How to pass input field values ​​to an array?

Question

PHP

Good afternoon.
Help adding input field values ​​to php array.
The form:

<form method="post">
   <inpute type="text" name="optio">
   <inpute type="text" name="optio">
   <inpute type="text" name="optio">
 </form>

Well, click on the button:

if (isset($_POST['save'])) {
  $MassCh[$i]=$_POST['optio'];
}
Но при таком варианте добавляется в массив все и в одну ячейку и это не странно.

Then I tried it with an array and a script when generating a new field, a number is added to name="optio" and I add it to the cells through the array like this:

for ($i=1; $i<=$valueLine; $i++) {
            $MassCh[$i]=$_POST['option'.$i];
        }

But not sure if this is the correct solution?

Answer 1

<input type="text" name="field[]">
B $_POST['field']will already have an array of filled values.
