Php 在格式化的html表中打印mysqli结果

php html mysql

Php 在格式化的html表中打印mysqli结果,php,html,mysql,mysqli,html-table,Php,Html,Mysql,Mysqli,Html Table,我有一个mysqli查询，返回以下结果： +--------+------+-----------+---------+-------+----------+ | Agent | Date | operation | article | num | quantity | +--------+------+-----------+---------+-------+----------+ | Albert | D1 | SL1 | A | 0001 |

我有一个mysqli查询，返回以下结果：

+--------+------+-----------+---------+-------+----------+
| Agent  | Date | operation | article |  num  | quantity |
+--------+------+-----------+---------+-------+----------+
| Albert | D1   | SL1       | A       |  0001 |      300 |
| Albert | D1   | SL1       | A       |  0002 |      400 |

| Robert | D2   | SL3       | B       |  9999 |       90 |
+--------+------+-----------+---------+-------+----------+
查询顺序为代理ASC、日期ASC、操作ASC、艺术ASC

我试图以以下方式将结果打印到格式化的HTML表中

Agent: ALBERT
     DATE : D1
       Operation: SL1
          ARTICLE : A
             num: 0001 | Quantity: 300
             num: 0002 | Quantity: 400
     DATE : D3
       Operation: SL2
          ARTICLE : B
             num: 00046 | Quantity:100
Agent: Robert
     DATE: D3
       Operation: SL4
          ARTICLE : A
             num: 1231  | Quantity: 400
       Operation: SL5
          ARTICLE : C
             num: 888  | Quantity: 20
     DATE: DX
       Operation: SL3
          ARTICLE : B
             num: 9999  | Quantity: 90

Agent: ALBERT
     DATE : D1
       Operation: SL1
          ARTICLE : A
             num: 0001 | Quantity: 300
             num: 0002 | Quantity: 400
     DATE : D3
       Operation: SL2
          ARTICLE : B
             num: 00046 | Quantity:100
Agent: Robert
     DATE: D3
       Operation: SL4
          ARTICLE : A
             num: 1231  | Quantity: 400
       Operation: SL5
          ARTICLE : C
             num: 888  | Quantity: 20
     DATE: DX
       Operation: SL3
          ARTICLE : B
             num: 9999  | Quantity: 90
我尝试过这样做，但没有成功：

$prevAgent="";
$prevDate="";
$prevOperation="";
$prevArticle="";
$prevNum="";
while ($row = mysqli_fetch_array($result)) {
     if ($row['Agent']!= $prevAgent) {
                   echo "<tr><td>".$row['Agent']."</td><td></td><td></td><td></td><td></td><td></td></tr>";
                                }
     if ($row['date']!= $prevDate) {
                   echo "<tr><td></td><td>".$row['date']."</td><td></td><td></td><td></td><td></td></tr>";
                                }
     if ($row['Operation']!= $prevOperation) {
                   echo "<tr><td></td><td></td><td>".$row['Operation']."</td><td></td><td></td><td></td></tr>";
                                }
     if ($row['Article']!= $prevArticle) {
                   echo "<tr><td></td><td></td><td></td><td>".$row['Article']."</td><td></td><td></td></tr>";
                                }
       if ($row['Num']!= $prevNum) {
                  echo "<tr><td></td><td></td><td></td><td></td><td>".$row['numLot']."</td><td>".$row['quantity']."</td></tr>";
                                }

  $prevAgent = $row['Agent'];
  $prevDate      = $row['date'];
  $prevOperation    = $row['operation'];
  $prevArticle      = $row['article'];
  $prevNum      = $row['num'];
      }
    endif; ?>

$prevAgent=”“；
$prevDate=“”；
$prevOperation=“”；
$prevaricle=“”；

while（$row=mysqli\u fetch\u数组（$result））{

我已经为此绞尽脑汁好一阵子了。如何以以前的格式打印结果？

您需要执行两个层次移动：

$obj = [[
    "Agent" => "Albert",
    "Date" => "D1",
    "operation" => "SL1",
    "article" => "A",
    "num" => "0001",
    "quantity" => "300"
], [
    "Agent" => "Albert",
    "Date" => "D1",
    "operation" => "SL1",
    "article" => "A",
    "num" => "0002",
    "quantity" => "400"
], [
    "Agent" => "Albert",
    "Date" => "D3",
    "operation" => "SL2",
    "article" => "B",
    "num" => "00046",
    "quantity" => "100"
], [
    "Agent" => "Robert",
    "Date" => "D3",
    "operation" => "SL4",
    "article" => "A",
    "num" => "1231",
    "quantity" => "400"
], [
    "Agent" => "Robert",
    "Date" => "D3",
    "operation" => "SL5",
    "article" => "C",
    "num" => "888",
    "quantity" => "20"
], [
    "Agent" => "Robert",
    "Date" => "D2",
    "operation" => "SL3",
    "article" => "B",
    "num" => "9999",
    "quantity" => "90"
]];
$agent = [];
foreach ($obj as $val) {
    $agent[$val["Agent"]][] = $val;
}
$agentDate = [];
foreach ($agent as $agent => $val) {
    foreach ($val as $agDate => $value) {
        $agentDate[$agent][$value["Date"]] = $value;
    }
}
完成此操作后，您将以以下形式获得：

