Question

它是关于for循环问题

for ($row = 1; $row <= $highestRow; $row++) {
    echo "<tr>";
    for ($column = 0; $column < $highestColumn; $column++) {
        $val = $sheet->getCellByColumnAndRow($column, $row)->getValue();
        echo "<td>";
        //echo $val;
        echo $row,$column;
        echo "</td>";
  }
  echo "</tr>";
}

在这种情况下，最高行和最高列都是4 输出：

Unname coloum 0  Unname coloum 1  Unname coloum 2  Unname coloum 3  
    13                   13               13                13
    23                   23               23                23
    33                   33               33                33
    43                   43               43                43

列的值是3并且永远不会改变（它应该至少为0？），我之前没有初始化它，这很奇怪

评论太大了：

尝试更改

$highestRow = $sheet->getHighestRow(); 
$highestColumn = PHPExcel_Cell::columnIndexFromString($sheet->getHighestColumn());

到

$highestRow = $sheet->getHighestRow(); 
$highestColumn = $sheet->getHighestColumn(); 
$highestColumn++;

和

for ($head = 0; $head < $highestColumn; $head++){  
    echo "<th field='col' $head> Unname coloum $head </th>";  
}

到

for ($head = 'A'; $head !== $highestColumn; $head++){  
    echo "<th field='col' $head> Unname coloum $head </th>";  
}

和

for ($column = 0; $column < $highestColumn; $column++) {        
    $val = $sheet->getCellByColumnAndRow($column, $row)->getValue();        
    echo "<td>";        
    //echo $val;        
    echo "$row,$column";        
    echo "</td>";        
}

到

for ($column = 'A'; $column !== $highestColumn; $column++) {     
    // $val = $sheet->getCellByColumnAndRow($column, $row)->getValue();     
    echo "<td>";     
    //echo $val;     
    echo $row , $column;     
    echo "</td>";     
}

请注意，我暂时注释掉了getCell调用

为什么在这种情况下变量列是3？
