foreach循环中显示多维数组

Question

我想在foreach循环中显示多维数组。

$result = mysql_query("SELECT * FROM `marvin`.`moje`;");
$i = 0;
while($row = mysql_fetch_array($result)){
    $sql[$i] = array($row['id'], $row['name'], $row['price'], $row['material']);
    $i++;
}

如何写循环现在多维数组$sql[$i] ?我真的想用foreach循环。请不要写while循环

谢谢。

Answer 1

就像这样简单:

foreach ($sql[$i] as $sqld) {
      echo $sqld;
    }

所以应该是这样的:

$result = mysql_query("SELECT * FROM `marvin`.`moje`;");
$i = 0;
while($row = mysql_fetch_array($result)){
    $sql[$i] = array($row['id'], $row['name'], $row['price'], $row['material']);
    foreach ($sql[$i] as $sqld) {
      echo $sqld;
    }
    $i++;
}

如果你想在while循环之外显示它:

foreach ($sql as $sqli) {
    foreach ($sqli as $sqld) {
       echo $sqld;
    }
}