Array
(
  [Albert] => Array
    (
      [D1] => Array
        (
          [Agent] => Albert
          [Date] => D1
          [operation] => SL1
          [article] => A
          [num] => 0002
          [quantity] => 400
        )

      [D3] => Array
        (
          [Agent] => Albert
          [Date] => D3
          [operation] => SL2
          [article] => B
          [num] => 00046
          [quantity] => 100
        )

    )

  [Robert] => Array
    (
      [D3] => Array
        (
          [Agent] => Robert
          [Date] => D3
          [operation] => SL5
          [article] => C
          [num] => 888
          [quantity] => 20
        )

      [D2] => Array
        (
          [Agent] => Robert
          [Date] => D2
          [operation] => SL3
          [article] => B
          [num] => 9999
          [quantity] => 90
        )

    )

)
最后，如果你这样做：

foreach ($agentDate as $agent => $details) {
    echo "Agent: $agent\n";
    foreach ($details as $date => $value) {
        echo "\tDate: $date\n";
        echo "\t\tOperation: {$value["operation"]}\n";
        echo "\t\t\tARTICLE : {$value["article"]}\n";
        echo "\t\t\t\tnum : {$value["num"]}\n";
    }
}
您将获得以下输出：

$data=array（）；
$data[]=数组(
“代理”=>“阿尔伯特”，
“日期”=>“D1”，
“操作”=>“SL1”，
“文章”=>“A”，
'num'=>'0001'，
“数量”=>“300”，
);
$data[]=数组(
“代理”=>“阿尔伯特”，
“日期”=>“D1”，
“操作”=>“SL1”，
“文章”=>“A”，
'num'=>'0002'，
“数量”=>“400”，
);
$data[]=数组(
“代理”=>“阿尔伯特”，
“日期”=>“D3”，
“操作”=>“SL2”，
“条款”=>“B”，
'num'=>'00046'，
“数量”=>“100”，
);
$data[]=数组(
“代理”=>“罗伯特”，
“日期”=>“D3”，
“操作”=>“SL4”，
“文章”=>“A”，
'num'=>'1231'，
“数量”=>“400”，
);
$data[]=数组(
“代理”=>“罗伯特”，
“日期”=>“D3”，
“操作”=>“SL5”，
'条款'=>'C'，
'num'=>'888'，
“数量”=>“20”，
);
$data[]=数组(
“代理”=>“罗伯特”，
“日期”=>“D2”，
“操作”=>“SL3”，
“条款”=>“B”，
'num'=>'9999'，
“数量”=>“90”，
);
//代理人
$filteredAgent=array（）；
foreach（数据为$value）{
$filteredAgent[$value['Agent'][$value['Date'][$value['operation']][$value['article']]][]=$value；
}
回声“；
打印（$filteredAgent）；
foreach（$filteredAgent作为$agent=>$agentData）{
echo“Agent:$Agent”；
foreach（$agentData作为$date=>$dateData）{
回声“
”；
echo“\t日期：$date”；
foreach（$dateData作为$operation=>$operationData）{
回声“
”；
echo“\t\t操作：$operation”；
foreach（$operationData作为$article=>$articleData）{
回声“
”；
echo“\t\t\tarticle:$article”；
foreach（$articleData作为$finalData）{
回声“
”；
echo“\t\t\t\tnum:.$finalData['num']”数量：.$finalData['Quantity']；
}
}
}
}
回声“
”；
}
您尝试的方式很好，只是需要正确引用字段名：它们区分大小写

$row['Date']
和
$row['Date']
是两个不同的东西，
$row['Num']
和
$row['numLot']
。。。等等

确保
if
条件、
echo
语句和
$prevXXXX
分配中的键相同。一旦您使用了查询生成的精确密钥，它就会工作。

您尝试了什么？请添加用于获取数据和输出数据的代码。此处应该会出现语法错误，如未定义索引中的语法错误。还请将数据库查询添加到问题中，并将调试结果添加为$result和/或$row。。。您当前只显示所需内容以及如何生成输出（html），而不显示如何获取数据。。。谢谢，我不知道我怎么才能迈出第一步，把它变成object@bpax51使用您要执行的
while
循环。如果您不懂PHP，我们将无法提供帮助。至少获取SQL DML和DDL查询，以便我们提供帮助。@bpax51您所拥有的是一种类似于表的东西，而您所要求的是一种文本输出。你想要表格输出还是文本输出？哇。。。太好了<代码>:D这比我的好。但问题是，OP不懂PHP。实际上它不是复制&过去的。我可以在几分钟内写出这种逻辑；-）谢谢你的补充非常感谢Ankit vadariya:）这很有魅力
