如何将数组值从字符串转换为int？
问题描述：
$string = "1,2,3"
$ids = explode(',', $string);
var_dump($ids);
返回
array(3) {
[0]=>
string(1) "1"
[1]=>
string(1) "2"
[2]=>
string(1) "3"
}
我需要价值观是int类型而不是string类型。有没有比使用foreach循环数组并将每个字符串转换为int更好的方法呢？
I need for the values to be of type int instead of type string. Is there a better way of doing this than looping through the array with a foreach and converting each string to int?
答
$integerIDs = array_map('intval', explode(',', $string));
