php – 如何爆炸前10个字符串的元素忽略其余的(逗号分隔)

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);

它给出了结果

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
)

不要$arr [9] = j,k,l,m,n,o应该是$arr [9] = j.

解决方法:

干得好：

$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
