如何解码用逗号和方括号编码到数组的字符串

我自己找到了一个将字符串转换为有效JSON的解决方案。希望这能帮到大家。

$t = '[[["¡hola","hello","",""]],[["interjection",
      ["¡Hola!","¡Caramba!","¡Oiga!","¡Diga!","¡Bueno!","¡Vale!","¡Aló!"],[["¡Hola!",
      ["Hello!","Hi!","Hey!","Hullo!","Hallo!","Hoy!"],,0.70910621],["¡Caramba!",
      ["Gee!","Well!","Good gracious!","Well I never!","By jingo!","By gum!"]],["¡Oiga!",
      ["Listen!","Hello!","Hullo!","Hallo!","I say!","See here!"]],["¡Diga!",
      ["Hello!","Hullo!","Talk away!"]],["¡Bueno!",["Well!","All 
      right!","Hello!","Hallo!","Hullo!"]],
      ["¡Vale!"["Okay!","OK!","O.K.!","Okey!","Hello!"]],
      ["¡Aló!",["Hello!","Hullo!","Halliard!"]]],"Hello!",9]],"en",,[["¡hola",
      [1],true,false,999,0,2,0]],[["hello",1,[["¡hola",999,true,false],
["Hola",0,true,false],["saludar",0,true,false],["saludo",0,true,false]],
[[0,5]],"hello"]],,[,"Hello!",[10],,true],
[],3]';
    $t = str_replace(',,',',"",',$t);
    $t = str_replace('[,','["",',$t);
    $t = str_replace(',]',',""]',$t);
    $arr = json_decode($t);
    print_r($arr);
