如何爆炸前10个字符串的元素忽略其余的（逗号分隔）

Question

我想将以下字符串分解为10个元素

$str = "a,b,c,d,e,f,g,h,i,j,k,l,m,n,o";

进入数组$ arr.Tried with

$arr = explode(",", $str,10);

结果为

Array
(
[0] => a
[1] => b
[2] => c
[3] => d
[4] => e
[5] => f
[6] => g
[7] => h
[8] => i
[9] => j,k,l,m,n,o
)

不希望$arr[9]=j,k,l,m,n,o成为$arr[9]=j。

Answer 1

你走了：

$str = "a,b,c,d,e,f,g,h,i,j,k,l,m,n,o";
$arr = explode(",", $str);
$output = array_slice($arr, 0, 10);   // returns a to j
