我需要使用空格等删除器将数组分解为较小的数组，而不是使用一定数量的字符（因此array_chunk不适用于此和这些答案如何将数组分解为指定数量的较小数组？ 出于同样的原因无关）。
例：
$array1 = ("One two three","four five six","seven eight nine");
想将"一二三"分成一个数组中的三个元素（使用空格作为deliminator），接下来的两个元素也是如此。这可以分为多维数组也是如此。
php> $array1 = array("One two three","four five six","seven eight nine");
php> =array_map(function($a){return explode(' ',$a);},$array1)
array(
0 => array(
0 => "One",
1 => "two",
2 => "three",
),
1 => array(
0 => "four",
1 => "five",
2 => "six",
),
2 => array(
0 => "seven",
1 => "eight",
2 => "nine",
),
)
匿名函数可以更改为您认为合适的任何功能。正则表达式，随便。
编辑 根据您的评论：
php> $array1 = array("One two three","four five,six","seven,eight nine");
php> =array_map(function($a){return preg_split('/[ ,]/',$a);},$array1)
array(
0 => array(
0 => "One",
1 => "two",
2 => "three",
),
1 => array(
0 => "four",
1 => "five",
2 => "six",
),
2 => array(
0 => "seven",
1 => "eight",
2 => "nine",
),
)
