Php-字符串到数组3维

我来找你是为了解决我的问题：

我有一根像这样的扁线：

$chaine = "519637824467582931832419576721894365346125789985376412698243157273951648154768293";

我想转换这个维度数组链，这里的格式是：

$tab = [
    [0, 0, 0, 0, 0, 0, 0, 0, 0],
    [0, 0, 0, 0, 0, 0, 0, 0, 0],
    [0, 0, 0, 0, 0, 0, 0, 0, 0],
    [0, 0, 0, 0, 0, 0, 0, 0, 0],
    [0, 0, 0, 0, 0, 0, 0, 0, 0],
    [0, 0, 0, 0, 0, 0, 0, 0, 0],
    [0, 0, 0, 0, 0, 0, 0, 0, 0],
    [0, 0, 0, 0, 0, 0, 0, 0, 0],
    [0, 0, 0, 0, 0, 0, 0, 0, 0],
];

我最初的回答是$grilly\u splited=str\u split$string，9；我得到一张桌子：

$tab = [
[000000000],
[000000000],
[000000000],
[000000000],
[000000000],
[000000000],
[000000000],
[000000000],
[000000000],
];

我错过了一个我相信的维度

编辑：对不起，伙计和Thx给了你提示！：

您需要对9个字符字符串执行传统拆分：

$string = "519637824467582931832419576721894365346125789985376412698243157273951648154768293";
$output = array_map(function($element){
    return str_split($element);
}, str_split($string, 9));

/*$output equals
