Foreach 像这样遍历多维数组

Question

我在变量 $comments 中有一个多维数组，包含：

Array (
    [0] => Array
        (
            [0] => 889
            [1] => First comment
            [2] => 8128912812
            [3] => appr
        )

    [1] => Array
        (
            [0] => 201
            [1] => This is the second comment
            [2] => 333333
            [3] => appr
        )

    // There is more...
)

如何遍历此数组并使用 for each 回显每个值？

Answer 1

foreach($arrayOfArrays as $array){
    foreach($array as $index => $value){
        echo $array[$index];
    }
}

Answer 2

您应该使用两个 foreach 循环，因为您的数组必须达到以下水平：

foreach ($comments as $comment)
   foreach ($comment as $comment_data)
       echo $comment_data;

Answer 3

如果您的数组结构与您显示的一样，您可以按照以下方式执行此操作：

foreach($comments as $comment) {
    echo $comment[0];
    echo $comment[1];
    echo $comment[2];
    echo $comment[3];
}

Answer 4

只需使用两个 foreach 循环。一个在另一个里面

foreach($comments as $commentArray){
    foreach($commentArray as $comment){
        echo $comment; 
    }
}

希望对您有所帮助

Answer 5

$i=0;
$c=count($array);
while ($i<$c) {
   foreach ($array[$i] as $comment_property) {
echo $comment_property;
}
$i++;
}
