PHP删除二维数组中相同元素及数组重复值的方法示例

本文实例讲述了PHP删除二维数组中相同元素及数组重复值的方法。分享给大家供大家参考，具体如下：

function assoc_title($arr, $key)
{
  $tmp_arr = array();
  foreach ($arr as $k => $v) {
    if (in_array($v[$key], $tmp_arr)) {
      unset($arr[$k]);
    } else {
      $tmp_arr[] = $v[$key];
    }
  }
  return $arr;
}//assoc_title end
$key_title = 'stu_name';
$quchong = assoc_title($teachers, $key_title);
echo "<table border=\"1\" bordercolor=\"#CCCCCC\" cellpadding=\"0\" cellspacing=\"0\" style=\"border-collapse:collapse\" width=\"20%\">";
echo "<tr><td>id</td><td>学生名</td><td>电话</td></tr>";
$i = 1;
foreach ($quchong as $key => $vale) {
  if ($vale['stu_name'] == "游开琳" or $vale['stu_name'] == "韩建通") {
    continue;
  }
  echo "<tr><td>{$i}</td><td>{$vale['stu_name']}</td><td>{$vale['tel']}</td></tr>";
  $i++;
}
echo "</table>";
