr[5];

             var_dump($csv);

                   //fputcsv($file,explode(';',$csv), ";");


fclose($file);
 }
  else {

     echo "task option is required";
     exit;
   }




        echo "<center>AdicIonada com sucesso.</center>";
        echo '<br>';
        echo '<br>';
