PHP: How to deal with a GROUP of HTML input text fields

Question

I've got a bunch of <input type='text' name='input0' /> fields.

The user can add them dynamically so we'd get something like:

<input type='text' name='input0' />
<input type='text' name='input1' />
<input type='text' name='input2' />

...etc. We don't know how many there will be in total. When the form gets submitted, I want to loop through each of these input fields and assign them to a $_POST variable. These are NOT the only input fields in the form, there are other elements such as radio buttons, checkboxes and other text fields. My problem is I need to somehow identify these particular dynamically-generated text fields, and loop through them. How can I do this, when all I get on the server side are the names of the input fields?

Use:

<input type='text' name='input[]' />

then you can:

foreach($_POST['input'] as $input){
    echo $input;
}

One more (remotely related) question: If I'm recording each value in a MySQL DB, is it best to insert the query into the foreach loop so it's recorded with each iteration? Seems like it would take forever if there are 50 input fields. Or is there a more efficient way of recording all values with one query?

@user1775598 if you're inserting them into a database, you can build a multi-valued insert statement, like this: stackoverflow.com/questions/1307618/… then just execute it once you've finished your loop. Make sure you don't leave yourself open to mysql injections though!
