How to put textbox value into array only if it has value?

Question

I have created many textboxes and I want to put all of the values into array only if they have themselves filled. I need them to work as how checkbox works in HTML (only the checked ones will then put into array). I use PHP language here. How to do that?

This is my simple HTML textbox:

<input name="array[]">

Would really appreciate for any help you give to me. Much thanks!

That's what I'm thinking of but I didn't know which function should I use. Now I have my problem solved, thank you for the answer. — Alvian Casablancas

Firstly, I'd recommend you change your name to something more readable:

<input name="name[]">

Next, you want to get your data, I am assuming your form is using POST. We're going to store the form data into a $names array variable.

$names = $_POST['name'];

Next, we're going to create a new array variable which will store input values that have data.

$namesWithData = [];

We're now going to loop through the $names array. This loop will add any fields with data to the $namesWithData array.

foreach($names as $name) {
   if(!empty($name) {
      array_push($namesWithData, $name);
   }
}

The $namesWithData array has the data ready to use.

This really helps me a lot. Didn't know if there is such function like array_push(). Frankly, I am still dumb in PHP. Thanks!
