将Array字符串转换为int

Question

How should I make this array value that is in string form

Array
(
    [0] => ["1","2"]
    [1] => ["5"]
)

into int form

Array
(
    [0] => 1
    [1] => 2
    [2] => 5
)

Is it complicated? Anyone can help?

Answer 1

You only need to loop through the two layers of your array.

$input=[["1","2"],["5"]];

foreach($input as $a){
    foreach($a as $v){
        $result[]=+$v;  // make integer
    }
}
var_export($result);
