interpréter entier en tant que chaîne csv

Question

J'ai trouvé ce code à la sortie d'une table SQL dans CSV, qui fonctionne très bien, mais dans le tableau je tire de nous utilisons des entiers pour représenter deux valeurs différentes dans deux colonnes différentes, par exemple, devrait '0' lu comme 'All' dans column A, et '0' devrait se lire comme 'New' dans Column B. J'ai du mal à comprendre comment interpréter 0 comme deux choses différentes, car je ne peux pas simplement dire '0 = X' pour toutes les valeurs. Toute idée serait appréciée:

<?php 
    session_start(); 
    if (isset($_POST['export']) && !empty($_POST['export'])){ 
    if($_POST['export'] == 'safefilter') { 

      $colnames = [ 
      'team' => "Team", 
      'name' => "INI", 
      'inidesc' => "INI Description", 
      'item' => "Item", 
      'itemdesc' => "Item Description", 
      'newonly' => "New Only?", 
      ]; 

      $filter = $_POST['filter']; 
      $name = $filter . 'StandardFiles'; 

      if (in_array($filter, $_SESSION['teamarray'], true)) { 

      $sql = "SELECT DISTINCT teams.team, safecheck.name, safecheck.inidesc, safecheck.item, safecheck.itemdesc, safecheck.newonly FROM safecheck INNER JOIN teams ON safecheck.teamid=teams.id WHERE team = '$filter' ORDER BY name ASC, team ASC, item ASC;"; 

      } elseif (in_array(strtoupper($filter), $_SESSION['iniarray'], true)) { 

      $sql = "SELECT DISTINCT teams.team, safecheck.name, safecheck.inidesc, safecheck.item, safecheck.itemdesc, safecheck.newonly FROM safecheck INNER JOIN teams ON safecheck.teamid=teams.id WHERE name = '$filter' ORDER BY name ASC, team ASC, item ASC;";

dans vos instructions SQL procédez comme suit pour les colonnes:

SELECT IF(column_name_A = 0, 'All', column_name_A) FROM your_table 

SELECT IF(column_name_B = 0, 'New', column_name_B) FROM your_table
