Question

我有这样的foreach循环。

if ( is_object($res_two)) {
  if($res_two->num_rows() == 0) { 
    echo "No Records Found";}
  else if( $res_two->num_rows() > 0) {
    foreach ($res_two->result() as $row ) {
      echo $row->js_id."\t". $row->designation."\t".$row->full_name."\t".$row->location."\t".$row->graduated_in."\t";     
      $mail2 =  $row->email;      
      echo $mail2 ;

      ?>  <a href="<?php echo base_url("uploads/".$row->resume."")?>">Download Resume</a> <br/><br/>  <?php
    }
  }
}
?>

现在我要提取$ mail2详细信息。但是，在代码中回显$ mail2只给出一个值而不是数组（如果foreach循环迭代，它应该有多个值？）。

如何在代码外获取$ mail2的多个值？

<?php
if (is_object($res_two)) {
    if ($res_two->num_rows() == 0) {
        echo "No Records Found";
    } else if ($res_two->num_rows() > 0) {
        foreach ($res_two->result() as $row) {
            echo $row->js_id . "\t" . $row->designation . "\t" . $row->full_name . "\t" . $row->location . "\t" . $row->graduated_in . "\t";
            $mail2[] = $row->email;

            ?>  <a href="<?php echo base_url("uploads/" . $row->resume . "") ?>">Download Resume</a> <br/><br/>  <?php
        }
    }
}
print_r($mail2);
?>

如何从foreach循环中获取数组值？
