Question

我厌倦了将数据更新到table_course

<?php

// update the ite_aps data into sgc table

require_once('../../includes/common.php');

$m = array();
$result = mysql_query("SELECT * from sgc where year = '2008'") or die(mysql_error());

while($row = mysql_fetch_array($result))
  {
      //echo $row['nric'];
      $res =mysql_query("select COURSE_TITLE_LONG, CRSE_GRADE_OFF, UNT_EARNED, nric from ite where nric = '".$row['nric']."' AND STRM = '2008'")or die(mysql_error()); 
      $norows=mysql_num_rows($res);
      echo $norows."<br>";
      $update = 'UPDATE sgc SET meta_ite = ';
      while($rows = mysql_fetch_array($res))
      {
          for($i=0;$i<$norows;$i++){
          $data = array("course" => "'".$rows['COURSE_TITLE_LONG']."'" , "Grade" => "'".$rows['CRSE_GRADE_OFF']. "'" , "Unit" => "'".$rows['UNT_EARNED']."'");
          $m = serialize($data);
          }
          print $m."<br>";
          $update .= '"'.mysql_real_escape_string($m).'"'; 

      }
      $update .= 'WHERE nric = "'.$row['nric'].'" AND year = "2008"' ;
      print $update."<br>";
     // mysql_query($update);
    }

＆GT;

我得到以下输出以上编码

a:3:{s:6:"course";s:24:"'Personal Effectiveness'";s:5:"Grade";s:3:"'S'";s:4:"Unit";s:3:"'3'";}
a:3:{s:6:"course";s:16:"'Basic Numeracy'";s:5:"Grade";s:3:"'U'";s:4:"Unit";s:3:"'2'";}
a:3:{s:6:"course";s:23:"'Piping & Valve System'";s:5:"Grade";s:3:"'D'";s:4:"Unit";s:3:"'6'";}
a:3:{s:6:"course";s:24:"'Mechanical Fabrication'";s:5:"Grade";s:3:"'F'";s:4:"Unit";s:3:"'6'";}

输出格式为：array(course,grade,unit)array(course,grade,unit) - in serialize

但是，我想要这种格式的输出：array(array(course,grade,unit),array(course,grade,unit)........) -in serialize

例如：a:5:{a:3:{s:6:"course";s:24:"'Personal Effectiveness'";s:5:"Grade";s:3:"'S'";s:4:"Unit";s:3:"'3'";}' a:3:{s:6:"course";s:16:"'Basic Numeracy'";s:5:"Grade";s:3:"'U'";s:4:"Unit";s:3:"'2'";}.......}

请任何人帮助我，因为我是php mysql的新手。

感谢。

你正在接近这个问题。您不需要序列化任何内容。我建议在php.net上阅读serialize（）做什么以及它有用的地方。要更新数据库，您只能发出1个查询。由于这似乎是一个学校项目，我不会试图为你解决 - 上述提示应该有助于研究和自己得出结论：）
