如何创建具有正确格式的唯一代码

Question

我想针对特定的选定项目创建唯一代码，我的唯一代码格式是

FN1A,FN1B---------FN1Z z 循环重新开始后

FN2A,FN2B-----------FN2Z 依此类推

在这里我使用这个代码

<?php

    for($row=1; $row<=22; $row++){
        echo "<tr>";
        for ($column='A'; $column!='AA'; $column++){ 
            echo "<td> $row $column </td>";
        }   
        echo "</tr>";
    }
?>

请帮助我创建与我在此提到的格式相同的独特示例代码

Answer 1

尝试 PHP 范围

<?php

        for($row=1; $row<=22; $row++){
            echo "<tr>";
            foreach (range('A', 'Z') as $char) { // Get A - Z as array 
              echo "FN{$row}{$char}";  //Concatenate as per your requirements 
             }
            echo "</tr>";
        }
    ?>

Answer 2

  for($row=1; $row<=22; $row++){
    echo "<tr>";
    for ($column='A'; $column<='Z'; $column++){ 
        echo "<td> FN".$row . $column." </td>";
    }   
    echo "</tr>";
  }

我认为您缺少的是php中的range函数，请访问http://php.net/manual/en/function.range.php以获取详细信息，我将留下我构建的示例，问候。

<?php 

$array_alb = range('A', 'Z');
$array_num = range('1', '9');

echo '<pre>';
print_r($array_alb);
echo '</pre><pre>';
print_r($array_num);
echo '</pre>';

$prefix = 'FN';
$result  = array();

foreach ($array_num as $num) 
{
    foreach($array_alb as $letter)
    {
        $result[] = $prefix.$num.$letter;
    }
}

echo '<pre>';
print_r($result);
echo '<pre>';
?>

我知道你用我的逻辑连接的连接人，但我有一个带有特定样本的表格，我从下拉列表中选择样本一个唯一的代码生成并插入到数据库中
