PHP：将逗号分隔值转换为整数数组(PHP: Turn comma

PHP：将逗号分隔值转换为整数数组(PHP: Turn comma-separated values into an array of integers)

我有一串逗号分隔值： 1,2,3,4,5,6,7,8,9,10,11,12,13

如何摆脱逗号，将每个值转换为整数，最后得到这些数字的PHP数组？

$number_array = [1, 2, 3, 4 ....., 13]; - 那样的？

I've got a string of comma separated values: 1,2,3,4,5,6,7,8,9,10,11,12,13

How can I get rid of the comma, turn each value into an integer and end up with a PHP array of these numbers?

$number_array = [1, 2, 3, 4 ....., 13]; - something like that?

利用explode()

<?php $str='1,2,3,4,5,6,7,8,9,10,11,12,13'; $arr = explode(',',$str); $intarr = array_map('intval',$arr); var_dump($intarr);

好吧，一个班轮。

var_dump(array_map('intval',explode(',','1,2,3,4,5,6,7,8,9,10,11,12,13')));

OUTPUT :

array(13) { [0]=> int(1) [1]=> int(2) . . // Lines Skipped . int(12) [12]=> int(13) }

Make use of explode()

<?php $str='1,2,3,4,5,6,7,8,9,10,11,12,13'; $arr = explode(',',$str); $intarr = array_map('intval',$arr); var_dump($intarr);

Well, a one-liner.

var_dump(array_map('intval',explode(',','1,2,3,4,5,6,7,8,9,10,11,12,13')));

OUTPUT :

array(13) { [0]=> int(1) [1]=> int(2) . . // Lines Skipped . int(12) [12]=> int(13) }
