配列を表示

Question

おはよう。

5列に配列を表示していますが、指定されたキーを持つ値が最後に到着した場合、値を最後までプッシュする必要があります。

<?php 

$say = array("1","2","3","4","m"=>"5","s"=>"6","7","8","9","10","11","12"); 

$columns = 5; 

for ($p=0; $p <count($say); $p++) { 


    if ($p==0) { 
      print "<table><tr>"; 
    } elseif ($p%$columns == 0) { 
      print "<tr>"; 
    } 

    print "<td>".htmlspecialchars($say[$p])."</td>"; 


    if (($p+1)%$columns == 0) { 
      print "</tr>"; 
    } 
    if ($p==count($say)-1) { 
      $empty = $columns - (count($say)%$columns) ; 
      if ($empty != $columns) { 
        print "<td colspan=$empty>&nbsp;</td>"; 
        } 
      print "</tr></table>"; 
    } 
    } 
    ?>

で表示するには、このコードを使用し、これはあなたの問題を解決する必要があります。

<?php 

// Returns TRUE is the value is non-numeric otherwise FALSE. 
function is_non_numeric($value) 
{ 
    return ! is_numeric($value); 
} 

// The number of columns 
$columns = 5; 

// The data 
$data = array('1', '2', '3', '4', 'm' => '5', 's' => '6', '7', '8', '9', '10', '11', '12'); 

// Chunk the data into rows of {$columns} columns. 
$rows = array_chunk($data, $columns, TRUE); 

// Output the table if there are rows. 
if (! empty($rows)) 
{ 
    echo '<table>'; 

    // Loop through each rows. 
    foreach ($rows as $row) 
    { 
    // Find all non-numeric keys, if any. 
    $non_numeric_keys = array_filter(array_keys($row), 'is_non_numeric'); 

    // Loop through each non-numeric keys if one or more were found. 
    if (! empty($non_numeric_keys)) 
     foreach ($non_numeric_keys as $offset => $non_numeric_key) 
     { 
     // Skip this one of the non-numeric key isn't the first or last of the row. 
     if ($offset != 0 && $offset != ($columns - 1)) 
      continue; 

     // Remove the value with a non-numeric key from the row. 
     $value = array_splice($row, $offset, 1); 

     // Randomly select where the value will be re-inserted. 
     $random = rand(1, ($columns - 2)); 

     // Re-insert the value with a non-numeric key. 
     array_splice($row, $random, 0, $value); 
     } 

    echo '<tr>'; 

    // Loop through each columns. 
    foreach ($row as $index => $column) 
     echo '<td>' . $column . '</td>'; 

    // If the row doesn't have {$columns} columns add one that spans the number of missing columns. 
    if (($colspan = $columns - count($row)) != 0) 
     echo '<td colspan="' . $colspan . '">&nbsp;</td>'; 

    echo '</tr>'; 
    } 

    echo '</table>';
