尝试使用php发布多维数组

$multiDimensionalArray = [
    ['Apple', 'Banana', 'Cherry'],
    ['Red', 'Yellow', 'Black'],
    ['Sweet', 'Tasty', 'Sour']
];

foreach ($multiDimensionalArray as $array) {
    foreach ($array as $value) {
        echo $value . ' ';
    }
    echo '<br>';
}

Apple Banana Cherry 
Red Yellow Black 
Sweet Tasty Sour 

$json = json_encode($multiDimensionalArray);
echo $json;

[["Apple","Banana","Cherry"],["Red","Yellow","Black"],["Sweet","Tasty","Sour"]]
