在变量php中有两个数组

Question

我有这段代码，我正试图分解我的日期例如"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所有的，有一个数组，这可能吗，我的代码不起作用，它写"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，因为它对循环的每个结果都重复04。

Answer 1

爆炸函数使用正确，因此您的问题更严重。

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

或

您的函数$data[$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进行进一步测试，一次一行，以确保您得到了所需的字符串。在data_eng_to_it_功能中，您是否记得return $data？

编辑：

您正在回显$data_exploded[0]，它将输出"Array"。相反，输出2D数组，因此$data_exploded[0]将输出"04"。或者要查看$data_exploded[0]的完整输出，请使用：var_dump($data_exploded[0]);

要使其在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.将其连接起来，或者将其分配给一个更简单的变量。

1. 更简单的变量：$day=$data_exploded[$i][0]，并使用与
2. 连接：echo "<h1>".$data_exploded[$i][0]."</h1>";
3. 拆分HTML和PHP：我个人会这么做：?> <h1><?php echo $data_exploded[$i][0];?></h1>
