我有这个代码，我正试图爆炸我的约会对象 例如“2015 年 6 月 4 日” 在其他 2 个变量中有日期和月份，但我在一个方法中有一个数组，是否可能， 我的代码不起作用，它写着“Array[0]”，为什么？

while ($i < $number) {

      $festa[$i] = mysql_result($result,$i,"festa");
      $luogo[$i] = mysql_result($result,$i,"luogo");
      $idfesta[$i] = mysql_result($result,$i,"ID");
      $data[$i] = mysql_result($result,$i,"data");  
      $nomeimg[$i] = mysql_result($result,$i,"nomeimg");

      $data[$i] = data_eng_to_it_($data[$i]);

      $data_exploded[$i] = explode(" ", $data[$i]);

      $data_exploded[$i][0] ; //day
       $data_exploded[$i][1] ; //month
        $data_exploded[$i][2] ; //year

编辑

在这种情况下:

while ($i < $number) {

      $festa[$i] = mysql_result($result,$i,"festa");
      $luogo[$i] = mysql_result($result,$i,"luogo");
      $idfesta[$i] = mysql_result($result,$i,"ID");
      $data[$i] = mysql_result($result,$i,"data");  
      $nomeimg[$i] = mysql_result($result,$i,"nomeimg");

      $data[$i] = data_eng_to_it_($data[$i]);

      $data_exploded = explode(" ", $data[$i]);

      $data_exploded[$i][0] ; //day
       $data_exploded[$i][1] ; //month
        $data_exploded[$i][2] ; //year

       echo" 
                              <div class=\"circleBase type3\"><div style=\"text-align:center;\">
                              <br>
                             <font size=\"+2\" style=\"margin-left:4px;\"> $data_exploded[0] </font>

它正确地返回“04”，但我不能使用它，因为它为我的循环的每个结果重复 04。

最佳答案

explode 函数使用正确，所以你的问题更上一层楼。

或者$data[$i] = mysql_result($result,$i,"data");没有从数据库返回预期的字符串“2015-06-04”

或

你的函数$data[$i] = data_eng_to_it_($data[$i]);没有返回预期的字符串“2015 年 6 月 4 日”

因此，在这两行之后通过 echo/var_dump 进一步测试，一次一个，以确保您获得了您期望的字符串。 在data_eng_to_it_函数你记得return $data ？

编辑:

你在回显$data_exploded[0]这将输出“数组”。而是输出二维数组，因此 $data_exploded[0][0] 将输出“04”。或者查看 $data_exploded[0] 的完整输出，使用:var_dump($data_exploded[0]);

要使其在您的 while 循环中工作，请使用 $data_exploded[$i][0]

但是您不能在回显字符串“”中执行此操作。使用 . 连接它或将其分配给更简单的变量。

1. 更简单的变量:$day = $data_exploded[$i][0] 并以与您相同的方式使用 day 变量
2. 连接:echo "<h1>".$data_exploded[$i][0]."</h1>";
3. 拆分 HTML 和 PHP:我个人会这样做:?> <h1><?php echo $data_exploded[$i][0];?></h1>
