腓 - 字符串數組3名維

Question

我來給你找我的問題的解決方案：

我有一個扁帶是這樣的：

$chaine = "519637824467582931832419576721894365346125789985376412698243157273951648154768293"; 

我想這個二維陣列鏈式轉換，這種格式在這裏：

$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], 
]; 

我有$ grille_splited = str_split ($ string, 9);的初步反應，我得到一個表：

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

我錯過了我相信的維度？

您需要在9字符的字符串執行aditional的分裂：

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

/*$output equals
