如何调整以下代码？
我需要以下列方式创建一个表（6x6）：
代码的制作方式是，每行从10个随机数中选择6个数字，这6个数字放在表格中。
但我刚从老师那里听说需要首先创建一个表（6x6），然后必须逐个单元地生成一个数字，如果该数字已经存在则必须被忽略（不能有）重复的数字）。
如何调整以下代码（我只是不知道了）：
<!DOCTYPE html>
<html>
<head>
<title>Bingo</title>
</head>
<body>
<?php
$omvang = 5; // grootte v/d bingo kaart (2..9)
$trekkingen = 30; // aantal getrokken getallen
// initialiseer kaart
$kaart = array();
for ($i = 1; $i <= $omvang; $i++) {
// definieer range v/d regel
$regel = range($i * 10, $i * 10 + 9);
// random volgorde
shuffle($regel);
// voeg de eerste {$omvang} cijfers toe aan de kaart
$kaart[$i - 1] = array_slice($regel, 0, $omvang);
}
// bepaal trekking reeks
$trekking = range(10, $omvang * 10 + 9);
// randomize volgorde
shuffle($trekking);
// pak de eerste {$trekkingen}
$trekking = array_slice($trekking, 0, $trekkingen - 1);
// teken kaart en bewaar score
$score = array();
echo "<table style='border:1px solid blue;'>";
for ($y = 0; $y < $omvang; $y++) {
echo "<tr>";
for ($x = 0; $x < $omvang; $x++) {
$score[$y][$x] = 0;
echo "<td>";
echo $kaart[$y][$x] . "</td>";
}
echo "</tr>";
}
echo "</table>";
?>

这第一段代码是Bingo游戏的一大段代码的一部分;这是我遇到的第一个问题。

答案 0 :(得分：0)
您应首先初始化数组，然后以html格式打印。 类似的东西：
$rows = array();
for($r = 1; $r <= 6; $r++) {
$rows[$r] = array();
for($c = 0; $c < 6; $c++) {
do {
$t = rand($r * 10, ($r * 10) + 9);
} while(in_array($t, $rows[$r]));
$rows[$r][$c] = $t;
}
}
技巧部分是＆＃34; in_array＆＃34;部分：）
然后你就打印出来了：
echo '<table>';
foreach($rows as $row){
echo '<tr>';
foreach($row as $cell) {
echo '<td>' . $cell . '</td>';
}
echo '</tr>';
}
echo '</table>';
一个完整的例子，带有绘图数组：

<?php
$rows = array();
for($r = 1; $r <= 6; $r++) {
$rows[$r] = array();
for($c = 0; $c < 6; $c++) {
do {
$t = rand($r * 10, ($r * 10) + 9);
} while(in_array($t, $rows[$r]));
$rows[$r][$c] = $t;
}
}
$draw = array();
$full = false;
do {
do {
$r = rand(1, 70);
} while(in_array($r, $draw));
$draw[] = $r;
$cRows = array(0,0,0,0,0,0);
$cCols = array(0,0,0,0,0,0);
foreach($rows as $row => $cols) {
foreach($cols as $col => $number) {
if(in_array($number, $draw)) {
$cRows[$row]++;
$cCols[$col]++;
if($cRows[$row] == 6 || $cCols[$col] == 6) $full = true;
}
}
}
} while(!$full);
echo 'Numbers are: ' . implode(', ', $draw);
echo '<br /><br /><table>';
foreach($rows as $row){
echo '<tr>';
foreach($row as $cell) {
echo '<td';
if(in_array($cell, $draw)) echo ' style="color: white; background-color: blue;"';
echo '>' . $cell . '</td>';
}
echo '</tr>';
}
echo '</table>';
