Php - chaîne à tableau 3 dimensions

Question

Je viens de trouver une solution à mon problème:

J'ai une chaîne plat comme ceci:

$chaine = "519637824467582931832419576721894365346125789985376412698243157273951648154768293"; 

Je veux convertir cette chaîne de tableau à deux dimensions, ce format ici:

$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], 
]; 

J'ai eu une réponse initiale avec $ grille_splited = str_split ($ string, 9); je reçois une table:

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

Il me manque une dimension que je crois?

Vous devez effectuer une scission aditional sur les 9 chaînes char:

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

/*$output equals
