Php 如何将pdo返回的关联数组的内容获取到数组中

我正在使用PHO-PDO并让它返回一个关联数组

我可以循环使用PDO创建的关联数组，但我无法确定如何从函数返回数组

function wantedrentals($provence, $country, $dbh)
   {
      echo "Now in wanted wanted rentals function<br><br>"; 

      $journeyrentalssarray = array();

      $sth = $dbh->query("SELECT summary, url, provence, country from tblAccomadation WHERE country = $country ");

    # setting the fetch mode
    $sth->setFetchMode(PDO::FETCH_ASSOC);

    while($row = $sth->fetch()) 
        {
            echo $row['summary'] . "\n";
            echo $row['url'] . "\n";
            echo $row['provence'] . "\n";
            echo $row['country'] . "\n";
        }

  return $journeyrentalssarray;
  }

我对PHP和PDO非常陌生，非常感谢您的帮助。

您可能希望这样做

function wantedrentals($provence, $country, $dbh)
   {
      echo "Now in wanted wanted rentals function<br><br>"; 

      $journeyrentalssarray = array();

      $sth = $dbh->query("SELECT summary, url, provence, country from     tblAccomadation WHERE country = '$country' ");

    # setting the fetch mode
    $sth->setFetchMode(PDO::FETCH_ASSOC);

    while($row = $sth->fetch()) 
        {
            $journeyrentalssarray[] = $row; // add $row to $journeyrentalssarray array
            echo $row['summary'] . "\n";
            echo $row['url'] . "\n";
            echo $row['provence'] . "\n";
            echo $row['country'] . "\n";
        }

  return $journeyrentalssarray;
  }

function wantedrentals($provence, $country, $dbh)
   {
      echo "Now in wanted wanted rentals function<br><br>"; 

      $journeyrentalssarray = array();

      $sth = $dbh->query("SELECT summary, url, provence, country from tblAccomadation WHERE country = $country ");

    # setting the fetch mode
    //$sth->setFetchMode(PDO::FETCH_ASSOC);

    return $sth->fetch(PDO::FETCH_ASSOC);
  }

FETCH_ASSOC将返回结果集中返回的按列名索引的数组

fetch函数在成功时的返回值取决于您案例中的fetch类型，失败时返回fetch_ASSOC和FALSE

我们还可以使用fetchAll获取所有结果集行的数组。 所以函数可能是这样的

function wantedrentals($provence, $country, $dbh)
       {
          echo "Now in wanted wanted rentals function<br><br>"; 

          $journeyrentalssarray = array();

          $sth = $dbh->query("SELECT summary, url, provence, country from tblAccomadation WHERE country = $country ");


        return $sth-> fetchAll(PDO::FETCH_ASSOC);
      }
