For 循环创建额外的列

Question

这段代码显示了一个基本的树形结构括号，我正在尝试完成它以现在执行以下操作：-

1. 显示位置：

   style="border-right:2px solid #000;"

   我正在尝试为每一行使用此边框，但此脚本不会在团队/种子之间创建行来定义边框，我正在尝试为每个 TEAM 1 到 TEAM 的每一行显示边框右2 等以及所有其他回合 TEAM 1 到 TEAM 2 等。

2. PHP 错误报告正在返回以下行，在 } ELSE {? 之后还有一个未定义的偏移量？

   $line[$i] .= '<td align="center" style="border-right:2px solid #000;" colspan="2">vs</td>';
   

   3.

           $array = array('Team 1', 'Team 2', 'Team 3', 'Team 4', 'Team 5', 'Team 6', 'Team 7', 'Team 8');
           $j = count($array);
           for ($a=0; pow(2, $a) <= $j; $a++) //determine the highest power of 2 that will go into the array count
           {
               $y[$a] = 1;
               $maxpower = $a;
           }
           for ($i=1; $i < $j*2; $i++)
           {
               if($i % 2 != 0) //odd number rows for teams
               {
                   $line[$i] = '<td class="pf_title_bg" style="border-right:2px solid #000;">' . $array[($i-1)/2] . '</td>
                                <td class="pf_content_bg" style="border-right:2px solid #000;">&nbsp;</td>';
               }
               else
               {
   
                   for($b=0; $b<=$maxpower; $b++)
                   {
   
                       $round = $b+1;              
                       $line2[$b] = ($b < $maxpower ? "<th colspan='2'>Round {$round}</th>" : "<th colspan='2'>Winner</th>");
   
                       if($i % pow(2, $b) == 0) //even rows for future rounds. every 2^1 rows for first winner, 2^2 for second winner, 2^3 for third and so on.
                       {
                           if($i % pow(2, $b+1) != 0) //does not divide by the next power of 2, so this must be the last available cell
                           {
                               $line[$i] .= '<td class="pf_title_bg" style="border-right:2px solid #000;">Team '.$b.'_'.($y[$b]++).'</td>
                                             <td class="pf_content_bg" style="border-right:2px solid #000;">&nbsp;</td>';
                           }
                           else //the input will be added in a future round
                           {
                               $line[$i] .= '<td align="center" style="border-right:2px solid #000;" colspan="2">vs.</td>';
                           }
                       }
                   }
               }
           }

           eval ("\$content = \"".$this->gettemplate("table_header")."\";");
   
           $content.="<thead><tr>";
   
           foreach($line2 as $col) 
           {
               $content.=$col;
           }
   
           $content.="</tr></thead>";
   
           foreach($line as $row)
           {
               $content.="<tbody><tr>{$row}</tr></tbody>";
           }
   
           eval ("\$content.= \"".$this->gettemplate("table_footer")."\";");
   

非常感谢任何帮助

您没有正确构建表格；您在每一行周围都放置了一个 tbody 标签，从而使您的 HTML 无效。这对我有用：

<?php
$array = array('Team 1', 'Team 2', 'Team 3', 'Team 4', 'Team 5', 'Team 6', 'Team 7', 'Team 8');
            $j = count($array);
            for ($a=0; pow(2, $a) <= $j; $a++) //determine the highest power of 2 that will go into the array count
            {
                $y[$a] = 1;
                $maxpower = $a;
            }
            for ($i=1; $i < $j*2; $i++)
            {
                if($i % 2 != 0) //odd number rows for teams
                {
                    $line[$i] = '<td class="pf_title_bg" style="border-right:2px solid #000;">' . $array[($i-1)/2] . '</td>'.PHP_EOL.'<td class="pf_content_bg" style="border-right:2px solid #000;">&nbsp;</td>'.PHP_EOL;
                }
                else
                {

                    for($b=0; $b<=$maxpower; $b++)
                    {

                        $round = $b+1;
                        $line2[$b] = $b < $maxpower ? "<th colspan='2'>Round {$round}</th>".PHP_EOL : "<th colspan='2'>Winner</th>".PHP_EOL;

                        if($i % pow(2, $b) == 0) //even rows for future rounds. every 2^1 rows for first winner, 2^2 for second winner, 2^3 for third and so on.
                        {
                            if($i % pow(2, $b+1) != 0) //does not divide by the next power of 2, so this must be the last available cell
                            {
                                $line[$i] .= '<td class="pf_title_bg" style="border-right:2px solid #000;">Team '.$b.'_'.($y[$b]++).'</td>'.PHP_EOL.'<td class="pf_content_bg" style="border-right:2px solid #000;">&nbsp;</td>';
                            }
                            else //the input will be added in a future round
                            {
                                $line[$i] .= '<td align="center" style="border-right:2px solid #000;" colspan="2">vs.</td>'.PHP_EOL;

                }
            }

            //name="WIN'.$b.'_'.($y[$b]++).'

            //eval ("\$content = \"".$this->gettemplate("table_header")."\";");

            $content="<table><thead><tr>";

            foreach($line2 as $col)
            {
                $content.=$col;
            }

            $content.="</tr></thead><tbody>".PHP_EOL;
