您正在寻找数学中称为矩阵转置的东西。要获得矩阵/表的转置，请将行转换为列。

<?php

$table = [
    ['Username', 'Col1', 'Col2', 'Col3', 'Col4'],
    ['Balakumar', 3, 2, 5, 85]
];

function printTable($rows) {
    foreach ($rows as $row) {
        foreach ($row as $value) {
            printf("%10s", $value);
        }
        echo PHP_EOL;
    }
}


function transposeTable($table) {
    $rowsCount = count($table);
    $columnsCount = count($table[0]);

    for ($row = 0; $row < $rowsCount; $row++) {
        for($column = 0; $column < $columnsCount; $column++) {
            $transpose[$column][$row] = $table[$row][$column];
        }
    }
    return $transpose;

}

echo 'Table :' . PHP_EOL;
printTable($table);
echo 'Transpose:' . PHP_EOL;
printTable(transposeTable($table));

?>

输出：

  Username      Col1      Col2      Col3      Col4  

  Balakumar       3         2         5        85   

  Username        Balakumar

  Col1         3      

  Col2         2

  Col3         5

  Col4        85
